In all, there is a guarantee that this book will be a very helpful and effective tool for the job-seekers by providing them with all the inputs and guiding them towards their placement in the companies.
Recruitment Patterns of various MNC’s Various MNC‟s have different patterns for recruitment but the skeletal structure of the patterns is commonly aid to be as follows:
Round I: Written test on aptitude Round II: Written test on technical knowledge Round III: Group Discussion Round IV: Technical Interview Round V: HR Interview So unless you prove yourself in aptitude test you will never get a chance to prove any other expertise you possess in other aspects. This is the reason why aptitude is considered the most important factor by the aspirants of various MNC recruitments.
Importance of aptitude in recruitment process Aptitude test is the first round of recruitment process for any company in any sector like Banking, Software, Insurance, Pharmaceutics etc. All the graduates with 60% or above are eligible for the recruitment process and everyone is tested on the same
grounds of aptitude. This gives us the clear idea that the companies are giving aptitude more importance than the academic percentages.
What is aptitude? Aptitude literally means a natural talent. It is something that comes with us by our birth. But it is to be explored and developed within by us and that can be achieved by understanding and practicing the concepts of aptitude. The candidates with good aptitude skills are considered better than others because they are fast at their mind and good at problem solving skills. Thus aptitude has become the most important soft skill these days.
Why aptitude? Even if the candidate is good at academics and communication skills, he will not get a chance to prove them unless he passes through the initial round of aptitude testing. So we can conclude that without appropriate levels of aptitude an aspirant can never achieve success in the recruitment process of any corporate sector company. This book helps all the aspirants in clearly understanding the concepts of aptitude that are required for the recruitment processes of various companies. For further practice on these concepts covered in the book you can refer to the books on aptitude by Pearson Education like Test of reasoning and general intelligence by Showick Thorpe and Quantitative Techniques by Khattar.
QUANTITATIVE APTITUDE
Percentages Understanding Percentages: The word percent can be understood as follows: Per cent => for every 100. So, when percentage is calculated for any value, it means that that you calculate the value for every 100 of the reference value. Why Percentage? Percentage is a concept evolved so that there can be a uniform platform for comparison of various things. (Since each value is taken to a common platform of 100.) Eg: To compare three different students depending on the marks they scored we cannot directly compare their marks until we know the maximum marks for which they took the test. But by calculating percentages they can directly be compared with one another. Before going deeper into the concept of percentage, let u have a look at some basics and tips for faster calculations: Calculation of Percentage: Percentage = (Value / Total value) X 100 Eg: 50 is what % of 200? Soln: Percentage = (50/200) X 100 = 25%. Calculation of Value: Value = (Percentage/100) X total value Eg: What is 20% of 200? Soln: Value = (20/100) X 200 Note: Percentage is denoted by “%”, which means “/100”. Eg: What is the decimal notation for 35%? Soln: 35% = 35/100 = 0.35.
For faster calculations we can convert the percentages or decimal equivalents into their respective fraction notations.
Percentages – Fractions Conversions: The following is a table showing the conversions of percentages and decimals into fractions: Percentage

Similarly we can go for converting decimals more than 1 from the knowledge of the above cited conversions as follows: We know that 12.5% = 0.125 = 1/8 Then, 1.125 = [8(1)+1]/8 = 9/8 (i.e., the denominator will add to numerator once, denominator remaining the same. Also, 2.125 = [8(2)+1]/8 = 17/8 (here the denominator is added to numerator twice) 3.125 = [8(3)+1]/8 = 25/8 and so on. Thus we can derive the fractions for decimals more than 1 by using those les than 1. We will see how use of fractions will reduce the time for calculations: Eg: What is 62.5% of 320? Soln: Value = (5/8) X 320 (since 62.5% = 5/8) = 200. Percentage Change: A change can be of two types – an increase or a decrease. When a value is changed from initial value to a final value, % change = (Difference between initial and final value/initial value) X 100 Eg: If 20 changes to 40, what is the % increase? Soln: % increase = (40-20)/20 X 100 = 100%. Note: 1. If a value is doubled the percentage increase is 100. 2. If a value is tripled, the percentage change is 200 and so on. Percentage Difference: % Difference = (Difference between values/value compared with) X 100. Eg: By what percent is 40 more than 30? Soln: % difference = (40-30)/30 X 100 = 33.33% (Here 40 is compared with 30. So 30 is taken as denominator)
Eg: By what % is 60 more than 30? Soln: % difference = (60-30)/30 X 100 = 100%. (Here is 60 is compared with 30.) Hint: To calculate percentage difference the value that occurs after the word “than” in the question can directly be used as the denominator in the formula.
Important Points to Note: 1. When any value increases by a. 10%, it becomes 1.1 times of itself. (since 100+10 = 110% = 1.1) b. 20%, it becomes 1.2 times of itself. c. 36%, it becomes 1.36 times of itself. d. 4%, it becomes 1.04 times of itself. Thus we can see the effects on the values due to various percentage increases. 2. When any value decreases by a. 10%, it becomes 0.9 times of itself. (Since 100-10 = 90% = 0.9) b. 20%, it becomes 0.8 times of itself c. 36%, it becomes 0.64 times of itself d. 4%, it becomes 0.96 times of itself. Thus we can see the effects on a value due to various percentage decreases. Note: 1. When a value is multiplied by a decimal more than 1 it will be increased and when multiplied by less than 1 it will be decreased. 2. The percentage increase or decrease depends on the decimal multiplied. Eg: 0.7 => 30% decrease, 0.67 => 33% decrease, 0. 956 => 4.4% decrease and so on. Eg: When the actual value is x, find the value when it is 30% decreased.
Soln: 30% decrease => 0.7 x. Eg: A value after an increase of 20% became 600. What is the value? Soln: 1.2x = 600 (since 20% increase) x = 500. Eg: If 600 is decrease by 20%, what is the new value? Soln: new value = 0.8 X 600 = 480. (Since 20% decrease) Thus depending on the decimal we can decide the % change and vice versa. Eg: When a value is increased by 20%, by what percent should it be reduced to get the actual value? Soln: (It is equivalent to 1.2 reduced to 1 and we can use % decrease formula) % decrease = (1.2 – 1)/1.2 X 100 = 16.66%. 3. When a value is subjected multiple changes, the overall effect of all the changes can be obtained by multiplying all the individual factors of the changes. Eg: The population of a town increased by 10%, 20% and then decreased by 30%. The new population is what % of the original? Soln: The overall effect = 1.1 X 1.2 X 0.7 (Since 10%, 20% increase and 30% decrease) = 0.924 = 92.4%. Eg: Two successive discounts of 10% and 20% are equal to a single discount of ___ Soln: Discount is same as decrease of price. So, decrease = 0.9 X 0.8 = 0.72 => 28% decrease (Since only 72% is remaining).

b. 90%
c. 85%
Solutions: 1. 1/5 X 2/5 X a = ¼ X a X b => b = 8/25 2. % difference = (200-50)/50 X 100 = 300 % 3. % increase = (80-30)/30 X 100 = 166.66 % 4. 1.3 x = 78000 => x = 60000. 5. Net effect = 1.2 X 1.1 X 0.7 = 0.924 => 7.6% decrease. 6. Let I be the income. Expenditure = 0.8I
Savings = 0.2I => 20%
New income = 1.2I (since 20% rise) New expenditure = (0.8I) X 1.3 (Since 30% rise) = 1.04I So, new savings = 1.2I – 1.04I = 0.16I => 16%
D. 95%
(So income decreased form 20% to 16%) % decrease = (20-16)/20 X 100 = 20%. 7. It is equivalent to 1.25 decreased to 1. % decrease = (1.25-1)/1.25 X 100 = 20% 8. % change in area = 1.2 X 1.2 (since area = side X side) = 1.44 => 44%. 9. It is equivalent to 1.25 decreased to 1. So 20% decrease. 10.
Valid Votes:
A got 56% => B got 44% Difference = 12% = 48000 So, 100% = 400000. These are valid votes. But valid votes are only 80% of total votes. So, 80% of total votes = 400000 => total votes = 500000 11.
Total money = Rs. 300.
Saving of the lady = 10% of 300 = 30/With 30/- she bought 5 kg sugar => each kg costs Rs. 6/12.
In 20lt, salt = 20% => 4 lt.
New volume = 18 lt (2 lt evaporated) So, new % = 4/18 X 100 = 22.22% 13.
% correction = (58-46.4)/58 X 100 = 20%
14. Three successive decreases of 20%, 20% and 10% => 0.8 X 0.8 X 0.9 = 0.576 Again 10% decrease => 0.576 – 0.1 = 0.476. So, 0.476 x = 9520 => x = 20000. 15.
Total discount = 0.9 X 0.8 X 0.7 = 0.504 of actual price.
So, price = 0.504 X 10000 = 5040.
16.
In 10 lt, alcohol is 10% = 1 lt.
Let x lt alcohol is added. So, (1+x)/(10+x) = 20% = 1/5 => x = 1.25 lt. 17.
A = 2B and B = 3C (ince 200% more)
A = 6C => 500 % more. 18.
50% of max marks – 40% of max marks = 25
max marks = 250 Pass marks = 40% of max + 10 => 100 + 10 = 110. 19.
A = 1.2 B => B = A/1.2 => 0.8333A => 16.66%.
(OR) Decrease from 1.2 to 1 => 16.66%. 20.
1.1 X 1.1 X x = 12100 => x = 10000.
21.
Salt = 15% of x = 0.15x (x = volume of solution)
Now, 0.15x/(x-30) = 20% = 1/5 (since 30 lt evaporated) x = 120 lt 22.
20% empty => 80 % full = 240 lt => 20% = 60 lt
23.
A => 1.4 X 1.4 = 1.96
B => 1.9
=> 6% difference.
24. From 1960 to 1975, in 15 years population doubled every 5 yrs => three times So, 2 X 2 X 2 = 8 times => 700% more. 25. [(75% X 60) + (x% X 20)] / 80 = 80% => x = 95. (since required is 80%) (OR) 60 out of 80 is 3/4. So, (3/4 X 75) + (1/4 X x) = 80 => x =95.
Profit and Loss What is Profit? When a person does a business transaction and gets more than what he had invested, then he is said to have profit. The profit he gets will be equal to the additional money he gets other than his investment. So profit can be understood as the extra money one gets other than what he had invested. Eg: A person bought an article for Rs. 100 and sold it for Rs. 120. Then he got Rs. 20 extra and so his profit is Rs. 20. What is Loss? When a person gets an amount less than what he had invested, then he is said to have a loss. The loss will be equal to the deficit he got than the investment. Eg: A person bought an article at Rs. 100 and sold it for Rs. 90. Then he got a deficit of Rs. 10 and so his loss is Rs. 10. Cost Price (CP): The money that the trader puts in his business is called Cost Price. The price at which the articles are bought is called Cost Price. In other words, Cost Price is nothing but the investment in the business. Selling Price (SP): The price at which the articles are sold is called the Selling Price. The money that the trader gets from the business is called Selling Price. In other words, Selling Price is nothing but the returns from a business. Marked/Market/List Price (MP): The price that a trader marks or lists his articles to is called the Marked Price. This is the only price known to the customer. Discount: The waiver of cost from the Marked Price that the trader allows a customer is called Discount.
Note: 1. Profit or loss percentage is to be applied always to the Cost Price only. 2. Discount percentage is to be applied always to the Marked Price only. Relationship Among CP, SP and MP: A trader adds his profit to the investment and sells it at that increased price. Also he allows a discount on Marked Price and sells at the discounted price. So, we can say that, o SP = CP + Profit. (CP applied with profit is SP) o SP = MP – Discount. (MP applied with discount is SP) Understanding Profit and Loss: So, by now we came to know that if CP is increased and sold it would result in profit and vice versa. Also whatever increase is applied to CP, that increase itself is the profit. For Rs. 10 profit, CP is to be increased by RS. 10 and the increased price becomes SP. For 10% profit, CP is to be increased by 10% and it is the SP. (From previous chapter we know that any value increased by 10% becomes 1.1 times.) So, for 10% profit, CP increased by 10% => 1.1CP = SP. o SP = 1.1CP => SP/CP = 1.1 => 10% profit o SP = 1.07CP => SP/CP = 1.07 => 7% profit o SP = 1.545CP => SP/CP = 1.545 => 54.5% profit and so on. Similarly, o SP = 0.9CP => SP/CP = 0.9 => 10% loss (Since 10% decrease) o SP = 0.76CP => SP/CP = 0.76 => 24% loss and so on. So, to calculate profit % or loss %, it is enough for us to find the ratio of SP to CP. Note: 1. If SP/CP > 1, it indicates profit. 2. If SP/CP < 1, it indicates loss. Multiple Profits or losses: A trader may sometimes have multiple profits or losses simultaneously. This is equivalent to having multiple changes and so all individual changes are to be multiplied to get the overall effect. Examples: 1. A trader uses a 800gm weight instead of 1 kg. Find his profit %. Soln: (He is buying 800 gm but selling 1000 gm. So, CP is for 800 gm and SP is for 1000 gm.) SP/CP = 1000/800 = 1.25 => 25% profit.
2. A trader uses 1 kg weight for 800 gm and increases the price by 20%. Find his profit/loss %. Soln: 1 kg weight for 800 gm => loss (decrease) => 800/1000 = 0.8 20% increase in price => profit (increase) => 1.2 So, net effect = (0.8) X (1.2) = 0.96 => 4% loss. 3. A milk vendor mixes water to milk such that he gains 25%. Find the percentage of water in the mixture. Soln: To gain 25%, the volume has to be increased by 25%. So, for 1 lt of milk, 0.25 lt of water is added => total volume = 1.25 lt % of water = 0.25 / 1.25 X 100 = 20%. 4. A trader bought an item for Rs. 200. If he wants a profit of 22%, at what price must he sell it? Soln: CP=200, Profit = 22%. So, SP = 1.22CP = 1.22 X 200 = 244/-. 5. A person buys an item at Rs. 120 and sells to another at a profit of 25%. If the second person sells the item to another at Rs. 180, what is the profit % of the second person? Soln: SP of 1st person = CP of 2nd person = 1.25 X 120 = 150. SP of 2nd person = 180. Profit % = SP/CP = 180/150 = 1.2 => 20%. 6. A milk vendor mixes water to 20 lt of milk such that the ratio of milk and water is 4:3. He sold the mixture at Rs. 12 per liter but bought the milk at Rs. 10 per liter. Find the profit % of the vendor. Soln: milk : water = 4:3 => he bought 4 parts (milk) but sold 7 parts (mixture) CP = 10 and SP = 12.
So, profit % = (SP/CP) X (SP/CP) = (7/4) X (12/10) = 2.1 => 110% gain. 7. A trader buys some apples at a price of 10 apples for Rs. 8 and sold them at a price of 8 apples for Rs. 10. Find his profit or loss %. Soln: He bought 10 apples for Rs. 8 and sold 8 apples for Rs. 10 => clearly got profit SP > CP => (SP/CP) X (SP/CP) = (10/8) X (10/8) = 100/64 = 1.5625 => 56.25 % gain. 8. A trader allows a discount of 25% on his articles but wants to gain 50% gain. How many times the CP should be marked on the items? Soln: CP applied with profit = MP applied with discount = SP 1.5CP = 0.75MP (since 50% gain and 25% discount) => MP = 2CP. 9. By selling an item at a price a trader gains 40%. What is the profit / loss % if the item is sold at half the price? Soln: SP =1.4CP => (SP/2) = 0.7CP => 30% loss. 10.
A trader gets a profit of 25% on an article. If he buys the article at 10%
lesser price and sells it for Rs. 2 less, he still gets 25% profit. Find the actual CP of the article. Soln: 25% gain => SP = 1.25CP…..1. Now, CP is 10% less => 0.9CP and SP is Rs. 2 less => (SP-2). Still, profit is 25% => (SP-2)=1.25(0.9CP) , where SP = 1.25CP (From 1) CP = Rs. 16. 11.
A trader gets a discount of 20% from the dealer and marks it at 20%
more price then the actual MP to the customer. Find his overall gain %. Soln: Let MP be the price on the item. Then, CP=0.8MP (20% discount) and SP = 1.2MP. So, gain => SP/CP = 1.2/0.8 = 1.5 => 50%.
12.
A trader allows a discount of 20% to the customer after marking the
item up by 25%. Find his gain/loss% if he is given a commission of 20% of the MP by the dealer. Soln: Trader‟s SP = 0.8 X (1.25MP) = MP (since 20% discount on 25% raised price) Trader‟s CP = 0.8 MP (20% commission) So, gain = SP/CP = MP/0.8MP = 1.25 => 25%.

