1. 39 persons can repair a road in 12 days, working 5 hours a day. In how many days will 30 persons, working 6 hours a day, complete the work?

A. 10

B. 13

C. 14

D. 15

Explanation:

Let's calculate how much time it takes to repair the road if just 1 person were working on it.

5 hours a day for 12 days makes it 60 hours per person.

39 people working 60 hours each makes it 39 × 60 = 2340 hours in total.

Now we have 30 people working 6 hours a day.

That means 30 × 6 = 180 hours are spent each day.

We need a total of 2340 hours. With 180 hours every day, that's going to take 2340/ 180=13 days.

2. Anil does a work in 90 days, Bittu in 40 days and Chintu in 12 days. They work one after another for a day each, starting with Anil followed by Bittu and then by Chintu. If the total wages received are Rs 360 and Anil, Bittu, Chintu share them in the ratio of the work done, find their respective individual wages.

A. Rs 40, Rs 60 and Rs 260

B. Rs 36, Rs 81 and Rs 243

C. Rs 42, Rs 86 and Rs 232

D. Rs 38, Rs 88 and Rs 234

Explanation:

Assume there are 360 units of work (LCM of 40, 60 and 12).

Hence, A, B and C can do 4,9 and 30 units per day or together 43 units every 3 days.

So in 24 days, 43 x 8 = 344 units of work is completed. In the next 2 days, 13 units are completed and on 27th day, C takes 110th of a day to finish the rest.

So, A and B worked for 9 days each and have hence put in 36 and 81 units respectively, and the rest of the 243 units is put in by C.

The wages shall also be distributed in the same ratio as: Rs 36, Rs 81 and Rs 243.

3. A alone can do a piece of work in 6 days and B alone in 8 days. A and B undertook to do it for Rs. 3200. With the help of C, they completed the work in 3 days. How much is to be paid to C?

A. Rs 375

B. Rs 400

C. Rs 600

D. Rs 800

Explanation:

C's 1 day's work = (1/3) - (1/6) + (1/8) = (1/3) - (7/24) = 1/24.

A's wages: B's wages: C's wages = (1/6): (1/8): (1/24) = 4: 3: 1.

C's share (for 3 days) = Rs. 3 x (1/24) x 3200 = Rs. 400.

4. In a flight of 600 km, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced by 200 km/hr. and the time of flight increased by 30 minutes. The duration of the flight is:

A. 1 hours

B. 2 hours

C. 3 hours

D. 4 hours

Explanation:

Let the duration of the flight be x hours.

Then, 600/x - 600/ (x + 1/2) = 200.

=> 600/x - 1200/ (2x + 1) = 200.

=> x (2x + 1) = 3.

=> 2x2 + x - 3 = 0.

=> (2x + 3) (x - 1) = 0.

=> x = 1 hr. [neglecting the -ve value of x]

5. 2 hours after train A leaves Lucknow a train B leaves the same station traveling in the same direction at an average speed of 20 km/hr. After traveling 6 hrs. the train B overtakes the train A. What is the average speed of the train A?

A. 15 km/hr.

B. 16 km/hr.

C. 17 km/hr.

D. 18 km/hr.

Explanation:

Total distance covered by B=20*6=120km.

Total time taken by A to cover same distance=2+6=8 hrs.

Hence, The average speed of A=120/8=15 km/hr.

6. In a four numbers set, the second number is twice the first number, the first is one-third of the third and the third is 5 times the fourth. The average of the numbers is 24.75. The largest of these numbers is:

A. 9

B. 25

C. 30

D. None of these

Explanation:

Let the fourth number be x.

Then, third number = 5x, first number = 5x/3.

And second number = 10x/3

=> x + 5x + 10x/3 + 5x/3 = (33 x 4) or 11x = 132 or x = 12.

So, the numbers are 20, 40, 60 and 12.

Hence, the largest number = 60.

7. In an examination, a girl's average marks were 57 per paper. If she had obtained 10 more marks for her Maths paper and 5 more marks for her English paper, her average per paper would have been 60. How many papers were there in the examination?

A. 3

B. 9

C. 10

D. 5

Explanation:

Let the number of papers be x.

Then, 57x + 10 + 5 = 60x.

=> 60x - 57x = 15.

=> 3x = 15.

=> x = 5.

