Answer:
10 days and 16 hours.
Step-by-step explanation:
15 men work in 16 days to complete the work. So 1 man contributes 16/15 days.
For 20 men there is an addition of 5 men. [20–15)* 16/15] days = 16/3 days. Substract 16/3 days from 16 days = 16 - (16/3) = 10 days and 16 hours.

Let 20 men will take x days to complete the work.
Since, there is a relation of inverse proportion between no of men and no of days.
