6 men or 10 women can reap a field in 15 days, then the number of days that 12 men and 5 women will take to reap the same field is :

5
6
8
12

Correct Answer: 6

Explanation:

Work done by 6 men = work done by 10 women.
Work done by 1 man = work done by 10 / 6 = 5/3 women
∴ 12 men + 5 women = 12 x ( 5 / 3) + 5 = 25 women
∴ W₁ x D ₁ = W₂ x D₂ W = women, D=days
10 X 15 = 25 x D₂
D₂ = 6