Solutions: 1. Profit at a price = loss at other price => CP must be numerically between those prices
CP = (56+42)/2 = Rs. 49.
2. Gain % = 1000/880 => 1. 1363 => 13.63% 3. For P, SP=1080 and loss=10% => CP = 1080/0.9 =1200 => loss = 1200-1080 = 120. For Q, SP=1800 and loss=10% => CP = 1800/0.9 = 2000 => loss = 2000-1800 = 200. 4. She got profit => profit % = 15/10 X 12/12 = 1.5 => 50%. 5. Profit % = 19 1/21 => 1.19047. Let he measure x cm for 100 cm. Then, 100/x = 1.19047 => x=84 cm So he measures 16 cm less for every meter. 6. Loss = 30% on CP i.e., 0.3CP => SP = 0.7CP
Loss % on SP = loss/SP X 100 = 0.3CP/0.7CP X 100 = 42.85%. 7. Total CP = 90000 & total SP = 93000 => gain = SP/CP = 93000/90000 =1.0333 = 3.33% 8. Total cost of a watch = 180 + (500/100) = 185. Gain = 20% => SP = 1.2CP = 1.2 X 185 = 222 9. 0.75 MP = 0.8 CP (since 20% loss) So, MP = 1.0666CP => 6.66% gain 10.
1.2 X 1.25 X 0.6666 X CP = 1000 => CP = 1000 (profits of
20%, 25% & loss of 33.33%) 11.
Total CP=18000+1800 = 19800. Depreciation = 9.09% and gain = 11.11% => SP = (0.9091)X(1.1111)X19800
= 20000. 12.
Let „f‟ be the factor of discount => 1000 X f X f X f = 729 => f =
0.9 => 10% decrease. 13.
CP/5 = SP/6 => SP/CP=1.2 => 20% gain.
14.
In two transactions B is gaining => SP > CP for B in two
transactions. So, gain% = 12/9 X 12/9 = 1.7777 => 77.77%. 15.
2 articles free for every 10 articles bought. So 10 free articles => 50
articles bought. Money of 60 articles (10 articles free) is obtained by selling only 10 articles. So SP of 10 articles = CP of 60 articles => SP/CP = 6 => 500% gain. 16.
Total CP = 45000. Depreciation = 20% =>new CP = 0.8 X 45000 =
36000. SP = 40000 => SP/CP = 40/36 = 1.1111 => 11.11% gain
17. CP => 6 apples for Rs. 10.
SP => 4 apples for Rs. 10 => 6 apples for Rs. 15
So, for 6 apples, gain is Rs.5 => Rs. 60 gain requires 72 apples. 18.
CP of 5 kg ghee = 300. Loss = 10% => SP = 0.9 CP = 270. For Rs. 270, 4
kg are sold 19.
SP for 1 kg = 270/4 =Rs. 67.5
Let w be the weight of the second stone. Now, 0.9 X (1000/800) X (1000/w) = 1.0285 (since profit is 2.85%)
20.
w = 900 gm (nearly)
SP = 39. Profit % = CP. CP + (CP% of CP) = SP => CP = 30/-.
21.
ratio = 3:4 => investments are 3/7 and 4/7.
Overall loss/gain % = (3/7)(-10) + (4/7)(20) = 50/7 = 7 1/7 %. 22.
3/5th are sold at gain of 25% and 2/5th are sold at loss of 25%. First, (3/5 X 25 – 2/5 X 25) = 5% gain.
23.
20% gain => SP = 1.2 CP. New CP = 0.9 CP and New SP = SP + 18 => 1.2CP+18. 40% gain => new SP = 1.4 X new CP => (1.2CP+18) = 1.4(0.9CP) => CP =
300. 24.
20% gain => SP = 1.2CP.
New CP = CP – 100 and new SP = SP -100 & 24% gain => new SP=1.4 X new CP 25.
CP – 100 = 1.4 ( 1.2CP – 100) => CP = 600.
Let each article costs x => Total CP = 2x and SP = 1.3 X 2x = 2.6x.
New total CP = 0.8x + 1.1x = 1.9x, New SP = SP – 48 = 2.6x – 48 and gain = 20% So, 2.6x – 48 = 1.2 X 1.9x => 2x = 300. 26.
MP = 1.4CP. Also 10% change is discount => Rs. 42 gain => 10% of
1.4CP = 42
27.
CP = 300.
MP = 15000. 5% change in discount i.e., 5% of MP = 7.5 % of CP (profit
change) So, CP = 5/7.5 X MP = 10000. 28.
MP = 300. SP = 1.5 X discount. Now, SP = MP – discount => SP = 180.
29.
CP of apple = 0.6666 X CP of mango…….1 Man sold 4 apples for CP of 5 mangoes => his CP = 4 X CP of apple And his SP = 5 X CP of mango. So, SP/CP = (5XCP of mango)/(4XCP of apple) = 1.875 => 87.5%.
30.
SP of 18 articles = CP of 20 articles => SP/CP = 20/18 = 1.1111 =>
11.11% gain 31.
If CP is raised by 3x %, the discount should be 2x %.
Also, after discount SP=CP => increase of 3x% X decrease of 2x%. From inspection, 33.33% discount => 50% increase (since 3:2) and 1.5 X 0.6666 = 1. 32.
CP of first two articles are in ration of 3:4. So for 2 articles, gain/loss % = (3/7)X10 – (4/7)X7.5 = 0.
So, overall profit/loss% = 0 => (3/12)X10 – (4/12)X7.5 + (5/12)x = 0 => x=0%. 33.
Overall profit = 1.05 X (1.25/1) = 1.3125 => 31.25% gain
34.
For mango, SP = 1.2 CPm and for banana SP = 1.25 CPb. Revenue from mango = revenue from banana => 1.2 CPm = 4 X 1.25
CPb (since they are sold in ratio of 1:4) So, CPb/CPm = 6:25. 35.
150 pens for Rs.1000 => total CP = 1000.
1 pen free for every 9 pens => he can sell 135 pens (for least possible profit) SP of each pen = 10 and discount = 20% => SP = 8.
Total SP = 135 X 8 = 1080 => SP/CP = 1080/1000 = 1.08 => 8%. 36.
Profit% of MP = discount% of CP => profit%/discount% cant be
determined without the values of MP and CP. 37.
CP computer = SP TV – 1000 and SP computer = 1.3 X CP TV.
SP Computer = 1.04 SP TV => 1.3 CP TV = 1.04 SP TV => SP/CP = 1.25 => 25% gain. 38.
Without the knowledge of atleast on of the prices the ratio of CP‟s cant
be determined. 39.
MP1 = CP1 + 200 and discount = 20%.Also MP2 = 1.5CP2 and discount
= Rs. 160. Also SP1/CP1 = 8% gain. With this information it can‟t be said what is the profit % on 2nd watch. 40.
300 sold at loss of 20% and 500 old at a loss of 40% => loss% =
(3/8)X20 + (5/8)X40 = 32.5 => loss factor = 0.675 Already he got a gain by SP of 1200 = CP of 2000. So overall profit % = (2000/1200) X 0.675 = 1.125 => 12.5% gain.
Averages and Ages What is average? The concept of average is equal distribution of the overall value among all the things or persons present there. So the formula for finding the average is as follows: Average, A = Total of all things, T / Number of things, N Therefore, Total, T = AN If any person joins a group with more value than the average of the group then the overall average increases. This is because the value in excess than the average will also be distributed equally among all the members. Similarly when any value less than the average joins the group the overall group decreases as the deficit is divided equally among all the people present there. Example:
Consider three people A, B and C with total of Rs. 30/-. Their average becomes Rs. 10/- for each. If another person D joins them with Rs. 50/- then he has Rs. 40/- more than actual average of Rs. 10/-. So this Rs. 40/- will get distributed among those four and each gets Rs. 10/-. Thus the average becomes Rs. 20/- each. Example: The average age of a class of 30 students is 12. If the teacher is also included the average becomes 13 years. Find the teacher‟s age. Soln: When the teacher is included there are totally 31 members in the class and the average is increased by 1 year. This means that everyone got 1 extra year after distributing the extra years of the teacher. So extra years of the teacher are as follow: 31x1=31 years. Age of the teacher = actual avg + extra years = 12 + 31 = 43 years.
Exercise: 1. The average of 13 papers is 40. The average of the first 7 papers is 42 and of the last seven papers is 35. Find the marks obtained in the 7th paper?

Ratios and Proportions What is a ratio? A ratio is a representation of distribution of a value present among the persons present and is shown as follows: If a total is divided among A, B and C such that A got 4 parts, B got 5 parts and C got 6 parts then it is represented in ratio as A:B:C = 4:5:6. So, 4:5:6 means that the total value is divided into 4+5+6 = 15 equal parts and then distributed as per the ratio. Example 1:
Divide Rs. 580 between A and B in the ratio of 14:15. Soln: A:B = 14:15 => 580 is divided into 29 equal parts => each part = Rs. 20. So A‟s share = 14 parts = 14 x 20 = Rs. 280 B‟s share = 15 parts = Rs. 300. Example 2: If A:B = 2:3 and B:C = 4:5 then find A:B:C. Soln: To combine two ratios the proportions common for them shall be in equal parts. Here the common proportion is B for the given ratios. Making B equal in both ratios they become 8:12 and 12:15 => A:B:C = 8:12:15. Example 3: Three numbers are in the ratio of 3: 4 : 8 and the sum of these numbers is 975. Find the three numbers. Soln: Let the numbers be 3x, 4x and 8x. Then their sum = 3x+4x+8x = 15x = 975 => x = 65. So the numbers are 3x = 195, 4x = 260 and 8x = 520. Example 4: Two numbers are in the ratio of 4 : 5. If the difference between these numbers is 24, then find the numbers. Soln: Let the numbers be 4x and 5x. Their difference = 5x – 4x = x = 24 (given). So the numbers are 4x = 96 and 5x = 120. Example 5: Given two numbers are in the ratio of 3 : 4. If 8 is added to each of them, their ratio is changed to 5 : 6. Find two numbers. Soln: Let the numbers be a and b. A:B = 3:4 => A / B = 3 / 4. Also, (A+8) / (B+8) = 5 / 6. Solving we get, A=12 and B = 16 Example 6:
A garrison has provisions for 120 soldiers for 240 days. After 180 days 60 more soldiers will join the group. For how many more days will the provisions last? Soln: Actually after 180 days, If 120 members are there provisions come for 60 more days (since total 240 days) But now 180 members are there. So number of days = (120/180) X 60 = 40 days. Example 7: If 24 men working for 12 hrs a day can do a work in 16 days, in how many days can 8 men working 6 hrs a day do it? Soln: 24 men – 12 hrs – 16 days 8 men – 6 hrs - ? days (n) n =16 X (12 / 6) X (24 / 8) ( since no of hrs reduced no of days has to increase and no of men reduced also increases no of days i.e., inverse proportional) => n = 96 days.

Time and Distance Speed: We have the relation between speed, time and distance as follows: Speed = distance / time. So the distance covered in unit time is called speed. This forms the basis for Time and Distance. It can be re-written as Distance = Speed X Time or Time = Distance / Speed.
Units of Speed: The units of speed are kmph (km per hour) or m / s. 1 kmph = 5 / 18 m / s 1 m / s = 18 / 5 kmph
Average Speed: When the travel comprises of various speeds then the concept of average speed is to be applied. Average Speed = Total distance covered / Total time of travel
Note: In the total time above, the time of rest is not considered. Example 1: If a car travels along four sides of a square at 100 kmph, 200 kmph, 300 kmph and 400 kmph find its average speed.
Soln: Average Speed = Total distance / Total time. Let each side of square be x km. Then the total distance = 4x km. The total time is sum of individual times taken to cover each side. To cover x km at 100 kmph, time = x / 100. For the second side time = x / 200. Using this we can write average speed = 4x / (x/100 + x/200 + x/300 + x/400) = 192 kmph.
Example 2:
A man if travels at 5/6 th of his actual speed takes 10 min more to travel a distance. Find his usual time.
Soln: Let s be the actual speed and t be the actual time of the man. Now the speed is (5/6)s and time is (t+10) min. But the distance remains the same. So distance 1 = distance 2 => s X t = (5/6)s X (t+10) => t = 50 min.
Example 3: If a person walks at 30 kmph he is 10 min late to his office. If he travels at 40 kmph then he reaches to his office 5 min early. Find the distance to his office.
Soln: Let the distance to his office be d. The difference between the two timings is given as 15 min = 1 / 4 hr. Now if d km are covered at 30 kmph then time = d/30. Similarly second time = d/40. So, d/30 – d/40 = 1 / 4 => d = 30 km.
Note: When two objects move with speeds s1 and s2 a. In opposite directions their combined speed = s1 + s2 b. In same direction their combined speed = s1 ~ s2.
Example 4: Two people start moving from the same point at the same time at 30 kmph and 40 kmph in opposite directions. Find the distance between them after 3 hrs.
Soln: Speed = 30 + 40 = 70 kmph (since in opposite directions) Time = 3 hrs So distance = speed X time = 70 X 3 = 210 km.
Example 5: A starts from X to Y at 6 am at 40 kmph and at the same time B starts from Y to X at 50 kmph. When will they meet if X and Y are 360 km apart?
Soln: Distance = 360 km Speed = 40 + 50 = 90 kmph. Time = distance / speed = 360 / 90 = 4hrs from 6 am => 10 am.
Example 6: A starts from X to Y at 6 am at a speed of 50 kmph. After two hours B starts from Y to X at 60 kmph. When will they meet if X and Y are 430 km apart?
Soln: By the time B started A traveled for 2 hrs => 2 X 50 = 100 km. So at 8 am, distance = 430 – 100 = 330 km Speed = 50 + 60 = 110 kmph. Time = distance / speed = 330 / 110 = 3 hrs from 8 am => 11 am.
Note: When a train crosses a negligible length object (man / pole / tree) the distance that it has to travel is its own length. When a train has to cross a lengthy object (train / bridge / platform) the distance it has to travel is the sum of its length and the length of the object.
Example 7: If a train traveling at 40 kmph crosses another train of length 100m traveling at 14 kmph in opposite direction in 30 s find the length of the train.
Soln: Let length of train be d. Distance to be covered = d + 100. Speed = 40 + 14 = 54 kmph = 54 X 5 / 18 = 15 m / s Time = 30 s. Distance = speed X time => d+100 = 15 X 30 => d = 350 m.
Note: If a man rows a boat along the stream flowing at speed S2 then it is termed downstream speed and is given by S down = S1 + S2 , where S1 is speed of boat in still water. If a man rows a boat opposite to the stream flowing at S2 then it is termed upstream and is given by S up = S1 – S2.

Time and Work If a person can complete a work in „n‟ days then he can do 1/n part of the work in one day.
The amount of work done be a person in 1 day is called his efficiency.
Example: A can do a work in 10 days. Then the efficiency of A is given by A = 1 / 10.
Note: Number of days required to do a work = work to be done / work per day.
Example 1: If A can do a work in 10 days, B can do it in 20 days and C in 30 days in how many days will the three together do it?
Soln: The efficiencies are A = 1/10, B = 1/20 and C = 1/30 So work done per day by the three = 1/10 + 1/20 + 1/30 = 11/60 => No of days = 60/11 = 5.45 days.
Example 2: If A and B can do a work in 10 days , B and C can do it in 20 days and C and A can do it in 40 days in what time all the three can do it? Soln: A+B = 1/10 B+C = 1/20 C+A = 1/40 Adding all the three we get 2(A+B+C) = 7/40 => A+B+C = 7/80 => No of days = 80/7 days.
Note: If all the people do not work for all the time then the principle below can be used: mA + nB + oC = 1.
(1 is the total work)
Here, m=no of days A worked n=no of days B worked o=no of days C worked A,B,C = efficiencies
Example 3: If A can do a work in 12 days, B can do it in 18 days and C in 24 days. All the three started the work. A left after two days and C left three days before the completion of the work. How many days are required to complete the work?
Soln: Let the total no of days be x. A worked only for 2 days, B worked for x days and C worked for x-3 days.
So, mA + nB + oC = 1 2(1/12) + x(1/18) + (x-3)(1/24) = 1 12 + 4x + 3(x-3) = 72 x = 69 / 7 days.
Note: The ratio of dividing wages = ratio of efficiencies = ratio of parts of work done
Example 4: A can do a work in 10 days and B can do it in 30 days and C in 60 days. If the total wages for the work is Rs. 1800 what is the share of A?
Soln: Ratio of wages = 1/10 : 1/30 : 1/60 = 6 : 2 : 1 (Multiplying each term by LCM 60) So total 9 equal parts in Rs. 1800 => each part = Rs. 200 => share of A = 6 parts = Rs. 1200.
Note: When pipes are used filling the tank they are treated similar to the men working but some outlet pipes emptying the tank are present whose work will be considered negative.
Example 5: A pipe can fill a tank in 5 hrs but because of a leak a the bottom it takes 1 hr extra. In what time can the leak alone empty the tank?
Soln: Let the filling pipe be A. A = 1 / 5. But with the leak L, A – L = 1 / 6 ( A-L because leak is outlet) So, 1/L = 1 / 5 – 1/ 6 = 1/30 => Leak can empty the tank in 30 hrs.
Example 6: A pipe A can fill the tank in 10 hrs, B can fill it in 20 hrs and C can empty in 40 hrs. All are opened at the same time. After how many hours shall the pipe B be closed such that the tank can be filled in 10 hrs?
Soln: Let the pipe B be closed after x hrs. Then A worked for 10 hrs, B worked for x hrs and C worked for 10 hrs. mA + nB – oC = 1
(since C is outlet)
10(1/10) + x(1/20) – 10(1/40) = 1
x = 5 hrs.

Interest
Read this please: Raju borrowed Rs.1000 from Ramesh. After some days Raju paid back Rs.1200 to Ramesh. Means Raju paid Rs.200 excess than the amount he borrowed from Ramesh. This excess amount is called interest. The total amount of money borrowed by Raju from Ramesh is called the Principal or Sum. The money paid back to Ramesh, which is the combination of both Principal and interest is called the Amount. So, Amount = Principal + Interest Rate of interest: The interest is usually charged according to a specified term, which is expressed as some per cent of the principal and is called the rate of interest for the fixed period of time. If the fixed period is a year, the rate of interest is charged annually. If the fixed period is six months, the rate of interest is charged semiannually. If the fixed period is three months, the rate of interest is charged quarterly. If the fixed period is a month, the rate of interest is charged monthly. Example: If the rate of interest is 10% per annum, then the interest payable on Rs.100 for one year is Rs.10. Simple Interest: When the interest is payable on the principal only, it is called the simple interest. It is the interest calculated on the principal for the entire period it is borrowed. It is denoted by S.I. Example: S.I. on Rs.100 at 10% per annum will be Rs.10 each year. At the end of one year, the total amount will be Rs.100+10 = Rs.110. At the end of second year, the total amount will be Rs.100+10+10 = Rs.120 and so on. Formulae: 1. If P stands for Principal, R the rate per cent per annum, T the number of years, A the amount and S.I. the simple interest then S.I. = P T R 2. 3. 4. 5.

