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.

Answer:

12

Step-by-step explanation:

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.

Therefore,

20x = 16 \times 15 \\  \\ x =  \frac{240}{20}  \\  \\ x = 12
