Question 1

Question

Answer

Explanation

Question

1. A certain number of men take 45 days to complete work. If there are 10 men less

then they will take 60 days to complete the work. Find the original number of men.

A. 50

B. 60

C. 30

D. 40

Answer

D. 40

Explanation

Let us assume initially there are X men. Then x45 = (x-10)60. So we get x = 40

Question 2

Question

Answer

Explanation

Question

2. 5 men and 10 boys can do a piece of work in 30 days and 8 men and 12 boys can do

the work in 20 days then the ratio of daily work done by a man to that of a boy.

A. 5:1

B. 4:5

C. 6:1

D. 7:3

Answer

C. 6:1

Explanation

Given that, 5m + 10b = 1/30 and 8m + 12b = 1/20

after solving we get m = 1/200 and b = 1/1200

so required ratio = (1/200) : (1/1200) = 6:1

Question 3

Question

Answer

Explanation

Question

3. 4 women and 5 men working together can do 3 times the work done by 2 women

and one man together. Calculate the work of a man to that of a woman.

A. 1:1

B. 3:2

C. 1:2

D. 2:1

Answer

A. 1:1

Explanation

Given

4w + 5m = 3*(2w + m)

i.e. 2w = 2m

so the ratio of work done by man to woman is 1:1

Question 4

Question

Answer

Explanation

Question

4. Manoj can do a work in 20 days, while Chandu can do the same work in 25 days.

They started the work jointly. A few days later Suresh also joined them and thus all of

them completed the whole work in 10 days. All of them were paid total Rs.1000. What

is the share of Suresh?

A. 100

B. 300

C. 200

D. 400

Answer

A. 100

Explanation

Efficiency of Manoj = 5%

The efficiency of Chandu = 4%

They will complete only 90% of the work = [(5+4)*10] =90

Remaining work was done by Suresh = 10%.

Share of Suresh = 10/100 * 1000 = 100

Question 5

Question

Answer

Explanation

Question

5. Nagarjuna lends Rs 30,000 of two of his friends. He gives Rs 15,000 to the first at

6% p.a. simple interest. He wants to make a profit of 10% on the whole. The simple

interest rate at which he should lend the remaining sum of money to the second friend

is

A. 8%

B. 12%

C. 14%

D. 16%

Answer

C. 14%

Explanation

Simple Interest on Rs 15000

=(15000×6×1)/100 = Rs. 900

Profit to made on Rs 30000

= 30000×10/100=Rs 3000

Simple Interest on Rs.15000 = 3000-900 = Rs.2100

Rate=(S.I.* 100)/(P * T)=(2100×100)/15000

=14% per annum

Therefore, the simple interest rate at which he should lend the remaining sum of money to

the second friend is 14%

Question 6

Question

Answer

Explanation

Question

6. A portion of $6600 is invested at a 5% annual return, while the remainder is invested

at a 3% annual return. If the annual income from the portion earning a 5% return is

twice that of the other portion, what is the total income from the two investments after

one year?

A. 270

B. 250

C. 280

D. 200

Answer

A. 270

Explanation

According to the given data

5x + 3y = z (total)

x + y = 6600

5x= 2(3y) [ condition given] 5x – 6y = 0

x + y = 6600

5x -6y = 0

Subtract both equations and you get x = 3600 so y = 3000

3600*.05 = 180

3000*.03 = 90

z (total) = 270

Therefore, the total income from the two investments after one year = 270

Question 7

Question

Answer

Explanation

Question

7. While calculating the weight of a group of men, the weight of 63 kg of one of the

member was mistakenly written as 83 kg. Due to this the average of the weights

increased by half kg. What is the number of men in the group?

A. 25

B. 20

C. 40

D. 60

Answer

C. 40

Explanation

Increase in marks lead to an increase in average by 1/2

So (83-63) = x/2

x = 40

Therefore, the number of men in the group are 40

Question 8

Question

Answer

Explanation

Question

8. In a group of 8 boys, 2 men aged at 21 and 23 were replaced, two new boys. Due to

this the average cost of the group increased by 2 years. What is the average age of

the 2 new boys?

A. 17

B. 30

C. 28

D. 23

Answer

B. 30

Explanation

According to the given data

Average of 8 boys increased by 2, this means the total age of boys increased by 8*2 = 16

yrs

So sum of ages of two new boys = 21+23+16 = 60

Average of these = 60/2 = 30

Question

Answer

Explanation

Question

Question 1

1. A certain number of men take 45 days to complete work. If there are 10 men less

then they will take 60 days to complete the work. Find the original number of men.

A. 50

B. 60

C. 30

D. 40

D. 40

Let us assume initially there are X men. Then x*45 = (x-10)*60. So we get x = 40

Question 2

2. 5 men and 10 boys can do a piece of work in 30 days and 8 men and 12 boys can do

the work in 20 days then the ratio of daily work done by a man to that of a boy.

A. 5:1

B. 4:5

C. 6:1

D. 7:3

C. 6:1

Given that, 5m + 10b = 1/30 and 8m + 12b = 1/20

after solving we get m = 1/200 and b = 1/1200

so required ratio = (1/200) : (1/1200) = 6:1

Question 3

3. 4 women and 5 men working together can do 3 times the work done by 2 women

and one man together. Calculate the work of a man to that of a woman.

A. 1:1

B. 3:2

C. 1:2

D. 2:1

A. 1:1

Given

4w + 5m = 3*(2w + m)

i.e. 2w = 2m

so the ratio of work done by man to woman is 1:1

Question 4

4. Manoj can do a work in 20 days, while Chandu can do the same work in 25 days.

They started the work jointly. A few days later Suresh also joined them and thus all of

them completed the whole work in 10 days. All of them were paid total Rs.1000. What

is the share of Suresh?

A. 100

B. 300

C. 200

D. 400

A. 100

Efficiency of Manoj = 5%

The efficiency of Chandu = 4%

They will complete only 90% of the work = [(5+4)*10] =90

Remaining work was done by Suresh = 10%.

Share of Suresh = 10/100 * 1000 = 100

Question 5

5. Nagarjuna lends Rs 30,000 of two of his friends. He gives Rs 15,000 to the first at

6% p.a. simple interest. He wants to make a profit of 10% on the whole. The simple

interest rate at which he should lend the remaining sum of money to the second friend

is

A. 8%

C. 14%

D. 16%

C. 14%

Simple Interest on Rs 15000

=(15000×6×1)/100 = Rs. 900

Profit to made on Rs 30000

= 30000×10/100=Rs 3000

Simple Interest on Rs.15000 = 3000-900 = Rs.2100

Rate=(S.I.* 100)/(P * T)=(2100×100)/15000

=14% per annum

Therefore, the simple interest rate at which he should lend the remaining sum of money to

the second friend is 14%

A. 270

According to the given data

5x + 3y = z (total)

x + y = 6600

5x= 2(3y) [ condition given] 5x – 6y = 0

Let us assume initially there are X men. Then x45 = (x-10)60. So we get x = 40

(S-R)42/5 = (S+R)7
