I did this question by plugging numbers


We know that W = 4 + M and W + M = 10

Out of these choices, only D satisfies above two conditions

If W = 7 then M = 3

I plugged in as well, there is only one combination of m + (m+4) that gives 10 and that is if there were 3 men and 3+4 women.

Answer D.