Clocks In a clock the most important hands are the minutes hand and the hours hand. Whatever may be the shape of the dial they move in a circular track. The total angle of 360 degrees in a watch is divided into 1 sectors, one for each hour. So one hour sector = 360 / 12 = 30 degrees. For every one hour (60 min), The minutes hand moves through 360 deg. The hours hand moves through 30 deg. So for every minute, The minutes hand moves through 6 deg The hours hand moves through 0.5 deg. They move in same direction. So their relative displacement for every minute is 5.5 deg. This 5.5 deg movement constitutes the movements of both the hands. So for every minute both the hands give a displacement of 5.5 deg.
Note: 1. Between every two hours i.e., between 1 and 2, 2 and 3 and so on the hands of the clock coincide with each other for one time except between 11, 12 and 12, 1. In a day they coincide for 22 times. 2. Between every two hours they are perpendicular to each other two times except between 2, 3 and 3, 4 and 8, 9 and 9, 10. In a day they will be perpendicular for 44 times. 3. Between every two hours they will be opposite to each other one time except between 5, 6 and 6, 7. In a day they will be opposite for 22 times.
Examples:
1. At what time between 5 and 6 will the hands of the clock coincide? Soln: At 5 the angle between the hands is 150 deg. To coincide, they collectively have to travel this distance. Every minute they travel 5.5 deg. So no. of minutes required to coincide = 150 / 5.5 = 300 / 11 = 27 3/11 min. 2. At what time between 6 and 7 will the hands be perpendicular?
Soln: At 6 the angle between the hands is 180 deg. To form 90 deg they have to cover 90 deg (out of 180 if 90 is covered 90 will remain) So no. of minutes required = 90 / 5.5 = 180 / 11 = 16 4/11 min. But they will be perpendicular for two times. The second one will happen after the minutes hand crosses the hours hand and then for 90 deg. So it has to travel 180+90 = 270 deg. So time = 270 / 5.5 = 540 / 11 = 49 1/11 min. 3. What is the angle between the hands of the clock at 3.45?
Soln: At 3, the angle between the hands = A = 90 deg. In 45 min the hands will move angle of B = 45 X 5.5 deg (since 5.5 deg for 1 min) B = 247.5 deg. Required angle = A ~ B = 157.5 deg. 4. What is the angle between the hands at 4.40?
Soln: At 4 the angle between the hands, A = 120 deg.
In 40 min, B = 40 X 5.5 = 220 deg. The required angle = A ~ B = 100 deg. 5. A clock loses 5 min for every hour and another gains 5 min for every hour. If they are set correct at 10 am on Monday then when will they be 12 hrs apart?
Soln: For every hour watch A loses 5 min and watch B gains 5 min. So for every hour they will differ by 10 min. For 12 hrs (720 min) difference between them the time required = 720 / 10 = 72 hrs So they will be 12 hrs apart after 3 days i.e., at 10 am on Thursday.

Calendars
Here you mainly deal in finding the day of the week on a particular given date. The process of finding this depends on the number of odd days. Odd days are quite different from the odd numbers.
Odd Days: The days more than the complete number of weeks in a given period are called odd days. Ordinary Year: An year that has 365 days is called Ordinary Year. Leap Year: The year which is exactly divisible by 4 (except century) is called a leap year. E.g. 1968, 1972, 1984, 1988 and so on are the examples of Leap Years. 1986, 1990, 1994, 1998, and so on are the examples of non leap years. Note: The Centuries divisible by 400 are leap years. Important Points: An ordinary year has 365 days = 52 weeks and 1 odd day. A leap year has 366 days = 52 weeks and 2 odd days. Century = 76 Ordinary years + 24 Leap years. Century contain 5 odd days. 200 years contain 3 odd days. 300 years contain 1 odd day. 400 years contain 0 odd days. Last day of a century cannot be Tuesday, Thursday or Saturday. First day of a century must be Monday, Tuesday, Thursda y or Saturday. Explanation: 100 years = 76 ordinary years + 24 leap years = 76 odd days + 24 x 2 odd days = 124 odd days = 17 weeks + 5 days 100 years contain 5 odd days. No. of odd days in first century = 5 Last day of first century is Friday. No. of odd days in two centuries = 3 Wednesday is the last day.
No. of odd days in three centuries = 1 Monday is the last day. No. of odd days in four centuries = 0 Sunday is the last day. Since the order is continually kept in successive cycles, the last day of a century cannot be Tuesday, Thursday or Saturday. So, the last day of a century should be Sunday, Monday, Wednesday or Friday. Therefore, the first day of a century must be Monday, Tuesday, Thursday or Saturday.

PROBABILITY Experiment An operation which results in some well-defined outcomes is called an experiment. Random Experiment An experiment whose outcome cannot be predicted with certainty is called a random experiment. In other words, if an experiment is performed many times under similar conditions and the outcome of each time is not the same, then this experiment is called a random experiment. Example: a) Tossing of a fair coin b) Throwing of an unbiased die c) Drawing of a card from a well shuffled pack of 52 playing cards Sample Space The set of all possible outcomes of a random experiments is called the sample space for that experiment. It is usually denoted by S. Example: f) When a die is thrown, any one of the numbers 1, 2, 3, 4, 5, 6 can come up. Therefore. Sample space S = {1, 2, 3, 4, 5, 6} g) When a coin is tossed either a head or tail will come up, then the sample space w.r.t. the tossing of the coin is S = {H, T} h) When two coins are tossed, then the sample space is
Sample point / event point Each element of the sample spaces is called a sample point or an event point. Example: When a die is thrown, the sample space is S = {1, 2, 3, 4, 5, 6} where 1, 2, 3, 4, 5 and 6 are the sample points. Discrete Sample Space A sample space S is called a discrete sample if S is a finite set. Event A subset of the sample space is called an event. Problem of Events Sample space S plays the same role as universal set for all problems related to the particular experiment. is also the subset of S and is an impossible Event. S is also a subset of S which is called a sure event or a certain event. Types of Events A. Simple Event/Elementary Event An event is called a simple Event if it is a singleton subset of the sample space S. Example: a) When a coin is tossed, then the sample space is S = {H, T} Then A = {H} occurrence of head and B = {T} occurrence of tail are called Simple events. b) When two coins are tossed, then the sample space is S = {(H,H); (H,T); (T,H); (T,T)} Then A = {(H,T)} is the occurrence of head on 1st and tail on 2nd is called a Simple event. B. Mixed Event or Compound Event or Composite Event A subset of the sample space S which contains more than one element is called a mixed event or when two or more events occur together, their joint occurrence is called a Compound Event. Example: When a dice is thrown, then the sample space is S = {1, 2, 3, 4, 5, 6} Then let A = {2, 4 6} is the event of occurrence of even and B = {1, 2, 4} is the event of occurrence of exponent of 2 are Mixed events Compound events are of two type: a) Independent Events, and b) Dependent Events C. Equally likely events Outcomes are said to be equally likely when we have no reason to believe that one is more likely to occur than the other Example: When an unbiased die is thrown all the six faces 1, 2, 3, 4, 5, 6 are equally likely to come up. D. Exhaustive Events A set of events is said to be exhaustive if one of them must necessarily happen every time the experiments is performed. Example: When a die is thrown events 1, 2, 3, 4, 5, 6 form an exhaustive set of events. Important We can say that the total number of elementary events of a random experiment is called the exhaustive number of cases.
E. Mutually Exclusive Events Two or more events are said to be mutually exclusive if one of them occurs, others cannot occur. Thus if two or more events are said to be mutually exclusive, if not two of them can occur together. Hence, A1, A2, A3,…, An are mutually exclusive if and only if A iAj = i j Example: a) When a coin is tossed the event of occurrence of a head and the event of occurrence of a tail are mutually exclusive events because we cannot have both head and tail at the same time. b) When a die is thrown, the sample space is S = {1, 2, 3, 4, 5, 6} Let A is an event of occurrence of number greater than 4 i.e., {5, 6} B is an event of occurrence of an odd number {1, 3, 5} C is an event of occurrence of an even number {2, 4, 6} Here, events B and C are Mutually Exclusive but the event A and B or A and C are not Mutually Exclusive. F. Independent Events or Mutually Independent events Two or more event are said to be independent if occurrence or non-occurrence of any of them does not affect the probability of occurrence of or non-occurrence of their events. Thus, two or more events are said to be independent if occurrence or non-occurrence of any of them does not influence the occurrence or non-occurrence of the other events. Example: Let bag contains 3 Red and 2 Black balls. Two balls are drawn one by one with replacement. Let A is the event of occurrence of a red ball in first draw. B is the event of occurrence of a black ball in second draw. then probability of occurrence of B has not been affected if A occurs before B. As the ball has been replaced in the bag and once again we have to select one ball out of 5(3R + 2B) given balls for event B. G. Dependent Events Two or more events are said to be dependent, if occurrence or non-occurrence of any one of them affects the probability of occurrence or non-occurrence of others. Example: Let a bag contains 3 Red and 2 Black balls. Two balls are drawn one by one without replacement. Let A is the event of occurrence of a red ball in first draw B is the event of occurrence of a black ball in second draw. In this case, the probability of occurrence of event B will be affected. Because after the occurrence of event A i.e. drawing red ball out of 5(3R + 2B), the ball is not replaced in bag. Now, for the event B, we will have to draw 1 black ball from the remaining 4(2R + 2B) balls which gets affected due to the occurrence of event A. H. Complementary Events Let S be the sample space for a random experiment and let E be the event. Also, Complement of event E is denoted by E‟ or E, where E‟ means non occurrence of event E. Thus E‟ occurs if and only if E does not occur. n(E) + n(E‟) = n(S) Occurrence of an Event For a random experiment, let E be an event Let E = {a, b, c}. If the outcome of the experiment is either a or b or c then we say the event has occurred. Sample Space : The outcomes of any type Event : The outcomes of particular type Probability of Occurrence of an event Let S be the same space, then the probability of occurrence of an event E is denoted by p(E) and is defined as P(E) = n(E)/n(S) = number of elements in E/number of elements in S P(E) = number of favourable/particular cases total number of cases Example:
a) When a coin is tossed, then the sample space is S = {H, T} Let E is the event of occurrence of a head E = {H} b) When a die is tossed, sample space S = {1, 2, 3, 4, 5, 6} Let A is an event of occurrence of an odd number And B is an event of occurrence of a number greater than 4 A = {1, 3, 5} and B = {5, 6} P(A) = Probability of occurrence of an odd number = n(A)/n(S) = 3/6 = ½ and P(B) = Probability of occurrence of a number greater than 4 = n(B)/n(S) = 2/6 = 1/3 EXERCISE Questions 1 – 7 A coin is flipped three.

Critical Reasoning Exercise 1: 1. Recent studies have highlighted the harmful effects of additives in food (colors, preservatives, flavor enhancers etc.). There are no synthetic substances in the foods we produce at Munchon Foods – we use only natural ingredients. Hence you can be sure you are safeguarding your family‟s health when you buy our products. Which of the following, if true, would most weaken the contention of Munchon Foods?
A. Some synthetic substances are not harmful B. Some natural substances found in foods can be harmful C. Food without additives is unlikely to taste good D. Munchon Foods produces only breakfast cereals E. Without preservatives some foods could cause harm 2. A fruit known as amla in certain parts of Asia is an excellent source of vitamin C. A small quantity of the fruit grated and added to salads provides almost all the daily requirement of this vitamin. However, the fruit is very sour. A new process designed to remove most of the sour taste will make the fruit acceptable to American tastes. We are therefore starting to grow this fruit for sale in the United States. The argument above assumes all of the following except A. Americans generally won‟t eat very sour foods B. The new process does not remove a significant part of the vitamin content C. That a market exists for a new source of vitamin C D. The fruit can be used only in salads E. Apart from being sour there are no other objections to eating this fruit 3. Most scientists agree that new lines of interdisciplinary research are the need of the hour. Even government committees on science have stressed the need for more interdisciplinary projects. Yet, of ten proposals for new interdisciplinary projects last year, only one was successfully funded. Some have suggested that this means that as yet researchers are not coming up with sufficiently persuasive projects, or that their proposals are not of high enough quality, or even that the reputations of these researchers is not high enough. However, the real reason probably lies in the way funding is organized. Funding is still allocated according to the old categories and there are no funds specifically for research that overlaps different subject areas. The two parts in bold-face are related to each other in which of the following ways? A. The first is a finding that the author finds unacceptable; the second is the author‟s own position B. The first is a finding that the author attempts to account for; the second is a finding that contradicts the author‟s main conclusion. C. The first is a fact that the author attempts to account for. The second is data that explicitly supports the author‟s main conclusion. D. The first is a position that the author opposes; the second is the author‟s main position. E. The first is a situation that the author finds paradoxical; the second is an assumption that the author uses to reinforce the paradox.