8. A shopkeeper sells one transistor for Rs. 840 at a gain of 20% and another for Rs. 960 at a loss of 4%. His total gain or loss percent is:

A. (100/17) % Loss

B. (100/17) % Gain

C. (20/3) % Loss

D. None of these

Explanation:

Let the cost price of 1st transistor be Rs. x and the cost price of 2nd transistor be Rs. y.

S.P. of 1st transistor at 20% profit = Rs. 840.

=> (x + 20% of x) = 840.

=> x*(120/100) = 840.

=> x = 700.

S.P. of 2nd transistor at 4% loss = Rs. 960.

=> (y - 4% of y) = 960.

=> y*(96/100) = 960.

=> y = 1000.

So, total C.P. = (x + y) = Rs. 1700.

Total S.P. = 840 + 960 = 1800.

Profit = (S.P. - C.P.) = (1800 - 1700) = Rs. 100.

% profit = (100/17) %.

9. 100 oranges are bought at the rate of Rs. 350 and sold at the rate of Rs. 48 per dozen. The percentage of profit or loss is:

A. 100/7% gain

B. 15% gain

C. 100/7% loss

D. 15% loss

Explanation:

C.P. of 100 oranges = Rs. 350

=> C.P. of 1 orange = Rs. 3.5

S.P. of 12 oranges = Rs. 48

=> S.P. of 1 orange = Rs. 4

Profit per orange = Rs. 0.5.

%profit = (0.5/3.5) * 100 = 100/7 %.

10. The percentage profit earned by selling an article for Rs. 1920 is equal to the percentage loss incurred by selling the same article for Rs. 1280. At what price should the article be sold to make 25% profit?

A. Rs 2000

B. Rs 2023

C. Rs 2200

D. Data Inadequate

Explanation:

Let the C.P. of the article be Rs. x

Given that % profit earned by selling article at Rs. 1920 = % loss incurred by selling article at Rs. 1280.

=> [ (1920-x) / x] * 100 = [(x-1280)/ x] * 100.

=> 1920−x = x - 1280.

=> 2x = 3200.

=> x = 1600.

S.P. for 25% profit = Rs. 1600 + 25% of Rs. 1600 = Rs. 1600*(125/100) = Rs. 2000.

11. Puzzle: -

Santa distributes 2 gifts to every child in the street at the Christmas evening. He mistakenly gives 4 gifts to some children. If he distributed 50 gifts to 21 children. How many children got 4 gifts?

A. 40

B. 50

C. 30

D. 25

Explanation:

Santa had 50 gifts and there were 21 children, and each of them had to receive at least 2 gifts, so Santa should have given 42 gifts in total, but instead he gave 4 gifts to some of them.

It means, he gave 8 more gifts in pairs of 2 i.e. he had 4 pairs of gifts. That means, 4 children got 4 gifts.

Verification:

17 children got only 2 gifts i.e. 17 * 2 = 34 gifts.

4 children got 4 gifts each, so: 4 * 4 = 16 gifts.

Total is 50.

30. PARAGRAPH COMPLETION: -

What happens to our brains as we age is of crucial importance not just to science but to public policy? By 2030, for example, 72 million people in the US will be over 65, double the figure in 2000 and their average life expectancy will likely have edged above 20 years. However, this demographic time-bomb would be much less threatening if the elderly were looked upon as intelligent contributors to society rather than as dependents in long-term decline.

A. The idea that we get dumber as we grow older is just a myth, according to brain research that will encourage anyone old enough to know better.

B. It is time we rethink what we mean by the ageing mind before our false assumptions result in decisions and policies that marginalize the old or waste precious public resources to re-mediate problems that do not exist.

C. Many of the assumptions scientists currently make about ‘cognitive decline’ are seriously flawed and, for the most part, formally invalid.

D. Using computer models to simulate young and old brains, Ramscar and his colleagues found they could account for the decline in test scores simply by factoring in experience

Explanation:

This paragraph discusses the growing aging populace and need to identify how they can be contributors to the society. Choice (b) continues the line of thought about not wasting public resources based on existing assumptions about cognitive decline with age.

Choice (d) is also eliminated right away as it talks of a “decline in test scores”, the test not detailed here.

Choice (a) is incorrect as it doesn’t talk of the aged in the society, just lays down the basic premise that they are not on the path of mental decline. This would have been discussed before the paragraph we are trying to complete begins.

Choice (c) builds on the idea discussed by choice (a) and doesn’t fit as well as (b) to complete the paragraph.
