The question gives us a ratio and two percentages, so let's solve the question using a
weighted average.
(# of Company A employees) : (# of Company B employees) =
2 :
1 % female employees in Company A =
64%% female employees in Company B =
52%[
2x (
64) +
x (
52)] /
3x(
128x +
52x) /
3x180 /
3 =
60 ----->
60% of employees at both companies are female