Barbie: It is in the interest of the real estate agent to get me the best price for my property because he gets a commission based on the selling price. Therefore, when selling my house I will certainly use an agent rather than trying to sell the house by word of mouth, or by advertising in newspapers or on the internet. Barbie‟s could strengthen her position by pointing out all of the following except A. Houses of comparable value often obtain a lower price when sold on the internet B. Very few houses are sold on the internet at the moment an so a valid comparison is difficult C. The agent‟s service includes many add-on benefits in terms of legal fees, surveyor‟s reports and advice that are not available on internet sites D. Some buyers pay the agent to find them a cheap house E. The agent‟s commission is usually less than the difference between the internet price and the higher price the agent obtains for you 5. Early data on seat-belt use showed that seat-belt wearers were less likely to be killed in road accidents. Hence, it was initially believed that wearing a seat-belt increased survival chances in an accident. But what the early analysts had failed to see was that cautious drivers were more likely to wear the belts and were also less likely to cause „big accidents‟, while reckless drivers were more likely to be involved in „big‟ accidents and were less likely to wear the belts. Which of the following, if true, could an opponent of the view presented above best cite as a reason for recommending continued use of seat-belts? A. Careful drivers who are involved in accidents caused by reckless drivers, would be more likely to survive if wearing a belt B. All drivers should be required by law to wear a belt C. The ratio of „big‟ to „small‟ road accidents is very small D. In fatal accidents seat-belt wearers in the front seat are less likely to survive than those wearing seat belts in the back seat E. On average, careful drivers pay lower insurance premiums than do drivers who have been involved in accidents. 6. French cuisine is highly regarded all over the world. Yet in Paris there are more American restaurants selling burgers and fries (which many people now class as „junk food‟) than there are in any other European capital city. Obviously the French are very fond of „junk food‟, and are not too proud to eat it. Which of the following, if true, would most weaken the author‟s contention?
A. There are also a larger number of Lebanese restaurants in Paris than there are in other European capital cities B. French Cordon Bleu cuisine is very expensive C. The number of French tourists eating in New York burger restaurants is very low D. Junk food is actually has high nutritional value when eaten in moderation E. There are an unusually large number of American tourists in Paris who eat at burger joints 7. Scientists investigating a rare metabolic disorder hypothesized that obesity was a predisposing factor in the development of the disease. A study of twenty patients found that, on average, the patients were close to the normal weight for their height. Before concluding that obesity is not a predisposing factor, the researchers would find the answer to which of the following questions most useful? A. Are the patients above or below normal height? B. Were any of the patients underweight when the disorder was diagnosed? C. Does weight loss reduce the severity of the symptoms? D. Have the patients always been close to the normal weight for their heights? E. How many of the patients had obese parents? 8. In research designed to investigate the possibility of animals developing friendship with other, unrelated, members of their species, a group of 29 chimpanzees were reared together for 15 years. At the end of that time the chimps were presented with two options for obtaining food: press a lever and feed themselves, or press another identical lever and feed themselves, and at the same time deliver food to the chimp next door. (The chimps were able to see each other). The researchers found that the chimps were no more likely to choose the lever that fed a neighbor. The researchers concluded that the chimps had no concept of friendship. However, one critic has suggested that the animals were in an artificial environment from which little can be concluded, and that, at the least, the test ought to have involved the animals being able to touch. What role do the parts in boldface play in the argument above? A. The first is a position that the critic opposes. The second is a position that the critic supports. B. The first is an observation that supports the researchers‟ position. The second is an observation that opposes the researchers‟ position. C. The first is a finding on which the researchers base their conclusion. The second is a suggestion that might cast doubt on that finding. D. The first is an observation that supports the critic‟s conclusion. The second is the critic‟s conclusion. E. The first is part of the evidence that the critic disputes. The second is a suggestion that the researchers do not accept.
9. Questions 9-10 refer to the following: Jay: We have too many people working on each of our computers in the office. The high frequency of breakdowns is due to too many people handling the same hardware. Ada: We have just as many people working in our office, yet we hardly need any repairs to our systems. Our systems must be more robust than yours. Ada‟s argument would be most strengthened by providing data on the A. actual number of people in the two offices B. type of computers that are in both offices C. ratio of computers to users in her office D. number of visits by computer engineers to service the computers in Jay‟s office E. number of computers in Jay‟s office 10. Refer to the extract in the previous question Jay apparently believes that A. he has the best available hardware B. the frequency of breakdowns in his office is above average C. software specifications are not important in his office D. no other office has a similar ratio of computers to users E. he does not need more people working in his office 11. A rare disease, malicitis, is being diagnosed with increasing frequency. The number of cases reported this year is more than double the number reported four years ago. The government should now allocate more funds for treatment and prevention of malicitis. All of the following, if true, would weaken the conclusion except A. funds already available for research in malicitis are currently under-utilized B. a new test employed for the first time this year detects malicitis at a considerably earlier stage in the development of the disease C. the number of cases reported this year represents the same fraction of the population as reported in all of the last five years D. a committee of experts reviewed the funding four years ago E. a private foundation has committed sufficient funds to cover treatment and prevention needs as well as research for the next five years
12. Thousands of people have tonsillectomies every year and all live normal lives after the operation. We can conclude, from this observation, that the tonsils have no function in the body. The argument would be most weakened by which of the following, if it were true? A. People live normal lives after appendectomies but the appendix is known to be part of the digestive system. B. Another part of the body can take over the function of the tonsils if they are removed. C. The tonsils have been shown to have a vital role to play in the physiology of laboratory rabbits and guinea pigs. D. The human tonsil develops as part of the immune system, a system of vital importance in defense against disease. E. Tonsillectomies are performed only when the tonsils become seriously infected. 13. Photography is no longer an art form. Nowadays everyone has access to digital cameras that only need to be pointed at the subject in order to generate a perfect image. The writer of the argument apparently assumes that A. the selection of the subject is not an important artistic factor in photography B. digital cameras will continue to improve in quality C. digital cameras can never go wrong D. photography with all other types of camera is an art form E. art is not perfect 14. The enormous distances between stars are not spaces entirely devoid of matter. The interstellar spaces are filled with ‘dust’: very low density matter. This miniscule amount of matter, spread over almost infinite distances, acts like a curtain obscuring the stars that lie behind. If it were not for this material we would see no dark patches in the sky at night: the sky would be entirely covered with stars. The two parts in boldface play what roles in the argument above? A. The first is a suggestion that the author wishes to dispute. The second is hypothesis that the author wishes to explain. B. The first is the main point the author wishes to make. The second is a hypothetical result of accepting that point. C. The first is a fact that the author thinks is important in explaining a certain phenomenon. The second is a result that the author would expect if that fact were not true.
D. The first is a speculation that the author wishes to justify. The second is a consequence that would result if that speculation is not true. E. The first is an established fact that the author wishes to explain. The second is a consequence of accepting this fact. 15. The number of people diagnosed with dengue fever (which is contracted from the bite of an infected mosquito) in North India this year is twice the number diagnosed last year. The authorities have concluded that measures to control the mosquito population have failed in this region. All of the following, if true, would cast doubt on the authorities‟ conclusion except A. more cases are now reported because of increases in administrative efficiency B. a very high proportion of the cases were in people who had recently returned from neighboring countries C. an effective diagnostic test was introduced about nine months ago D. the disease is prevalent only in some industrialized areas which have shown a dramatic increase in population due to migration E. the incidence (number of cases per thousand) of malaria, also contracted from mosquito bites, has increased 16. Questions 16-17 refer to the following: In a recent study of responses to visual images, researchers found that women most frequently gave the rating „most attractive‟ to images of male faces that were more feminine in contour, and rated more masculine faces, on average, „less attractive‟. The researchers concluded that modern women prefer men who are less obviously masculine in their facial features. The conclusion would be most severely weakened if which of the following were true? A. Facial features are not the criterion that most women use to decide whether a man is attractive. B. The visual images were computer generated composites of photographs and not pictures of actual men. C. The rating scale was a ten point scale with most attractive scoring 1-2 and least attractive scoring 8-10. D. Most popular male actors have the features that the study allocated to the more masculine category. E. The faces with the more masculine features were all significantly older than those with the feminine features. 17. Refer to the extract in the previous question
Which is the following is an assumption that the researchers apparently made in this study? A. The women who participated in the study were sufficiently representative of modern women in general. B. Male faces are, in general, attractive to women. C. Visual images are important to women. D. It is impossible to predict what features an ideal face would have. E. Women in previous ages would have preferred more masculine men. 18. Red is a color which has powerful effects on human beings as well as animals. A group of psychologists carried out an experiment which confirms the subconscious effects of this color on human behavior. They provided selected sports teams at school and college level with either red or blue shorts and recorded the outcome of the games. The teams wearing red won in a disproportionate number of matches. The psychologists suggested that either the teams wearing red subconsciously felt themselves more powerful, or that the non-red teams were subconsciously intimidated by the red color. Which of the following, if true, would most weaken the psychologists‟ suggestion? A. Each team wore red in some matches and blue in others. B. The color blue has the subconscious effect of making human beings less competitive. C. The effect was only observed if all the team members wore white shirts. D. Red signifies danger in some cultures whereas it signifies happiness in others. E. In a subsequent study, teams with all-red outfits were more likely to report that they thought they would win no matter what color the opponents wore. 19. It is often thought that our own modern age is unique in having a large number of people who live into old age. It has frequently been assumed that plagues, wars, and harsh working conditions killed off most people in previous ages before they could reach old age. However, recent research shows that in 17th century Europe, for example, people over sixty comprised 10 percent of the population. The studies also revealed that although infant mortality remained high until the 20th century in Europe, people who survived to adulthood could expect to live to be old. The portions in boldface play which of the following roles in the argument above? A. The first is a conclusion that the author supports. The second is data that contradicts that conclusion. B. The first is a finding that the author contests. The second is a finding that the author accepts.
C. The first is an assumption that the author thinks is invalid. The second is data that validates that assumption. D. The first is a position that the author opposes. The second is a finding that supports the author‟s position. E. The first is a position that the author opposes. The second is an assumption which, if valid, negates the author‟s view. 20. A marriage counselor noted that couples who have occasional violent arguments are less likely to divorce within the next six months than those who have frequent but less violent arguments. He concluded that frequent arguing is a major factor in the causation of severe marital disharmony. The counselor‟s conclusion is most weakened by which of the following observations? A. Couples who have already come to the point of divorce argue continuously over small matters. B. People who have recently divorced are more likely to argue violently when they meet. C. Many people in happy marriages have occasional violent arguments. D. Recently divorced people rarely cite frequent arguments as a cause of marital disharmony E. A significant fraction of couples close to divorce do not talk to each other. 21. The Dean claimed that, as a result of continued cutbacks in the budget for pure science research, fewer students are choosing a career in physics, and therefore the number of postgraduate students studying physics is likely to decline. Which of the following, if true, casts most doubt on the Dean‟s conclusion? A. The number of students majoring in physics at the undergraduate level has been increasing steadily over the years, a trend that is expected to continue. B. The number of students studying chemistry declined even before cutbacks in research funding were noted. C. Most postgraduate students of physics move to careers in computer science and engineering. D. The Dean‟s own university has recently increased the number of staff members teaching physics. E. The budget cutbacks are less severe for the pure sciences than for applied sciences. 22. A nature conservancy expert found little support for his campaign to protect toads. He suggested that, even thought the campaign highlighted the vital role the toads played in the ecology of the region, people were unenthusiastic about saving toads as these animals are perceived as unpleasant creatures, and people seldom feel passionate about animals with which they have no positive feelings.
The expert‟s opinion would be most strengthened by which of the following observations? A. Ecological conservation is an increasingly important concern in the region. B. A recent campaign to save bats achieved a measure of success only after a cartoon bat was adopted as the mascot of the local football team. C. Snakes and lizards also need protection in this region as a result of human activity. D. The campaign to protect toads has been in existence for over five years and yet the toad population continues to decline. E. The children in the local schools were found to have a greater aversion to toads than to snakes. 23. Many people report that exposure to certain foods such as cheese, red wine, and chocolate, are associated with the onset of migraine headaches. Other people report that exposure to certain smells (especially strong perfumes) seems to trigger a migraine headache, and some note that exposure to bright and flickering lights can be followed by a migraine. It would seem that a person with a tendency to get migraines should try to find which of these situations is associated with the onset of the headache and then avoid this stimulus. All of the following, if true, would indicate potential problems with the recommendation above except A. the time delay between the trigger and the onset of the headache can make it exceptionally difficult to identify the trigger B. the presence of a known trigger doesn‟t always cause a migraine C. in many cases an internal hormonal change triggers a migraine D. in a high proportion of cases the patients report multiple triggers for their headaches E. most of the known triggers are common and almost unavoidable features of modern life 24. It is strange that in Sentacity there are so many corner shops selling food items. After all there are many supermarkets in the city which sell food at cheaper prices, and many of these supermarkets are open 24-hours. Which of the following, if true, would be of least help in explaining the paradoxical observation? A. The corner shops are selling specialist food items not available in the supermarkets. B. The supermarkets are mostly located on the outskirts of the city and require residents to use cars or public transport to reach them.
C. The main business of the local shops is newspaper distribution and food items represent a small part of their turnover. D. The corner shops are mainly family-owned businesses and have been there for much longer than the supermarkets and are perceived as an important feature of the community. E. The corner shops are willing to make home deliveries.
Exercise 2: 1. Fact 1: Television advertising is becoming less effective: the promotion of brand names promoted on television that viewers of the advertising can recall is slowly decreasing. Fact 2: Television viewers recall commercials aired first or last in a cluster of consecutive commercials far better than they recall commercials aired somewhere in the middle. Fact 2 would be most likely to contribute to an explanation of fact 1 if which of the following were also true? a. The total time allotted to the average cluster of consecutive television commercials is decreasing. b. The average number of clusters of consecutive commercials per hour of television is increasing. c. The average number of hours per day that people spend watching television is decreasing. d. The average number of television commercials in a cluster of consecutive commercials is increasing. e. The average television viewer currently recalls fewer than half the brand names promoted in commercials he or she saw. 2. The average normal infant born in the United States weighs between twelve and fourteen pounds at the age of three months. Therefore, if a three-month-old child weighs only ten pounds, its weight gain has been below the United States average. Which of the following indicates a flaw in the reasoning above? a. The phrase "below average" does not necessarily mean insufficient. b. Average weight gain is not the same as average weight. c. Some three-month old children weigh as much as seventeen pounds. d. It is possible for a normal child to weigh ten pounds at birth. e. Weight is only one measure of normal infant development.
3. Which of the following best completes the passage below? People buy prestige when they buy a premium product. They want to be associated with something special. Mass-marketing techniques and price-reduction strategies should not be used because ___________ . a. continued sales depend directly on the maintenance of an aura of exclusivity b. expansion of the market niche to include a broader spectrum of consumers will increase profits c. manufacturing a premium brand is not necessarily more costly than manufacturing a standard brand of the same product d. affluent purchasers currently represent a shrinking portion of the population of all purchasers e. purchasers of premium products are concerned with the quality as well as with the price of the products 4. Which of the following best completes the passage below? In a survey of job applicants, two-fifths admitted to being at least a little dishonest. However, the survey may underestimate the proportion of job applicants who are dishonest, because _____. a. some generally honest people taking the survey might have claimed on the survey to be dishonest b. some people who claimed on the survey to be dishonest may have been answering honestly c. some people who claimed on the survey to be at least a little dishonest may be very dishonest d. some dishonest people taking the survey might have claimed on the survey to be honest e. some people who are not job applicants are probably at least a little dishonest
5. A program instituted in a particular state allows parents to prepay their children's future college tuition at current rates. The program then pays the tuition annually for the child at any of the state's public colleges in which the child enrolls. Parents should participate in the program as a means of decreasing the cost of their children's college education. Which of the following, if true, is the most appropriate reason for parents not to participate in the program? a. The prepayment plan would not cover the cost of room and board at any of the state's public colleges.
b. The amount of money accumulated by putting the prepayment funds in an interest-bearing account today will be greater than the total cost of tuition for any of the public colleges when the child enrolls. c. Some of the state's public colleges are contemplating large increases in tuition next year. d. The annual cost of tuition at the state's public colleges is expected to increase at a faster rate than the annual increase in the cost of living. e. The parents are unsure about which public college in the state the child will attend. 6. Most consumers do not get much use out of the sports equipment they purchase. For example, seventeen percent of adults in the United States own jogging shoes, but only forty-five percent of the owners jog more than once a year, and only seventeen percent jog more than once a week. Which of the following, if true casts most doubt on the claim that most consumers get little use out of the sports equipment they purchase? a. Many consumers purchase jogging shoes for use in activities other than jogging. b. Joggers who jog more than once a week are often active participants in other sports as well. c. Consumers who take up jogging often purchase an athletic shoe that can be used in other sports. d. Joggers are most susceptible to sports injuries during the first six months in which they jog. e. Joggers often exaggerate the frequency with which they jog in surveys designed to elicit such information. 7. It is true that it is against international law to sell plutonium to countries that do not yet have nuclear weapons. But if United States companies do not do so, companies in other countries will. Which of the following is most like the argument above in its logical structure? a. It is true that it is illegal for a government official to participate in a transaction in which there is an apparent conflict of interest. But if the facts are examined carefully, it will clearly be seen that there was no actual conflict of interest in the defendant's case. b. It is true that it is against the police department's policy to negotiate with kidnappers. But if the police want to prevent loss of life, they must negotiate in some cases. c. It is true that it is against the law to burglarize people's homes. But someone else certainly would have burglarized the house if the defendant had not done so first. d. It is true that company policy forbids supervisors to fire employees without two written warnings. But there have been many supervisors who have disobeyed this policy.
e. It is true that it is illegal to refuse to register for military service. But there is a long tradition in the United States of conscientious objection to serving in the armed forces. 8. Neither a rising standard of living nor balanced trade, by itself, establishes a country's ability to compete in the international marketplace. Both are required simultaneously since standards of living can rise because of growing trade deficits and trade can be balanced by means of a decline in a country's standard of living. If the facts stated in the passage above are true, a proper test of a country's ability to be competitive is its ability to a. keep its standard of living constant while trade deficits rise. b. balance its trade while its standard of living rises. c. balance its trade while its standard of living falls. d. increase trade deficits while its standard of living rises. e. decrease trade deficits while its standard of living falls. 9. The program to control the entry of illegal drugs into the country was failure in 1987. If the program had been successful, the wholesale price of most illegal drugs would not have dropped substantially in 1987. The argument in the passage depends on which of the following assumptions? a. The price paid for most illegal drugs by the average consumer did not drop substantially in 1987. b. The supply of illegal drugs dropped substantially in 1987. c. The wholesale price of a few illegal drugs increased substantially in 1987. d. Domestic production of illegal drugs increased at a higher rate than did the entry of such drugs into the country. e. A drop in demand for most illegal drugs in 1987 was not the sole cause of the drop in their wholesale price. 10. The program to control the entry of illegal drugs into the country was failure in 1987. If the program had been successful, the wholesale price of most illegal drugs would not have dropped substantially in 1987. The argument in the passage would be most seriously weakened if it were true that a. in 1987 smugglers of illegal drugs, as a group, had significantly more funds at their disposal than did the country's customs agents. b.domestic production of illegal drugs increased substantially in 1987. c. in 1987 illegal drugs entered the country by a different set of routes than they did in 1986. d. the author's statements were made in order to embarrass the officials responsible for the drug-control program. e. the country's citizens spent substantially more money on illegal drugs in 1987 than they did in 1986.
11. Hardin argued that grazing land held in common (that is, open to any user) would always be used less carefully than private grazing land. Each rancher would be tempted to overuse common land because the benefits would accrue to the individual, while the costs of reduced land quality that results from overuse would be spread among all users. But a study comparing 217 million acres of common grazing land with 433 million acres of private grazing land showed that the common land was in better condition. The answer to which of the following questions would be most useful in evaluating the significance, in relation to Hardin's claim, of the study described above? a. Was the private land that was studied of comparable quality to the common land before either was used for grazing? b. Did any of the ranchers whose land was studied use both common and private land? c. Were the users of the common land that was studied at least as prosperous as the users of the private land? d. Did the ranchers whose land was studied tend to prefer using common land before either was used for grazing? e. Were there any owners of herds who used only common land, and no private land for grazing. 12. Hardin argued that grazing land held in common (that is, open to any user) would always be used less carefully than private grazing land. Each rancher would be tempted to overuse common land because the benefits would accrue to the individual, while the costs of reduced land quality that results from overuse would be spread among all users. But a study comparing 217 million acres of common grazing land with 433 million acres of private grazing land showed that the common land was in better condition. Which of the following, if true and known by the ranchers, would best help explain the results of the study? a. With private grazing land, both the costs and the benefits of overuse fall to the individual user. b. An individual who overuses common grazing land might be able to achieve higher returns than other users can, with the result that he or she would obtain a competitive advantage. c. The cost in reduced land quality that is attributable to any individual user is less easily measured with common land than it is with private land. d. If one user of common land overuses it even sightly, the other users are likely to do so even more, with the consequence that the costs to each user outweigh the benefits. e. there are more acres of grazing held privately than there are held in common. 13. In Los Angeles, a political candidate who buys saturation radio advertising will get maximum name recognition.
The statement above logically conveys which of the following?
A. Radio advertising is the most important factor in political campaigns in Los Angeles. B. Maximum name recognition in Los Angeles will help a candidate to win a higher percentage of votes cast in the city. C. Saturation radio advertising reaches every demographically distinct sector of the voting population of Los Angeles. D. For maximum name recognition a candidate need not spend on media channels other than radio advertising. E. A candidate's record of achievement in the Los Angeles area will do little to affect his or her name recognition there. 14. The rate of violent crime in this state is up 30 percent from last year. The fault lies entirely in our court system: Recently our judges' sentences have been so lenient that criminals can now do almost anything without fear of a long prison term. The argument above would be weakened if it were true that
a. 85 percent of the other states in the nation have lower crime rates than does this state. b. white collar crime in this state has also increased by over 25 percent in the last year. c. 35 percent of the police in this state have been laid off in the last year due to budget cuts. d. polls show that 65 percent of the population in this state oppose capital punishment. e. the state has hired 25 new judges in the last year to compensate for deaths and retirements. 15. The increase in the number of newspaper articles exposed as fabrications serves to bolster the contention that publishers are more interested in boosting circulation than in printing the truth. Even minor publications have staffs to check such obvious fraud. The argument above assumes that
a. newspaper stories exposed as fabrications are a recent phenomenon. b. everything a newspaper prints must be factually verifiable. c. fact checking is more comprehensive for minor publications than for major ones. d. only recently have newspapers admitted to publishing intentionally fraudulent stories. e. the publishers of newspapers are the people who decide what to print in their newspapers. 16. Bill earns more commission than does Sandra. But since Andrew earns more commission than does Lisa, it follows that Bill earns more commission than does Lisa.
Any of the following, if introduced into the argument as an additional premise, makes the argument above logically correct EXCEPT:
a. b. c. d. e.
Andrew earns more commission than Bill Sandra earns more commission than Lisa Sandra earns more commission than Andrew Sandra and Andrew earn the same amount of commission Bill and Andrew earn the same amount of commission 17. During the SARS days, about 23,500 doctors who had treated SARS sufferers died and about 23,670 doctors who had not engaged in treatment for SARS sufferers died. On the basis of those figures, it can be concluded that it was not much more dangerous to participate in SARS treatment during the SARS day than it was not to participate in SARS treatment. Which of the following would reveal most clearly the absurdity of the conclusion drawn above?
a. Counting deaths among doctors who had participated in SARS treatment in addition to deaths among doctors who had not participated in SARS treatment b. Expressing the difference between the numbers of deaths among doctors who had treated SARS sufferers and doctors who had not treated SARS suffers as a percentage of the total number of deaths c. Separating deaths caused by accidents during the treatment to SARS suffers from deaths caused by infect of SARS suffers. d. Comparing death rates per thousand members of each group rather than comparing total numbers of deaths e. Comparing deaths caused by accidents in the United States to deaths caused by infect in treating SARS suffers. 18. In 2003 an airline in United State lost more than half, on average, of the foreign passengers they had previously served each year. Researchers have alleged that this extreme drop resulted from a rise in price of tickets for international lines from $60 to $90 per 1,000 miles. Which of the following, if feasible, offers the best prospects for alleviating the problem of the drop in passengers as the researchers assessed it?
a. Cooperating with other airlines to provide more international lines. b. Allowing foreign passengers to pay the same as the previous international line c. Reemphasizing the goals and mission of the airline as serving both domestic passengers and foreign passengers d.

