80 men can construct a small footpath in 60 days.
We need to find how many more men should be employed if the job is to be finished in 20 days.
Formula Used:
Work = Men × Days
Calculation:
Work done by 80 men in 60 days:
Work = 80 × 60
Work = 4800 man-days
Let x be the number of men required to complete the work in 20 days:
Work = x × 20
Since the work done is the same, we have:
4800 = x × 20
⇒ x = 4800 / 20
⇒ x = 240
The current number of men is 80, so the number of additional men required:
Additional men = 240 - 80
Additional men = 160
The correct answer is option 3.
