A piece of work can be done by 6 men and 5 women in 6 day it can be done by 18 men and 15 women in - एक काम को 6 आदमी और 5 औरत 6 दिन में में पूरा करते है। उसी काम को 18 आदमी और 15 औरतें कितने दिन में पूरा करेगी?

6 men + 5 women complete work in 6 days. This means (6M + 5W) × 6 = 1 unit of work. We have 18 men + 15 women, which is exactly 3 times the original team (since 18M + 15W = 3 × (6M + 5W)). If 3 times the workforce works, the time taken is 1/3 of original time = 6/3 = 2 days. Option A (2) is correct. This is an inverse proportion problem.