Cubes
Examples Directions: A cube is coloured red on all faces. It is cut into 64 smaller cubes of equal size. Now, answer the following questions based on this statement. Example 1. How many cubes have no face coloured? (a) 24 (b) 8 (c) 0 (d) 16 Example 2. How many cubes are there which have only one face coloured? (a) 4 (b) 16 (c) 24 (d) 8 Example 3. How many cubes have two red opposite face? (a) 8 (b) 16 (c) 24 (d) 0 Example 4. How many cubes have three faces coloured (a) 16 (b) 24 (c) 4 (d) 8 Solution. The given figure shows the cube coloured real on all faces, and divide into 64 smaller cubes.
Here
n = Side of big cube/Side of small cube = 4/1 = 4
1. Number of smaller cubes with no surface painted = (n – 2)3 = (4 – 2)3 = 23 = 8 2. Number of smaller cubes with one surface painted (n – 2)2 × 6 = (4 – 2)2 × 6 = 22 × 6 = 24
3. Number of smaller cubes with two surface painted = (n – 2) × 12 = (4 – 2) × 12 2 × 12 = 24 4. Number of smaller cubes with three surfaces painted = 8
Exercise 20 Directions: A wooden cube is painted blue on all the four adjoining sides and green on two opposite sides, i.e., top and bottom.

Logical Deductions Types of statements: The statements can be divided into four categories depending on their sense. They are 1. General 2. Particular 3. Negative and
4. Particular Negative A general statement starts with a word “all” or “every” or “each” Eg: All x are y. Every x is y. A particular statement focuses on a particular group or sector. It normally starts with “some”, “many”, “most” or a name. Eg: Some x are y. Many x are y. Sachin is good. A negative statement contains a negative word like “no” or “not”. Eg: No x is y. All y are not x. A particular negative statement combine both the features of particular and negative statement. Eg: Some x are not y. Many y are not z. Sachin is not good. Distribution: When “All x are y” is given we can say that all the points of set x belong to y but we cant define such a property common to all the points of y. In other words we can say a property common to all points of x but not y. Then it is said that “x” is distributed but “y” is not. In “All x are y”, x becomes the subject and y becomes the object. So, a general statement distributes only the subject but not the object. Similarly, a particular statement distributes neither subject nor the object. A negative statement distributes both the subject and the object. A particular statement distributes the object but not the subject. In short, the distribution can be said as follows: General statement: Subject – Yes Particular Statement: Subject – No Negative Statement: Subject – Yes Particular Negative: Subject – No
Object Object Object Object
– – – –
No No Yes Yes
Deriving a deduction: When two statements are given to you, your duty is to derive a deduction that logically follows both the statements logically. For this we will make use of the distribution. The process of deriving a conclusion is as follows:
Step 1: Identify the common term for both the statements. If no common term is present the no deduction can be derived. Step 2: Apply the distribution properties to subjects and objects depending on the type of the statement. Rule: If and only if the common term is having the distribution only once, then the deduction can be derived. Else there can be no deduction. Eg: All x are y. All x are z. Soln: Common term : x In first statement and the second statement, x is distributed (since x is subject in both). So the common term has 2 distributions => no deduction follows. Step 3: When you decide that there is a deduction possible then read out all the words present in the two statements excluding the common term and repeated words, from left to right. Eg: All x are y. All y are z. Soln: Common term: y. It is distributed only once (in second statement). So a deduction can follow. It is All x are z. (Excluding y and repeated words). Rule: Particularity and negation are called special properties and if any statement contains a special property the same should be followed by the conclusion also. Eg: Some x are y. All y are z. Soln: Common term: y. It is distributed only once (in second statement). So a deduction follows. It is Some x are z. (Here some is a special property and so conclusion also follows the same. Common term is excluded.) Rule: For two particular or negative statements there can be no conclusion. Examples: 1. All x are y. All z are y. Soln: No conclusion follows. (since common term y is not distributed at all) 2. All x are y. Some y are z. Soln:
No conclusion since common term y is not distributed at all. 3. All x are y. No y is z. Soln: No x is z (or) No z is x. (Since No is a special property) 4. Some x are y. No y is z. Soln: Some x are not z. (Since some and not are special properties and so should be present in conclusion).

2. Line Graph: A line graph indicates the variation of a quantity w.r.t two parameters calibrated on X and Y-axis respectively. Note: 1. Any part of the line graph parallel to X-axis represents no change in the value of Y parameter w.r.t the value of X parameter. 2. The steepest or maximum part of the line graph indicates maximum percentage change of the value during the two consecutive period in which the related part lies. 3. If the steepest part is a rise slope, then it is the highest percentage growth. 4. If the steepest part is a decline slope, it will represent a maximum percentage fall of the value calibrated in the other axis. 3. Bar Graph: Bar graphs are diagrammatic representation of a discrete data. Types of Bar Graphs: o
Simple Bar Graphs: A simple bar graph relates to only one variable. The values of the variables may relate to different years or different terms.
o
Sub-divided Bar Graph: It is used to represent various parts of sub-classes of total magnitude of the given variable.
o
Multiple Bar Graphs: In this type, two or more bars are constructed adjoining each other, to represent either different components of a total or to show multiple variables.
4. Pie Chart: In this method of representation, the total quantity is distributed over a total angle of 360o which is one complete circle or pie. Note: Here, the data can be plotted w.r.t only one parameter.

Data Sufficiency Data sufficiency questions appear in the ANALYTICAL section of the exam.. These questions require knowledge of the following topics: Arithmetic Elementary algebra Commonly know concepts of geometry Data sufficiency questions are designed to measure your ability to analyze a quantities problem, recognize which given information is relevant, and determine at what point there is sufficient information to solve a problem. In these questions, you are to classify each problem according to the five or four fixed answer choice, rather than find a solution to the problem. Each Data sufficiency question consists of a question, often accompanied by some initial information, and two statements, labeled (1) and (2), which contain additional information. You must decide whether the information in each statement is sufficient to answer the question or- if neither statement provides enough information –whether the information in the two statements together is sufficient. It is also possible that the statements in combination do not give enough information answer the question. Begin by reading the initial information and the question carefully. Next, consider the first statement. Does the information provided by the first statement is sufficient to answer the question? Go on the statement. Try to ignore the information given in the first statement when you consider the second statement. Now you should be able to say, for each statement, whether it is sufficient to determine the answer. Next, consider the two statements in tandem. Do they, together, enable you to answer the question? Give our answers as per the following statements A statement (1) alone is sufficient but statement (2) alone is not sufficient
B statement (2) alone is sufficient but
statement (1) alone is not sufficient

Venn Diagrams The term venn Diagram relates to the different type of figures drawn to represent relationship between two or more objects. These figures represent by a circle, triangle, square and rectangle. The concept of venn diagram originates from set theory. A basis concept of set, subset, disjoint set can help to understand the concept of venn diagram. To understand these terms, we are given following points with examples. Example 1. An object is said to have an intersection with the other object, when two objects share something in common. For Examples:
(a) Dogs, Pets (b) Fathers, Brothers (c) Clerks, Government Employees Example 2. An object is said to be a subset of another object, if former is a part of latter. For examples:
(a) Minutes, Hours (b) Females, Mothers (c) Engineers, Human Beings Example 3. An object is said to be disjoint with other, when two objects share nothing in common. For examples:
(a) Table, Chair (b) Doctors, Engineers (c) Human Beings, Rates
Directions (Qs. 1-4) : Each of the se questions below contains three group of things. You are to choose from the following fine numbered diagrams, a diagram that depicts the correct relationship among the three groups of things in each questions.

(a) (b) (c) (d)
Animals, Insects, Cockroaches Country, States, Districts Animals, Mates, Females and Hermaphrodities States Districts, Union Territory
Solution (d). Districts from the part of the state but, union territory is entirely different.
Example 7. In the following diagram, the square represents girls, the circle represents tall persons, the triangle is for tennis players and the rectangle stands for the swimmers. On the basis of the above diagram, answer the following questions.
1. Which letter represents tall girl, who do not play tennis and are not swimmers? (a) E (b) G (c) D (d) C
2. Which letter represents girls who are swimmers, play tennis but are not tall? (a) F (b) B (c) E (d) None of these 3. Which letter represents tall persons who are gents and swimmers but do not play tennis? (a) J (b) K (c) L (d) I 4. Which letter represents tall girls who are swimmers but don‟t play tennis? (a) H (b) G (c) D (d) C SOLUTION 1. (c). Tall girls are represented by the region common to the square and the circle i.e., D, C, G, and H. But according to the given conditions, the girls are neither a part of rectangle nor the triangle. So, Answer is D. 2. (d). Girls, who are swimmers and play tennis are represented by the region i.e., H. But according to the given condition girls should not be tall. So, required region should not be a part of the circle. Since, it is a part of the circle, hence the answer is none of these. 3. (b). Tall persons are represented by regions inside the circle i.e., C, D, G, H, I, J and K. Since persons are not girls and do not play tennis, so the region should not be a part of either the square or the triangle. So, C, D, G, H should be excluded. Also according to the given conditions, the persons should be swimmers. So, the required region should be a part of the rectangle. Hence, the answer is K. 4. (b). Tall girls who are swimmers are represented by the region common to the square, circle and the rectangle i.e., G and H. But according to the given conditions, girls should not be tennis players. So, the required region should not be apart of the triangle, so H should be excluded. Hence, the answer is G. Example 8. Read the figure and find the region representing persons who are educated and employed but not confirmed. (a) b, d (b) a, b, c (c) a, c (d) a, d, c
Solution (a). The required region is the one which is common to the circles but lies outside the triangle. So the answer is b and d.

Reading Comprehension Exercise 1: In the sixteenth century, an age of great marine and terrestrial exploration, Ferdinand Magellan led the first expedition to sail around the world. As a young Portuguese noble, he served the king of Portugal, but he became involved in the quagmire of political intrigue at court and lost the king's favor. After he was dismissed from service to the king of Portugal, he offered to serve the future Emperor Charles V of Spain. A papal decree of 1493 had assigned all land in the New World west of 50 degrees W longitude to Spain and all the land east of that line to Portugal. Magellan offered to prove that the East Indies fell under Spanish authority. On September 20, 1519, Magellan set sail from Spain with five ships. More than a year later, one of these ships was exploring the topography of South America in search of a water route across the continent. This ship sank, but the remaining four ships searched along the southern peninsula of South America. Finally they found the passage they sought near a latitude of 50 degrees S. Magellan named this passage the Strait of All Saints, but today we know it as the Strait of Magellan. One ship deserted while in this passage and returned to Spain, so fewer sailors were privileged to gaze at that first panorama of the Pacific Ocean. Those who remained crossed the meridian we now call the International Date Line in the early spring of 1521 after ninety-eight days on the Pacific Ocean. During those long days at sea, many of Magellan's men died of starvation and disease. Later Magellan became involved in an insular conflict in the Philippines and was killed in a tribal battle. Only one ship and seventeen sailors under the command of the Basque navigator Elcano survived to complete the westward journey to Spain and thus prove once and for all that the world is round, with no precipice at the edge. 1. The sixteenth century was an age of great ___exploration. A. cosmic B. land C. mental D. common man E. none of the above 2. Magellan lost the favor of the king of Portugal when he became involved in a political ___. A. entanglement B. discussion C. negotiation D. problems E. none of the above 3. The Pope divided New World lands between Spain and Portugal according to their location on one side or the other of an imaginary geographical line 50 degrees west of Greenwich that extends in a ___ direction.
A. north and south B. crosswise C. easterly D. south east E. north and west 4. One of Magellan's ships explored the ___ of South America for a passage across the continent. A. coastline B. mountain range C. physical features D. islands E. none of the above 5. Four of the ships sought a passage along a southern ___. A. coast B. inland C. body of land with water on three sides D. border E. answer not available 6. The passage was found near 50 degrees S of ___. A. Greenwich B. The equator C. Spain D. Portugal E. Madrid 7. In the spring of 1521, the ships crossed the ___ now called the International Date Line. A. imaginary circle passing through the poles B. Imaginary line parallel to the equator C. area D. land mass E. answer not found in article Marie Curie was one of the most accomplished scientists in history. Together with her husband, Pierre, she discovered radium, an element widely used for treating cancer, and studied uranium and other radioactive substances. Pierre and Marie's amicable collaboration later helped to unlock the secrets of the atom. Marie was born in 1867 in Warsaw, Poland, where her father was a professor of physics. At the early age, she displayed a brilliant mind and a blithe personality. Her great exuberance for learning prompted her to continue with her studies after high school. She became disgruntled, however, when she learned that the university in Warsaw was closed to women. Determined to receive a higher education, she defiantly left Poland and in 1891 entered the Sorbonne, a French university, where she earned her master's degree and doctorate in physics. Marie was fortunate to have studied at the Sorbonne with some of the greatest scientists of her day, one of whom was Pierre Curie. Marie and Pierre were married in 1895 and spent many productive years working together in the physics laboratory. A short time after they discovered radium, Pierre was killed by a horse-
drawn wagon in 1906. Marie was stunned by this horrible misfortune and endured heartbreaking anguish. Despondently she recalled their close relationship and the joy that they had shared in scientific research. The fact that she had two young daughters to raise by herself greatly increased her distress. Curie's feeling of desolation finally began to fade when she was asked to succeed her husband as a physics professor at the Sorbonne. She was the first woman to be given a professorship at the world-famous university. In 1911 she received the Nobel Prize in chemistry for isolating radium. Although Marie Curie eventually suffered a fatal illness from her long exposure to radium, she never became disillusioned about her work. Regardless of the consequences, she had dedicated herself to science and to revealing the mysteries of the physical world. 8. The Curies' ____ collaboration helped to unlock the secrets of the atom. A. friendly B. competitive C. courteous D. industrious E. chemistry 9. Marie had a bright mind and a __personality. A. strong B. lighthearted C. humorous D. strange E. envious 10. When she learned that she could not attend the university in Warsaw, she felt___. A. hopeless B. annoyed C. depressed D. worried E. none of the above 11. Marie ___ by leaving Poland and traveling to France to enter the Sorbonne. A. challenged authority B. showed intelligence C. behaved D. was distressed E. answer not available in article 12. _____she remembered their joy together. A. Dejectedly B. Worried C. Tearfully D. Happily E. Sorrowfully 13. Her ____ began to fade when she returned to the Sorbonne to succeed her husband. A. misfortune B. anger C. wretchedness
D. disappointment E. ambition 14. Even though she became fatally ill from working with radium, Marie Curie was never ____. A. troubled B. worried C. disappointed D. sorrowful E. disturbed Mount Vesuvius, a volcano located between the ancient Italian cities of Pompeii and Herculaneum, has received much attention because of its frequent and destructive eruptions. The most famous of these eruptions occurred in A. D. 79. The volcano had been inactive for centuries. There was little warning of the coming eruption, although one account unearthed by archaeologists says that a hard rain and a strong wind had disturbed the celestial calm during the preceding night. Early the next morning, the volcano poured a huge river of molten rock down upon Herculaneum, completely burying the city and filling in the harbor with coagulated lava. Meanwhile, on the other side of the mountain, cinders, stone and ash rained down on Pompeii. Sparks from the burning ash ignited the combustible rooftops quickly. Large portions of the city were destroyed in the conflagration. Fire, however, was not the only cause of destruction. Poisonous sulphuric gases saturated the air. These heavy gases were not buoyant in the atmosphere and therefore sank toward the earth and suffocated people. Over the years, excavations of Pompeii and Herculaneum have revealed a great deal about the behavior of the volcano. By analyzing data, much as a zoologist dissects a specimen animal, scientist have concluded that the eruption changed large portions of the area's geography. For instance, it turned the Sarno River from its course and raised the level of the beach along the Bay of Naples. Meteorologists studying these events have also concluded that Vesuvius caused a huge tidal wave that affected the world's climate. In addition to making these investigations, archaeologists have been able to study the skeletons of victims by using distilled water to wash away the volcanic ash. By strengthening the brittle bones with acrylic paint, scientists have been able to examine the skeletons and draw conclusions about the diet and habits of the residents. Finally, the excavations at both Pompeii and Herculaneum have yielded many examples of classical art, such as jewelry made of bronze, which is an alloy of copper and tin. The eruption of Mount Vesuvius and its tragic consequences have provided us with a wealth of data about the effects that volcanoes can have on the surrounding area. Today volcanologists can locate and predict eruptions, saving lives and preventing the destruction of cities and cultures. 15. Herculaneum and its harbor were buried under ___lava.

