A Correct answer
Explanation

This is an inverse proportion problem. 20 men * 16 days = 10 men * x days. 320 = 10x. x = 32.

AI explanation

Using the formula M1 times D1 equals M2 times D2, we have 20 men times 16 days equal to 10 men times the unknown days. This gives 320 equal to 10 times the required days. Dividing 320 by 10 results in 32 days.
