Question

if 15 men can repair a road in 24 days then how long will it take 9 men to repair the same road​

Answer 1

Answer:

40 Days

Explanation:

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.