Scientist have used ___water to wash away volcanic ash from the skeletons of victims. A. bottled B. volcanic C. purified D. sea E. fountain Conflict had existed between Spain and England since the 1570s. England wanted a share of the wealth that Spain had been taking from the lands it had claimed in the Americas. Elizabeth I, Queen of England, encouraged her staunch admiral of the navy, Sir Francis Drake, to raid Spanish ships and towns. Though these raids were on a small scale, Drake achieved dramatic success, adding gold and silver to England's treasury and diminishing Spain's omnipotence. Religious differences also caused conflict between the two countries. Whereas Spain was Roman Catholic, most of England had become Protestant. King Philip II of Spain wanted to claim the throne and make England a Catholic country again. To satisfy his ambition and also to retaliate against England's theft of his gold and silver, King Philip began to build his fleet of warships, the Armada, in January 1586. Philip intended his fleet to be indestructible. In addition to building new warships, he marshaled one hundred and thirty sailing vessels of all types and recruited more than nineteen thousand robust soldiers and eight thousand sailors. Although some of his ships lacked guns and others lacked ammunition, Philip was convinced that his Armada could withstand any battle with England.
The martial Armada set sail from Lisbon, Portugal, on May 9,1588, but bad weather forced it back to port. The voyage resumed on July 22 after the weather became more stable. The Spanish fleet met the smaller, faster, and more maneuverable English ships in battle off the coast of Plymouth, England, first on July 31 and again on August 2. The two battles left Spain vulnerable, having lost several ships and with its ammunition depleted. On August 7, while the Armada lay at anchor on the French side of the Strait of Dover, England sent eight burning ships into the midst of the Spanish fleet to set it on fire. Blocked on one side, the Spanish ships could only drift away, their crews in panic and disorder. Before the Armada could regroup, the English attacked again on August 8. Although the Spaniards made a valiant effort to fight back, the fleet suffered extensive damage. During the eight hours of battle, the Armada drifted perilously close to the rocky coastline. At the moment when it seemed that the Spanish ships would be driven onto the English shore, the wind shifted, and the Armada drifted out into the North Sea. The Spaniards recognized the superiority of the English fleet and returned home, defeated. 20. Sir Francis Drake added wealth to the treasury and diminished Spain's ____.

The victory of the small Greek democracy of Athens over the mighty Persian empire in 490 B. C. is one of the most famous events in history. Darius, king of the Persian empire, was furious because Athens had interceded for the other Greek city-states in revolt against Persian domination. In anger the king sent an enormous army to defeat Athens. He thought it would take drastic steps to pacify the rebellious part of the empire. Persia was ruled by one man. In Athens, however, all citizens helped to rule. Ennobled by this participation, Athenians were prepared to die for their city-state. Perhaps this was the secret of the remarkable victory at Marathon, which freed them from Persian rule. On their way to Marathon, the Persians tried to fool some Greek city-states by claiming to have come in peace. The frightened citizens of Delos refused to believe this. Not wanting to abet the conquest of Greece, they fled from their city and did not return until the Persians had left. They were wise, for the Persians next conquered the city of Etria and captured its people. Tiny Athens stood alone against Persia. The Athenian people went to their sanctuaries. There they prayed for deliverance. They asked their gods to expedite their victory. The Athenians refurbished their weapons and moved to the plain of Marathon, where their little band would meet the Persians. At the last moment, soldiers from Plataea reinforced the Athenian troops. The Athenian army attacked, and Greek citizens fought bravely. The power of the mighty Persians was offset by the love that the Athenians had for their city. Athenians defeated the Persians in archery and hand combat. Greek soldiers seized Persian ships and burned them, and the Persians fled in terror. Herodotus, a famous historian, reports that 6400 Persians died, compared with only 192 Athenians. 25. Athens had ____the other Greek city-states against the Persians. A. refused help to B. intervened on behalf of C. wanted to fight D. given orders for all to fight E. defeated 26. Darius took drastic steps to ___ the rebellious Athenians.

The Trojan War is one of the most famous wars in history. It is well known for the ten-year duration, for the heroism of a number of legendary characters, and for the Trojan horse. What may not be familiar, however, is the story of how the war began. According to Greek myth, the strife between the Trojans and the Greeks started at the wedding of Peleus, King of Thessaly, and Thetis, a sea nymph. All of the gods and goddesses had been invited to the wedding celebration in Troy except Eris, goddesses of discord. She had been omitted from the guest list because her presence always embroiled mortals and immortals alike in conflict. To take revenge on those who had slighted her, Eris decided to cause a skirmish. Into the middle of the banquet hall, she threw a golden apple marked “for the most beautiful.” All of the goddesses began to haggle over who should possess it. The gods and goddesses reached a stalemate when the choice was narrowed to Hera, Athena, and Aphrodite. Someone was needed to settle the controversy by picking a winner. The job eventually fell to Paris, son of King Priam of Troy, who was said to be a good judge of beauty. Paris did not have an easy job. Each goddess, eager to win the golden apple, tried aggressively to bribe him. “I'll grant you vast kingdoms to rule, “ promised Hera. “Vast kingdoms are nothing in comparison with my gift,” contradicted Athena. “Choose me and I'll see that you win victory and fame in war.” Aphrodite outdid her adversaries, however. She won the golden apple by offering Helen, Zeus' daughter and the most beautiful mortal, to Paris. Paris, anxious to claim Helen, set off for Sparta in Greece. Although Paris learned that Helen was married, he accepted the hospitality of her husband, King Menelasu of Sparta, anyway. Therefore, Menelaus was outraged for a number of reasons when Paris departed, taking Helen and much of the king's wealth back to Troy. Menelaus collected his loyal forces and set sail for Troy to begin the war to reclaim Helen. 30. Eris was known for ___both mortals and immortals. A. scheming against B. involving in conflict C. feeling hostile toward D. ignoring E. comforting 31. Each goddess tried ___to bribe Paris.
A. boldly B. effectively C. secretly D. carefully E. answer not stated 32. Athena ___ Hera, promising Paris victory and fame in war. A. denied the statement of B. defeated C. agreed with D. restated the statement E. questioned the statement
One of the most intriguing stories of the Russian Revolution concerns the identity of Anastasia, the youngest daughter of Czar Nicholas II. During his reign over Russia, the Czar had planned to revoke many of the harsh laws established by previous czars. Some workers and peasants, however, clamored for more rapid social reform. In 1918 a group of these people, known as Bolsheviks, overthrew the government. On July 17 or 18, they murdered the Czar and what was thought to be his entire family. Although witnesses vouched that all the members of the Czar's family had been executed, there were rumors suggesting that Anastasia had survived. Over the years, a number of women claimed to be Grand Duchess Anastasia. Perhaps the best –known claimant was Anastasia Tschaikovsky, who was also known as Anna Anderson. In 1920, eighteen months after the Czar's execution, this terrified young woman was rescued from drowning in a Berlin river. She spent two years in a hospital, where she attempted to reclaim her health and shattered mind. The doctors and nurses thought that she resembled Anastasia and questioned heer about her background. She disclaimed any connection with the Czar's family. Eight years later, though, she claimed that she was Anastasia. She said that she had been rescued by two Russian soldiers after the Czar and the rest of her family had been killed. Two brothers named Tschaikovsky had carried her into Romania. She had married one of the brothers, who had taken her to Berlin and left her there, penniless and without a vocation. Unable to invoke the aid of her mother's family in Germany, she had tried to drown herself. During the next few years, scores of the Czar's relatives, ex-servants, and acquaintances interviewed her. Many of these people said that her looks and mannerisms were evocative of the Anastasia that they had known. Her grandmother and other relatives denied that she was the real Anastasia, however. Tried of being accused of fraud, Anastasia immigrated to the United States in 1928 and took the name Anna Anderson. She still wished to prove that she was Anastasia, though, and returned to Germany in 1933 to bring suit against her mother's family. There she declaimed to the court, asserting that she was indeed Anastasia and deserved her inheritance. In 1957, the court decided that it could neither confirm nor deny Anastasia's identity. Although we will probably never know whether this woman was the Grand
Duchess Anastasia, her search to establish her identity has been the subject of numerous books, plays, and movies. 33. Some Russian peasants and workers___for social reform.

