## Accenture MCQ Aptitude Questions And Answers

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 x*45 = (x-10)*60. So we get x = 40

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

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

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

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%

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

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

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

9. **A Boat takes total 16 hours for traveling downstream from point A to point B and coming back point C which is somewhere between A and B. If the speed of the Boat in Still water is 9 Km/hr and the rate of stream is 6 Km/hr, then what is the distance between A and C?**

17. **Eight years ago, Pranathi’s age was equal to the sum of the present ages of her one son and one daughter. Five years hence, the respective ratio between the ages of her daughter and her son that time will be 7:6. If Pranathi’s husband is 7 years elder to her and his present age is three times the present age of their son, what is the present age of the daughter?**

A. 19 years

B. 27 years

C. 15 years

D. 23 years

**Answer –** D. 23 years

**Explanation:**

P – 8 = S + D —(1)

6D + 30 = 7S + 35 —(2)

H = 7 + P

H = 3S

3S = 7 + P —-(3)

Solving equation (1),(2) and (3) D = 23

Therefore, the present age of the daughter is 23 years

18.** Shas married 8 year ago. Today her age is 9/7 times to that time of marriage. At present his son’s age is 1/6th of her age. What was her son’s age 3 year ago?**

A. 4 yr

B. 2 yr

C. 3 yr

D. 5 yr

**Answer – **B. 2 yr

**Explanation:**

Let us assume that Sravan’s age 8 year ago = x

Present age = x + 8

x + 8 = 9/7 x

7(x + 8)= 9x

x = 28; 28 + 8 = 36

Son’s age = 1/6 * 36 = 6

Son’s age 4 year ago = 6-4 =2

19. **The respective ratio between the present age of Mani and Dheeraj is x : 42. Mani is 8 years younger than Murali. Murali’s age after 8 years will be 33 years. The difference between Dheeraj’s and Mani’s age is same as the present age of Murali. What is the value of x?**

A. 18

B. 10

C. 16

D. 17

**Answer –** D. 17

**Explanation:**

Murali’s age after 8 years = 33 years

Murali’s present age = 33 – 8= 25 years

Mani’s present age = 25 – 8 = 17 years

Dheeraj’s present age = 17 + 25 = 42 years

Ratio between Mani and Dheeraj = 17: 42

X = 17

20. **Revanth’s present age is three times his son’s present age and 4/5th of his father’s present age. The average of the present ages of all of them is 62 years. What is the difference between the Revanth’s son’s present age and Revanth’s father’s present age?**
