Step-by-step explanation:

10 men *15 days = 150 man-days. So 1 man does (1/150)th of the work in a day.

15 women *12 days = 180 woman-days. So 1 woman does (1/180)th of the work in a day.

So 10 men and 15 women do (10/150)+(15/180) = (60/900)+(75/900) = 135/900 or (15/100)th part of the work in 1 day

So 10 men and 15 women will complete the work in 100/15 = 6.67 days.