King Louis XVI and Queen Marie Antoinette ruled France from 1774 to 1789, a time when the country was fighting bankruptcy. The royal couple did not let France's insecure financial situation limit their immoderate spending, however. Even though the minister of finance repeatedly warned the king and queen against wasting money, they continued to spend great fortunes on their personal pleasure. This lavish spending greatly enraged the people of France. They felt that the royal couple bought its luxurious lifestyle at the poor people's expense. Marie Antoinette, the beautiful but exceedingly impractical queen, seemed uncaring about her subjects; misery. While French citizens begged for lower taxes, the queen embellished her palace with extravagant works of art. She also surrounded herself with artists, writers, and musicians, who encouraged the queen to spend money even more profusely.
While the queen's favorites glutted themselves on huge feasts at the royal table, many people in France were starving. The French government taxed the citizens outrageously. These high taxes paid for the entertainments the queen and her court so enjoyed. When the minister of finance tried to stop these royal spendthrifts, the queen replaced him. The intense hatred that the people felt for Louis XVI and Marie Antoinette kept building until it led to the French Revolution. During this time of struggle and violence (1789-1799), thousands of aristocrats, as well as the king and queen themselves, lost their lives at the guillotine. Perhaps if Louis XVI and Marie Antoinette had reined in their extravagant spending, the events that rocked France would not have occurred. 38. The people surrounding the queen encouraged her to spend money ____. A. wisely B. abundantly C. carefully D. foolishly E. joyfully 39. The minister of finance tried to curb these royal ___. A. aristocrats B. money wasters C. enemies D. individuals E. spenders
Many great inventions are greeted with ridicule and disbelief. The invention of the airplane was no exception. Although many people who heard about the first powered flight on December 17,1903, were excited and impressed, others reacted with peals of laughter. The idea of flying an aircraft was repulsive to some people. Such people called Wilbur and Orville Wright, the inventors of the first flying machine, impulsive fools. Negative reactions, however, did not stop the Wrights. Impelled by their desire to succeed, they continued their experiments in aviation. Orville and Wilbur Wright had always had a compelling interest in aeronautics and mechanics. As young boys they earned money by making and selling kites and mechanical toys. Later, they designed a newspaper-folding machine, built a printing press, and operated a bicycle-repair shop. In 1896, when they read about the death of Otto Lilienthal, the brother's interest in flight grew into a compulsion. Lilienthal, a pioneer in hang-gliding, had controlled his gliders by shifting his body in the desired direction. This idea was repellent to the Wright brothers, however, and they searched for more efficient methods to control the balance of airborne vehicles. In 1900 and 1901, the Wrights tested numerous gliders and developed control techniques. The brothers' inability to obtain enough lift power for the gliders almost led them to abandon their efforts. After further study, the Wright brothers concluded that the published tables of air pressure on curved surfaces must be wrong. They set up a wind tunnel and began a series of experiments with model wings. Because of their efforts, the old tables were repealed in time and replaced by the first reliable figures for air pressure on curved surfaces. This work, in turn, made it possible for them to design a machine that
would fly. In 1903 the Wrights built their first airplane, which cost less than one thousand dollars. They even designed and built their own source of propulsion- a lightweight gasoline engine. When they started the engine on December 17, the airplane pulsated wildly before taking off. The plane managed to stay aloft for twelve seconds, however, and it flew one hundred twenty feet. By 1905 the Wrights had perfected the first airplane that could turn, circle, and remain airborne for half an hour at a time. Others had flown in balloons or in hang gliders, but the Wright brothers were the first to build a full-size machine that could fly under its own power. As the contributors of one of the most outstanding engineering achievements in history, the Wright brothers are accurately called the fathers of aviation. 40. The idea of flying an aircraft was ___to some people. A. boring B. distasteful C. exciting D. needless E. answer not available 41. People thought that the Wright brothers had ____. A. acted without thinking B. been negatively influenced C. been too cautious D. had not given enough thought E. acted in a negative way 42. The Wright's interest in flight grew into a ____. A. financial empire B. plan C. need to act D. foolish thought E. answer not in article 43. Lilenthal's idea about controlling airborne vehicles was ___the Wrights. A. proven wrong by B. opposite to the ideas of C. disliked by D. accepted by E. opposed by 44. The old tables were __ and replaced by the first reliable figures for air pressure on curved surfaces. A. destroyed B. canceled C. multiplied D. discarded E. not used 45. The Wrights designed and built their own source of ____. A. force for moving forward B. force for turning around C. turning D. force to going backward E. none of the above
Exercise 2: Americans have always been interested in their Presidents' wives. Many First Ladies have been remembered because of the ways they have influenced their husbands. Other First Ladies have made the history books on their own. At least two First Ladies, Bess Truman and Lady Bird Johnson, made it their business to send signals during their husbands' speeches. When Lady Bird Johnson thought her husband was talking too long, she wrote a note and sent it up to the platform. It read, “It's time to stop!” And he did. Once Bess Truman didn't like what her husband was saying on television, so she phoned him and said,” If you can't talk more politely than that in public, you come right home.” Abigail Fillmore and Eliza Johnson actually taught their husbands, Millard Fillmore and Andrew Johnson, the thirteenth and seventeenth Presidents. A schoolteacher, Abigail eventually married her pupil, Millard. When Eliza Johnson married Andrew, he could not read or write, so she taught him herself. It was First Lady Helen Taft's idea to plant the famous cherry trees in Washington, D. C. Each spring these blossoming trees attract thousands of visitors to the nation's capital. Mrs. Taft also influenced the male members of her family and the White House staff in a strange way: she convinced them to shave off their beards! Shortly after President Wilson suffered a stroke, Edith Wilson unofficially took over most of the duties of the Presidency until the end of her husband's term. Earlier, during World War I, Mrs. Wilson had had sheep brought onto the White House lawn to eat the grass. The sheep not only kept the lawn mowed but provided wool for an auction sponsored by the First Lady. Almost $100,000 was raised for the Red Cross. Dolly Madison saw to it that a magnificent painting of George Washington was not destroyed during the War of 1812. As the British marched toward Washington, D. C., she remained behind to rescue the painting, even after the guards had left. The painting is the only object from the original White House that was not burned. One of the most famous First Ladies was Eleanor Roosevelt, the wife of President Franklin D. Roosevelt. She was active in political and social causes throughout her husband's tenure in office. After his death, she became famous for her humanitarian work in the United Nations. She made life better for thousands of needy people around the world. 1. What is the main idea of this passage?
A. The Humanitarian work of the First Ladies is critical in American government. B. Dolly Madison was the most influential president's wife. C. Eleanor Roosevelt transformed the First Lady image. D. The First Ladies are important in American culture. E. The First Ladies are key supporters of the Presidents.
Of the many kinds of vegetables grown all over the world, which remains the favorite of young and old alike? Why, the potato, of course. Perhaps you know them as “taters,” “spuds,” or “Kennebees,” or as “chips,” “Idahoes,” or even “shoestrings.” No matter, a potato by any other name is still a potato- the world's most widely grown vegetable. As a matter of fact, if you are an average potato eater, you will put away at least a hundred pounds of them each year. That's only a tiny portion of the amount grown every year, however. Worldwide, the annual potato harvest is over six billion bags- each bag containing a hundred pounds of spuds, some of them as large as four pounds each. Here in the United States, farmers fill about four hundred million bags a year. That may seem like a lot of “taters,” but it leaves us a distant third among world potato growers. Polish farmers dig up just over 800 million bags a year, while the Russians lead the world with nearly 1.5 billion bags. The first potatoes were grown by the Incas of South America, more than four hundred years ago. Their descendants in Ecuador and Chile continue to grow the vegetable as high as fourteen thousand feet up in the Andes Mountains. ( That's higher than any other food will grow.) Early Spanish and English explorers shipped potatoes to Europe, and they found their way to North America in the early 1600s. People eat potatoes in many ways-baked, mashed, and roasted, to name just three. However, in the United States most potatoes are devoured in the form of French fries. One fast-food chain alone sells more than $1 billion worth of fries each year. No wonder, then, that the company pays particular attention to the way its fries are prepared. Before any fry makes it to the people who eat at these popular restaurants, it must pass many separate tests. Fail any one and the spud is rejected. To start with, only russet Burbank potatoes are used. These Idaho potatoes have less water content than other kinds, which can have as much as eighty percent water. Once cut into “shoestrings” shapes, the potatoes are partly fried in a secret blend of oils, sprayed with liquid sugar to brown them, steam dried at high heat, then flash frozen for shipment to individual restaurants.
Before shipping, though, every shoestring is measured. Forty percent of a batch must be between two and three inches long. Another forty percent has to be over three inches. What about the twenty percent that are left in the batch? Well, a few short fries in a bag are okay, it seems. So, now that you realize the enormous size and value of the potato crop, you can understand why most people agree that this part of the food industry is no “small potatoes.” 2. What is the main idea of this passage? A. Potatoes from Ireland started the Potato Revolution. B. The average American eats 50 lbs of potatoes a year. C. French fries are made from potatoes. D. Potatoes are a key vegetable in America. E. The various terms for potatoes have a long history.
What does the word patent mean to you? Does it strike you as being something rather remote from your interests? If it does, stop and think a moment about some of the commonplace things that you use every day, objects that you take for granted as part of the world around you. The telephone, radio, television, the automobile, and the thousand and one other things (even the humble safety pin) that enrich our lives today once existed only as ideas in the minds of men. If it had not been possible to patent their ideas and thus protect them against copying by others, these inventions might never have been fully developed to serve mankind. If there were no patent protection there would be little incentive to invent and innovate, for once the details of an invention became known, hordes of imitators who did not share the inventor's risks and expenses might well flood the market with their copies of his product and reap much of the benefit of his efforts. The technological progress that has made America great would wither rapidly under conditions such as these. The fundamental principles in the U. S. patent structure came from England. During the glorious reign of Queen Elizabeth I in England, the expanding technology was furthered by the granting of exclusive manufacturing and selling privileges to citizens who had invented new processes or tools- a step that did much to encourage creativity. Later, when critics argued that giving monopoly rights to one person infringed on the rights of others, an important principle was added to the patent structure: The Lord Chief Justice of England stated that society had everything to gain and nothing to lose by granting exclusive privileges to an inventor, because a patent for an invention was granted for something new that society never had before.
Another basic principle was brought into law because certain influential people in England had managed to obtain monopoly control over such age-old products as salt, and had begun charging as much as the traffic would bear. The public outcry became so great that the government was forced to decree that monopoly rights could be awarded only to those who created or introduced something really unique. These principles are the mainstays of our modern patent system in the United States. In colonial times patent law was left up to the separate states. The inconsistency, confusion, and unfairness that resulted clearly indicated the need for a uniform patent law, and the men who drew up the Constitution incorporated one. George Washington signed the first patent law on April 10,1790, and less than four months later the first patent was issued to a man named Samuel Hopkins for a chemical process, an improved method of making potash for use in soapmaking. In 1936 the Patent Office was established as a separate bureau. From the staff of eight that it maintained during its first year of operation it has grown into an organization of over 2500 people handling more than 1600 patent applications and granting over 1000 every week. The Patent Office in Washington, D. C., is the world's largest library of scientific and technical data, and this treasure trove of information is open for public inspection. In addition to more than 3 million U. S. patents, it houses more than 7 million foreign patents and thousands of volumes of technical literature. Abraham Lincoln patented a device to lift steam vessels over river shoals, Mark Twain developed a self-pasting scrapbook, and millionaire Cornelius Vanderbilt invented a shoe-shine kit. A patent may be granted for any new and useful process, machine, article of manufacture, or composition of matter ( a chemical compound or combinations of chemical compounds), or any distinct and new variety; of plant, including certain mutants and hybrids. The patent system has also helped to boost the wages of the American worker to an unprecedented level; he can produce more and earn more with the computer, adding machines, drill press or lathe. Patented inventions also help keep prices down by increasing manufacturing efficiency and by stimulating the competition that is the foundation of our free enterprise system. The decades of history have disclosed little need for modification of the patent structure. Our patent laws, like the Constitution from which they grew, have stood the test of time well. They encouraged the creative processes, brought untold benefits to society as a whole, and enabled American technology to outstrip that of the rest of the civilized world. 3. What is the main idea of this passage?
A. The patent system encourages free enterprise. B. The Constitution protects the patent system. C. The patent system in England has been influential in American patent development. D. Patents are important tools for inventors. E. Patented inventions protect the inventor, free enterprise, and the creative process.
Most people think it's fine to be “busy as a beaver.” Little do they know. Beavers may work hard, but often they don't get much done. Beavers are supposed to be great tree cutters. It is true that a beaver can gnaw through a tree very quickly. (A six-inch birch takes about ten minutes.) But then what? Often the beaver does not make use of the tree. One expert says that beavers waste one out of every five trees they cut. For one thing, they do not choose their trees wisely. One bunch of beavers cut down a cottonwood tree more than one hundred feet tall. Then they found that they could not move it. In thick woods a tree sometimes won't fall down. It gets stuck in the other trees. Of course, doesn't think to cut down the trees that are in the way. So a good tree goes to waste. Some people think that beavers can make a tree fall the way they want it to. Not true. (In fact, a beaver sometimes gets pinned under a falling tree.) When beavers cut a tree near a stream, it usually falls into the water. But they do not plan it that way. The fact is that most trees lean toward the water to start with. Now what about dam building? Most beaver dams are wonders of engineering. The best ones are strongly built of trees, stones, and mud. They are wide at the bottom and narrow at the top. Beavers think nothing of building a dam more than two hundred feet long. One dam, in Montana, was more than two thousand feet long. The largest one ever seen was in New Hampshire. It stretched four thousand feet. It made a lake large enough to hold forty beaver homes. So beavers do build good dams. But they don't always build them in the right places. They just don't plan. They will build a dam across the widest part of the stream. They don't try to find a place where the stream is narrow. So a lot of their hard work is wasted.
Beavers should learn that it's not enough to be busy. You have to know what you're doing, too. For example, there was one Oregon beaver that really was a worker. It decided to fix a leak in a man-made dam. After five days of work it gave up. The leak it was trying to block was the lock that boats go through. 4. What is the main idea of this passage? A. Beavers may be hard working animals, but they don't always choose the most efficient mechanisms. B. Beavers are excellent dam builders. C. New Hampshire was the site of the largest beaver dam. D. Beavers are well developed tree cutters. E. Beavers are poor surveyors of aquatic environments in some cases.
The raisin business in America was born by accident. It happened in 1873 in the San Joaquin Valley of California. Many farmers raised grapes in this valley. That year, just before the grape harvest, there was a heat wave. It was one of the worst heat waves ever known. It was so hot the grapes dried on the vines. When they were picked, California had its first raisin crop. People were surprised to find how good raisins were. Everybody wanted more. So the San Joaquin farmers went into the raisin business. Today, of course, they do not let the grapes dry on the vines. They treat them with much more care. In late August the grapes start to ripen. They are tested often for sweetness. The growers wait until the sugar content is twenty-one percent. Then they know the grapes are ripe enough to be picked. Skilled workers come to the vineyards. They pick the bunches of grapes by hand. The workers fill their flat pans with grapes. They gently empty the pans onto squares of paper. These squares lie between the long rows of vines. They sit in the sun. Here the grapes stay while the sun does its work. It may take two weeks or longer. The grapes are first dried on one side. When they have reached the right color, they are turned to dry on the other side. The grapes are dried until only fifteen percent of the moisture is left. Then they have turned into raisins. The raisins are rolled up in the paper on which they have dried. Trucks take them from the fields. They are poured into big boxes called sweatboxes. Each box holds one hundred and sixty pounds of raisins. Here, any raisins that are a bit too dry
take moisture from those that have a bit too much. After a while they are all just moist enough. The big boxes are trucked next to the packaging plant. They are emptied onto a conveyor belt that shakes the raisins gently. This knocks them from their stems. A blast of air whisks the stems away. The water bath is next. Then the plump brown raisins have a last inspection. They are again checked for moisture and sugar. Then they go on a belt to packing machines. Here they are poured into packages, which are automatically weighed and sealed. The raisins are now ready for market. 5. What is the main idea of this passage? A. The creation of raisins in America was an accident. B. The process of raisin development requires multiple steps. C. Raisins on the grocery store shelf undergo a brief fermentation process. D. Raisins are cleaned thoroughly at the packing plant. E. California has been the leader in American raisin development.
In 1976, Sichan Siv was crawling through the jungle, trying to escape from Cambodia. By 1989, however, Siv was working in the White House, in Washington D. C., as an advisor to the President of the United States. How did this strange journey come about? Like millions of Cambodians, Siv was a victim of a bloody civil war. One of the sides in this war was the Cambodian government. The other was a group called the Khmer Rouge. When the Khmer Rouge won the war, the situation in Cambodia got worse. Many people were killed, while others were forced into hard labor. Sometimes entire families were wiped out. Siv came from a large family that lived in the capital of Cambodia. After finishing high school, Siv worked for a while with a Cambodian airline company. Later, he taught English. After that, he took a job with CARE, an American group that was helping victims of the war. Siv had hope to leave Cambodia before the Khmer Rouge took over the country. Unfortunately, he was delayed. As a result, he and his family were taken from their homes and forced to labor in rice fields. After a while, Siv managed to escape. He rode an old bicycle for miles, trying to reach Thailand where he would be free and safe. For three weeks he slept on the ground and tried to hide from the soldiers who were looking for him. Caught at last, he was afraid he would be killed. Instead, he was put into a labor camp, where he worked eighteen hours each day without rest. After several months, he escaped again; this time he made it. The journey, however,
was a terrifying one. After three days of staggering on foot through mile after mile of thick bamboo, Siv finally made his way to Thailand. Because he had worked for an American charity group, Siv quickly found work in a refugee camp. Soon he was on his way to the states. He arrived in June of 1976 and got a job-first picking apples and then cooking in a fast-food restaurant. Siv, however, wanted more than this; he wanted to work with people who, like himself, had suffered the hardship of leaving their own countries behind. Siv decided that the best way to prepare for this kind of work was to go to college. He wrote letters to many colleges and universities. They were impressed with his school records from Cambodia, and they were impressed with his bravery. Finally, in 1980, he was able to study at Columbia University in New York City. After finishing his studies at Columbia, Siv took a job with the United Nations. He married an American woman and became a citizen. After several more years, he felt that he was very much a part of his new country. In 1988, Siv was offered a job in the White House working for President Reagan's closest advisors. It was a difficult job, and he often had to work long hours. However the long hard work was worth it, because Siv got the opportunity to help refugees in his work. 6. What is the main idea of this passage? A. Persistence and courage are global ideas. B. Siv covered a large area during his life. C. Siv persevered to become an American citizen D. Siv overcame numerous challenges to come to American and help others. E. Siv persevered to become an American citizen.
When you want to hang the American flag over the middle of a street, suspend it vertically with the blue field, called the union, to the north and east-west street. When the flag is displayed with another banner from crossed staffs, the American flag is on the right. Place the staff of the American flag in front of the other staff. Raise the flag quickly and lower it slowly and respectfully. When flying the flag at half-mast, hoist it to the top of the pole for a moment before lowering it to mid-pole. When flying the American flag with banners from states or cities, raise the nation's banner first and lower it last. Never allow the flag to touch the ground. 7. What is the main idea of this passage? A. The American flag is the symbol of American freedom. B. The American flag has fifty stars. C. Placing the American flag inappropriately will draw government intervention.
D. American flag should be flown differently in certain situations. ","The flag should be lowered quickly and respectfully.
What if someone told you about a kind of grass that grows as tall as the tallest trees? A grass that can be made as strong as steel? A grass from which houses, furniture, boats, and hundreds of other useful things can be made? A grass that you would even enjoy eating? Would you believe that person? You should, for that grass is bamboo, the “wood” of 1,001 uses. Bamboo may look like wood, but it is part of the family of plants that includes wheat, oats, and barley. It is a kind of grass. This grass is not just a material for making useful products. Young bamboo is eaten, often mixed with other vegetables, in many Asian foods. Bamboo grows in many parts of the world. In the United States it grows in an area from Virginia west to Indiana and south to Florida, Louisiana, and Texas. Most bamboo, however, is found in warm, wet climates, especially in Asia and on the islands of the South Pacific Ocean. In most Asian countries, bamboo is nearly as important as rice. Many Asians live in bamboo houses. They sit on bamboo chairs and sleep on bamboo mats. They fence their land with bamboo and use the wood for cages for chickens and pigs. Bamboo is used to build large buildings as well as homes. When it is glued in layers, it becomes as strong as steel. On some islands in the South Pacific, bamboo is even used for water pipes. This extraordinary material has many other uses. It is used to make musical instruments, such as flutes and recorders. Paper made from bamboo has been highly prized by artists for thousands of years. Bamboo is light and strong, and it bends without breaking. It is cheap, floats on water, almost never wears out, and is easy to grow. Nothing else on earth grows quite so fast as bamboo. At times you can even see it grow! Botanists have recorded growths of more than three feet in just twenty-four hours! Bamboo is hollow and has a strong root system that almost never stops growing and spreading. In fact, only after it flowers, an event that may happen only once every thirty years, will bamboo die. There are more than a thousand kinds of bamboo. The smallest is only three inches tall and one-tenth of an inch across. The largest reaches more than two hundred feet in height and seven inches in diameter. No wonder, then, that the lives of nearly half the people on earth would change enormously if there were no longer any bamboo. No wonder, too, that to many people bamboo is a symbol of happiness and good fortune.
8. What is the main idea of this passage? A. Bamboo has at least 2,000 uses. B. Bamboo grows at an amazing rate and is found primarily in Asia. C. Bamboo is an amazing grass that can be used in multiple ways. D. There are at least a 1,000 types of bamboo. E. Bamboo could be considered a flower in some cases.
Every year since 1986, some of the world's most daring runners have gathered in the desert of Morocco. They are there to take part in one of the most difficult races in the world. The Marathon of the Sands, as it is called, covers over 125 miles of desert and mountain wilderness. The runners complete the course in fewer than seven days, and they run with their food, clothing, and sleeping bags on their backs. The Marathon of the Sands was founded in 1986 by Patrick Bauer. His idea was to give the runners, who come from all over the world, a special kind of adventure. Most of the runners in this race have found that they form deep friendships with the other runners during their days and nights in the desert. Facing terrible heat and complete exhaustion, they learn much about themselves and each other. For most of the runners, though, the challenge of the race is the main reason for coming. On the first day, for example, they run fifteen miles across a desert of sand, rocks, and thorny bushes. Few runners finish the day without blistered and raw feet. They also suffer from a lack of water. (They are allowed less than nine quarts of water during each day of the race.) Most of all, they are exhausted when they arrive at the campsite for the night. The second day, the runners are up at 6:00 A. M. Within a few hours, it is 100 degrees F, but the runners do not hesitate. They must cover eighteen miles that day. That night, they rest. They must be ready for the next day's run. On the third day, the runners must climb giant sand dunes- the first they have faced. Dust and sand mix with the runners' sweat. Soon their faces are caked with mud. After fifteen miles of these conditions, the runners finally reach their next camp. The race continues like this for four more days. The fourth and fifth days are the worst. On the fourth day, the runners pass through a level stretch and a beautiful, tree-filled oasis, but then, on this and on the next day, they cross more than twentyone miles of rocks and sand dunes. The temperature soars to 125 degrees F, and many runners cannot make it. Helicopters rush fallen runners to medical help. Runners who make it to the end of the fifth day know that the worst is over.
On the sixth day, heat and rocks punish the racers terribly. In the Valley of Dra, the wind picks up and, as the desert heat is thrust against them with great force, they grow more and more exhausted. The seventh day is the last, with only twelve miles to be covered. The dusty, tired, blistered runners set out at daybreak. Near the finish line, children race along with the runners, for everybody has caught the excitement. The ones who have run the whole marathon know they have accomplished what most people could not even dream of. “During the hard moments,” says one contestant who has raced here twice, “I'd think, „Why am I here?' Then I'd realize I was there to find my limits.” 9. What is the main idea of this passage? A. The Marathon of the Sands race tests the limits of human endurance. B. The runners run at their own pace. C. The race causes the strong to stumble and the weak to not finish. D. The seventh day is the hardest day of the race. E. Every runner runs the race to find their human limits.
High in the Andes Mountains in Peru stands the ancient city of Machu Picchu. No one knows why this great city was built, nor is it likely that we will ever know. Nevertheless, the deserted city of Machu Picchu is important for what it reveals about the ancient Inca people of South America. The Incas once ruled a great empire that covered a large part of the South American continent. The empire was more than five hundred years old when the first Spanish explorers, looking for gold, went to that continent in the sixteenth century. The Incas were an advanced people. They were skillful engineers who paved their roads and built sturdy bridges. They plowed the land in such a way that rains would not wash away valuable soil. They dug ditches to carry water into dry areas for farming. Even though they did not know about the wheel, the Incas were able to move huge stone blocks- some as heavy as ten tons- up the sides of mountains to build walls. The blocks were fitted so tightly, without cement of any kind, that it would be impossible to slip a knife blade between them! The walls have stood firm through great storms and earthquakes that have destroyed many modern buildings. The Incas were great artists, too. Today, Incan dishes and other kinds of pottery are prized for their wonderful designs. Since both gold and silver were in great supply, the Incas created splendid objects from these precious metals.
While it is true that the Incas had no written language, they kept their accounts by using a system of knotted strings of various lengths and colors. The sizes of the knots and the distances between them represented numbers. At its height, the Incan empire included as many as thirty million people. The emperor ruled them with an iron hand. He told his subjects where to live, what to plant, how long they should work-even whom they could marry. Since he owned everything, the emperor gave what he wished when he wished- and in the amount he wished -to his people. In 1533 Spanish explorers led by Francisco Pizarro murdered the emperor of the Incas. Earlier, the heir to the Incan empire had also been killed. The Incas, who had always been entirely dependent on their emperor, now had no recognized leader. The Spaniards easily conquered the empire and plundered its riches. Have the Incas disappeared from South America? Not at all. In Peru alone, once the center of that great empire, eighty percent of the twenty million people are descendants of the Inca people. Evidence of the Incan empire can be found in many other places in South America as well. You can even visit Machu Picchu. The remains of this ancient city still stand high in the mountains of Peru, an awesome tribute to this once powerful empire. 10. What is the main idea of this passage? A. The Incas once inhabited the ancient city of Machu Picchu. B. Peru was the primary country of the Incas. C. The Incan empire can be found in ancient cities and was plundered by the Spanish. D. Spanish conquerors destroyed the Incan empire in the thirteenth century. E. Machu Picchu was the capital of the Incan empire.
Exercise 3: In 1892 the Sierra Club was formed. In 1908 an area of coastal redwood trees north of San Francisco was established as Muir Woods National Monument. In the Sierra Nevada mountains, a walking trail from Yosemite Valley to Mount Whitney was dedicated in 1938. It is called John Muir Trail. John Muir was born in 1838 in Scotland. His family name means “moor,” which is a meadow full of flowers and animals. John loved nature from the time he was small. He also liked to climb rocky cliffs and walls. When John was eleven, his family moved to the United States and settled in Wisconsin. John was good with tools and soon became an inventor. He first
invented a model of a sawmill. Later he invented an alarm clock that would cause the sleeping person to be tipped out of bed when the timer sounded. Muir left home at an early age. He took a thousand-mile walk south to the Gulf of Mexico in 1867and 1868. Then he sailed for San Francisco. The city was too noisy and crowded for Muir, so he headed inland for the Sierra Nevadas. When Muir discovered the Yosemite Valley in the Sierra Nevadas, it was as if he had come home. He loved the mountains, the wildlife, and the trees. He climbed the mountains and even climbed trees during thunderstorms in order to get closer to the wind. He put forth the theory in the late 1860's that the Yosemite Valley had been formed through the action of glaciers. People ridiculed him. Not until 1930 was Muir's theory proven correct. Muir began to write articles about the Yosemite Valley to tell readers about its beauty. His writing also warned people that Yosemite was in danger from timber mining and sheep ranching interests. In 1901 Theodore Roosevelt became president of the United States. He was interested in conservation. Muir took the president through Yosemite, and Roosevelt helped get legislation passed to create Yosemite National Park in 1906. Although Muir won many conservation battles, he lost a major one. He fought to save the Hetch Valley, which people wanted to dam in order to provide water for San Francisco. In the late 1913 a bill was signed to dam the valley. Muir died in 1914. Some people say losing the fight to protect the valley killed Muir. 1. What happened first? A. The Muir family moved to the United States. B. Muir Woods was created. C.

