Answer 2

Hi friends, here is your answer :-

The easiest way to determine solution for such problems is knowing the proportions. 15 men take 24 days, assume 30 men it will take 12 days and assume 7 or 8 men it will be 48 days. The pattern involves inverse proportions, lesser men more days and vice versa. Coming back we need to find 9 men time period which suggests

15*24/9 = 40 days is actual solution.
