Solution:
Given:
Number of men = 28
Time taken to complete the work = 65 days
To find:
Number of men required to complete the work in 35 days
We can solve this problem using the concept of "man-days". The number of man-days required to complete a piece of work is equal to the total number of men multiplied by the number of days taken.
Let's calculate the total man-days required to complete the work in 65 days:
Total man-days = Number of men × Number of days
Total man-days = 28 men × 65 days
Total man-days = 1820
Now, let's calculate the number of men required to complete the work in 35 days:
Number of men = Total man-days ÷ Number of days
Number of men = 1820 ÷ 35
Number of men ≈ 52
Therefore, the correct answer is option B) 52 men.
Explanation:
- We are given that 28 men can complete the work in 65 days.
- To find the number of men required to complete the work in 35 days, we use the concept of man-days.
- The total man-days required to complete the work can be calculated by multiplying the number of men by the number of days.
- Substituting the given values, we find that the total man-days required is 1820.
- To find the number of men required in 35 days, we divide the total man-days by the number of days.
- After performing the calculation, we find that approximately 52 men are required to complete the work in 35 days.
- Thus, option B) 52 men is the correct answer.

Total man-days = 28 men × 65 days
Total man-days = 1820
Now, let's calculate the number of men required to complete the work in 35 days:
Number of men = Total man-days ÷ Number of days
Number of men = 1820 ÷ 35
Number of men ≈ 52
Therefore, the correct answer is option B) 52 men.