When using a metal file, always remember to bear down on the forward stroke only. On the return stroke, lift the file clear of the surface to avoid dulling the instrument's teeth. Only when working on very soft metals is it advisable to drag the file's teeth slightly on the return stroke. This helps clear out metal pieces from between the teeth. It is best to bear down just hard enough to keep the file cutting at all times. Too little pressure uses only the tips of the teeth; too much pressure can chip the teeth. Move the file in straight lines across the surface. Use a vice to grip the work so that your hands are free to hold the file. Protect your hands by equipping the file with a handle. Buy a wooden handle and install it by inserting the pointed end of the file into the handle hole. 6.

“Old woman,” grumbled the burly white man who had just heard Sojourner Truth speak, “do you think your talk about slavery does any good? I don't care any more for your talk than I do for the bite of a flea.” The tall, imposing black woman turned her piercing eyes on him. “Perhaps not,” she answered, “but I'll keep you scratching.” The little incident of the 1840s sums up all that Sojourner Truth was: utterly dedicated to spreading her message, afraid of no one, forceful and witty in speech. Yet forty years earlier, who could have suspected that a spindly slave girl growing up in a damp cellar in upstate New York would become one of the most remarkable women in American history? Her name then was Isabella (many slaves had no last names), and by the time she was fourteen she had seen both parents die of cold and hunger. She herself had been sold several times. By 1827, when New York freed its slaves, she had married and borne five children. The first hint of Isabella's fighting spirit came soon afterwards, when her youngest son was illegally seized and sold. She marched to the courthouse and badgered officials until her son was returned to her. In 1843, inspired by religion, she changed her name to Sojourner(meaning “one who stays briefly”) Truth, and, with only pennies in her purse, set out to preach against slavery. From New England to Minnesota she trekked, gaining a reputation for her plain but powerful and moving words. Incredibly, despite being black and female (only white males were expected to be public speakers), she drew thousands to town halls, tents, and churches to hear her powerful, deep-voiced pleas on equality for blacks-and for women. Often she had to face threatening hoodlums. Once she stood before armed bullies and sang a hymn to them. Awed by her courage and her commanding presence, they sheepishly retreated. During the Civil War she cared for homeless ex-slaves in Washington. President Lincoln invited her to the White House to bestow praise on her. Later, she petitioned
Congress to help former slaves get land in the West. Even in her old age, she forced the city of Washington to integrate its trolley cars so that black and white could ride together. Shortly before her death at eighty-six, she was asked what kept her going. “I think of the great things,” replied Sojourner. 10.

The Galapagos Islands are in the Pacific Ocean, off the western coast of South America. They are a rocky, lonely spot, but they are also one of the most unusual places in the world. One reason is that they are the home of some of the last giant tortoises left on earth. Weighing hundreds of pounds, these tortoises, or land turtles, wander slowly around the rocks and sand of the islands. Strangely, each of these islands has its
own particular kinds of tortoises. There are seven different kinds of tortoises on the eight islands, each kind being slightly different from the other. Hundreds of years ago, thousands of tortoises wandered around these islands. However, all that changed when people started landing there. When people first arrived in 1535, their ships had no refrigerators. This meant that fresh food was always a problem for the sailors on board. The giant tortoises provided a solution to this problem. Ships would anchor off the islands, and crews would row ashore and seize as many tortoises as they could. Once the animals were aboard the ship, the sailors would roll the tortoises onto their backs. The tortoises were completely helpless once on their backs, so they could only lie there until used for soups and stews. Almost 100,000 tortoises were carried off in this way. The tortoises faced other problems, too. Soon after the first ships, settlers arrived bringing pigs, goats, donkeys, dogs and cats. All of these animals ruined life for the tortoises. Donkey and goats ate all the plants that the tortoises usually fed on, while the pigs. Dogs and cats consumed thousands of baby tortoises each year. Within a few years, it was hard to find any tortoise eggs-or even any baby tortoises. By the early 1900s, people began to worry that the last of the tortoises would soon die out. No one, however, seemed to care enough to do anything about the problem. More and more tortoises disappeared, even though sailors no longer needed them for food. For another fifty years, this situation continued. Finally, in the 1950s, scientist decided that something must be done. The first part of their plan was to get rid of as many cats, dogs and other animals as they could. Next, they tried to make sure that more baby tortoises would be born. To do this, they started looking for wild tortoise eggs. They gathered the eggs and put them in safe containers. When the eggs hatched, the scientists raised the tortoises in special pens. Both the eggs and tortoises were numbered so that the scientists knew exactly which kinds of tortoises they had-and which island they came from. Once the tortoises were old enough and big enough to take care of themselves, the scientists took them back to their islands and set them loose. This slow, hard work continues today, and, thanks to it, the number of tortoises is now increasing every year. Perhaps these wonderful animals will not disappear after all. 20. What happened first?

Charles A. Lindbergh is remembered as the first person to make a nonstop solo flight across the Atlantic, in 1927. This feat, when Lindbergh was only twenty-five years old, assured him a lifetime of fame and public attention. Charles Augustus Lindbergh was more interested in flying airplanes than he was in studying. He dropped out of the University of Wisconsin after two years to earn a living performing daredevil airplane stunts at country fairs. Two years later, he joined the United States Army so that he could go to the Army Air Service flighttraining school. After completing his training, he was hired to fly mail between St. Louis and Chicago. Then came the historic flight across the Atlantic. In 1919, a New York City hotel owner offered a prize of $25,000 to the first pilot to fly nonstop from New York to Paris. Nine St. Louis business leaders helped pay for the plane Lindbergh designed especially for the flight. Lindbergh tested the plane by flying it from San Diego to New York, with an overnight stop in St. Louis. The flight took only 20 hours and 21 minutes, a transcontinental record. Nine days later, on May 20,1927, Lindbergh took off from Long Island, New York, at 7:52 A. M. He landed at Paris on May 21 at 10:21 P. M. He had flown more than 3,600 miles in less than thirty four hours. His flight made news around the world. He was given awards and parades everywhere he went. He was presented with the U. S. Congressional Medal of Honor and the first Distinguished Flying Cross. For a long time, Lindbergh toured the world as a U. S. goodwill ambassador. He met his
future wife, Anne Morrow, in Mexico, where her father was the United States ambassador. During the 1930s, Charles and Anne Lindbergh worked for various airline companies, charting new commercial air routes. In 1931, for a major airline, they charted a new route from the east coast of the United States to the Orient. The shortest, most efficient route was a great curve across Canada, over Alaska, and down to China and Japan. Most pilots familiar with the Arctic did not believe that such a route was possible. The Lindberghs took on the task of proving that it was. They arranged for fuel and supplies to be set out along the route. On July 29, they took off from Long Island in a specially equipped small seaplane. They flew by day and each night landed on a lake or a river and camped. Near Nome, Alaska, they had their first serious emergency. Out of daylight and nearly out of fuel, they were forced down in a small ocean inlet. In the next morning's light, they discovered they had landed on barely three feet of water. On September 19, after two more emergency landings and numerous close calls, they landed in China with the maps for a safe airline passenger route. Even while actively engaged as a pioneering flier, Lindbergh was also working as an engineer. In 1935, he and Dr. Alexis Carrel were given a patent for an artificial heart. During World War I in the 1940s, Lindbergh served as a civilian technical advisor in aviation. Although he was a civilian, he flew over fifty combat missions in the Pacific. In the 1950s, Lindbergh helped design the famous 747 jet airliner. In the late 1960s, he spoke widely on conservation issues. He died August 1974, having lived through aviation history from the time of the first powered flight to the first steps on the moon and having influenced a big part of that history himself. 29. What did Lindbergh do before he crossed the Atlantic? A. He charted a route to China. B. He graduated from flight-training school. C. He married Anne Morrow. D. He acted as a technical advisor during World War II. E. He was responsible for the fuel supply for planes. 30. What happened immediately after Lindbergh crossed the Atlantic? A. He flew the mail between St. Louis and Chicago. B. He left college. C. He attended the Army flight-training school. D. He was given the Congressional Medal of Honor. E. He married Anne Morrow. 31.

Lindbergh patented an artificial heart. B. The Lindberghs mapped a route to the Orient. C. Lindbergh helped design the 747 airline. D. Lindbergh flew fifty combat missions. E. Charles finally was given an honorary degree from college.
Always read the meter dials from the right to the left. This procedure is much easier, especially if any of the dial hands are near the zero mark. If the meter has two dials, and one is smaller than the other, it is not imperative to read the smaller dial since it only registers a small amount. Read the dial at the right first. As the dial turns clockwise, always record the figure the pointer has just passed. Read the next dial to the left and record the figure it has just passed. Continue recording the figures on the dials from right to left. When finished, mark off the number of units recorded. Dials on water and gas meters usually indicate the amount each dial records. 34. These instructions show you how to – A. read a meter B. turn the dials of a meter C. install a gas meter D. repair a water meter E. be prepared for outside employment 35. Always read the meter dialsA. from top to bottom B. from right to left C. from left to right D. from the small to the large dial E. from the large dial to the small dial 36. As you read the first dial, record the figures
A. on the smaller dial B. the pointer is approaching C. the pointer has just passed D. at the top E. at the bottom 37. When you have finished reading the meter, mark offA. the number of units recorded B. the figures on the small dial C. the total figures D. all the zero marks E. the last reading of the month
The village of Vestmannaeyjar, in the far northern country of Iceland, is as bright and clean and up-to-date as any American or Canadian suburb. It is located on the island of Heimaey, just off the mainland. One January night in 1973, however, householders were shocked from their sleep. In some backyards red-hot liquid was spurting from the ground. Flaming “skyrockets” shot up and over the houses. The island's volcano, Helgafell, silent for seven thousand years, was violently erupting! Luckily, the island's fishing fleet was in port, and within twenty-four hours almost everyone was ferried to the mainland. But then the agony of the island began in earnest. As in a nightmare, fountains of burning lava spurted three hundred feet high. Black, baseball-size cinders rained down. An evil-smelling, eye-burning, throat-searing cloud of smoke and gas erupted into the air, and a river of lava flowed down the mountain. The constant shriek of escaping steam was punctuated by ear-splitting explosions. As time went on, the once pleasant village of Vestmannaeyjar took on a weird aspect. Its street lamps still burning against the long Arctic night, the town lay under a thick blanket of cinders. All that could be seen above the ten-foot black drifts were the tips of street signs. Some houses had collapsed under the weight of cinders; others had burst into flames as the heat ignited their oil storage tanks. Lighting the whole lurid scene, fire continued to shoot from the mouth of the looming volcano. The eruption continued for six months. Scientists and reporters arrived from around the world to observe the awesome natural event. But the town did not die that easily. In July, when the eruption ceased, the people of Heimaey Island returned to assess the chances of rebuilding their homes and lives. They found tons of ash covering the ground. The Icelanders are a tough people, however, accustomed to the strange and violent nature of their Arctic land. They dug out their homes. They even used the cinders to build new roads and airport runways. Now the new homes of Heimaey are warmed from water pipes heated by molten lava.

Time and Distance Speed: We have the relation between speed, time and distance as follows: Speed = distance / time. So the distance covered in unit time is called speed. This forms the basis for Time and Distance. It can be re-written as Distance = Speed X Time or Time = Distance / Speed.
Units of Speed: The units of speed are kmph (km per hour) or m / s. 1 kmph = 5 / 18 m / s 1 m / s = 18 / 5 kmph
Average Speed: When the travel comprises of various speeds then the concept of average speed is to be applied. Average Speed = Total distance covered / Total time of travel
Note: In the total time above, the time of rest is not considered. Example 1:
If a car travels along four sides of a square at 100 kmph, 200 kmph, 300 kmph and 400 kmph find its average speed.
Soln: Average Speed = Total distance / Total time. Let each side of square be x km. Then the total distance = 4x km. The total time is sum of individual times taken to cover each side. To cover x km at 100 kmph, time = x / 100. For the second side time = x / 200. Using this we can write average speed = 4x / (x/100 + x/200 + x/300 + x/400) = 192 kmph.
Example 2: A man if travels at 5/6 th of his actual speed takes 10 min more to travel a distance. Find his usual time.
Soln: Let s be the actual speed and t be the actual time of the man. Now the speed is (5/6)s and time is (t+10) min. But the distance remains the same. So distance 1 = distance 2 => s X t = (5/6)s X (t+10) => t = 50 min.
Example 3: If a person walks at 30 kmph he is 10 min late to his office. If he travels at 40 kmph then he reaches to his office 5 min early. Find the distance to his office.
Soln: Let the distance to his office be d. The difference between the two timings is given as 15 min = 1 / 4 hr. Now if d km are covered at 30 kmph then time = d/30. Similarly second time = d/40. So, d/30 – d/40 = 1 / 4 => d = 30 km.
Note: When two objects move with speeds s1 and s2 a. b.
In opposite directions their combined speed = s1 + s2 In same direction their combined speed = s1 ~ s2.
Example 4: Two people start moving from the same point at the same time at 30 kmph and 40 kmph in opposite directions. Find the distance between them after 3 hrs.
Soln:
Speed = 30 + 40 = 70 kmph (since in opposite directions) Time = 3 hrs So distance = speed X time = 70 X 3 = 210 km.
Example 5: A starts from X to Y at 6 am at 40 kmph and at the same time B starts from Y to X at 50 kmph. When will they meet if X and Y are 360 km apart?
Soln: Distance = 360 km Speed = 40 + 50 = 90 kmph. Time = distance / speed = 360 / 90 = 4hrs from 6 am => 10 am. Example 6: A starts from X to Y at 6 am at a speed of 50 kmph. After two hours B starts from Y to X at 60 kmph. When will they meet if X and Y are 430 km apart?
Soln: By the time B started A traveled for 2 hrs => 2 X 50 = 100 km. So at 8 am, distance = 430 – 100 = 330 km Speed = 50 + 60 = 110 kmph. Time = distance / speed = 330 / 110 = 3 hrs from 8 am => 11 am.
Note: When a train crosses a negligible length object (man / pole / tree) the distance that it has to travel is its own length. When a train has to cross a lengthy object (train / bridge / platform) the distance it has to travel is the sum of its length and the length of the object.
Example 7: If a train traveling at 40 kmph crosses another train of length 100m traveling at 14 kmph in opposite direction in 30 s find the length of the train.
Soln: Let length of train be d. Distance to be covered = d + 100. Speed = 40 + 14 = 54 kmph = 54 X 5 / 18 = 15 m / s Time = 30 s. Distance = speed X time => d+100 = 15 X 30 => d = 350 m.
Note: If a man rows a boat along the stream flowing at speed S2 then it is termed downstream speed and is given by S down = S1 + S2 , where S1 is speed of boat in still water.
If a man rows a boat opposite to the stream flowing at S2 then it is termed upstream and is given by S up = S1 – S2.

How far is the place? 1) 16 km 2) 10 km 3) 12 km 4) 8 km
Time and Work If a person can complete a work in ‘n’ days then he can do 1/n part of the work in one day. The amount of work done be a person in 1 day is called his efficiency.
Example: A can do a work in 10 days. Then the efficiency of A is given by A = 1 / 10.
Note: Number of days required to do a work = work to be done / work per day.
Example 1: If A can do a work in 10 days, B can do it in 20 days and C in 30 days in how many days will the three together do it?
Soln: The efficiencies are A = 1/10, B = 1/20 and C = 1/30 So work done per day by the three = 1/10 + 1/20 + 1/30 = 11/60 => No of days = 60/11 = 5.45 days.
Example 2: If A and B can do a work in 10 days , B and C can do it in 20 days and C and A can do it in 40 days in what time all the three can do it? Soln: A+B = 1/10 B+C = 1/20 C+A = 1/40 Adding all the three we get 2(A+B+C) = 7/40 => A+B+C = 7/80 => No of days = 80/7 days.
Note: If all the people do not work for all the time then the principle below can be used: mA + nB + oC = 1.
(1 is the total work)
Here, m=no of days A worked n=no of days B worked o=no of days C worked A,B,C = efficiencies
Example 3: If A can do a work in 12 days, B can do it in 18 days and C in 24 days. All the three started the work. A left after two days and C left three days before the completion of the work. How many days are required to complete the work?
Soln: Let the total no of days be x. A worked only for 2 days, B worked for x days and C worked for x-3 days. So, mA + nB + oC = 1 2(1/12) + x(1/18) + (x-3)(1/24) = 1 12 + 4x + 3(x-3) = 72 x = 69 / 7 days.
Note: The ratio of dividing wages = ratio of efficiencies = ratio of parts of work done
Example 4: A can do a work in 10 days and B can do it in 30 days and C in 60 days. If the total wages for the work is Rs. 1800 what is the share of A?
Soln: Ratio of wages = 1/10 : 1/30 : 1/60 = 6 : 2 : 1 (Multiplying each term by LCM 60) So total 9 equal parts in Rs. 1800 => each part = Rs. 200 => share of A = 6 parts = Rs. 1200.
Note: When pipes are used filling the tank they are treated similar to the men working but some outlet pipes emptying the tank are present whose work will be considered negative.
Example 5: A pipe can fill a tank in 5 hrs but because of a leak a the bottom it takes 1 hr extra. In what time can the leak alone empty the tank?
Soln: Let the filling pipe be A. A = 1 / 5. But with the leak L, A – L = 1 / 6 ( A-L because leak is outlet) So, 1/L = 1 / 5 – 1/ 6 = 1/30 => Leak can empty the tank in 30 hrs.
Example 6: A pipe A can fill the tank in 10 hrs, B can fill it in 20 hrs and C can empty in 40 hrs. All are opened at the same time. After how many hours shall the pipe B be closed such that the tank can be filled in 10 hrs?
Soln: Let the pipe B be closed after x hrs. Then A worked for 10 hrs, B worked for x hrs and C worked for 10 hrs. mA + nB – oC = 1
(since C is outlet)
10(1/10) + x(1/20) – 10(1/40) = 1 x = 5 hrs.
