Question
10 boys can do a work in 9 days. How many boys are required to finish the same work in 6 days?
Ops:
- A. 18 boys
- B. 16 boys
- C. 15 boys
- D. 12 boys
Solution
This problem can be solved using the concept of man-days which is a unit of work done by one person in one day.
Step 1: Calculate the total man-days required to finish the work. If 10 boys can finish the work in 9 days, then the total man-days required is 10 boys * 9 days = 90 man-days.
Step 2: Calculate the number of boys required to finish the work in 6 days. If the total man-days required is 90 and we want to finish the work in 6 days, then the number of boys required is 90 man-days / 6 days = 15 boys.
So, the answer is C. 15 boys.
