Question 294861
10 men and 15 women can do a piece of work in 30 days, Calculate in how many days can the work be done by 12 men and 27 women working together?
--------------
No info is given on any difference between the rate of the men and women, so it must be assumed to be equal.

25*30 = 750 man-days total
750/39 =~ 19.23 days
