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.
