Out of a total of 1,000 employees at a certain corporation, 52 percent are female and 40 percent of these females work in research. If 60 percent of the total number of employees work in research, how many male employees do NOT work in research?
(A) 520
(B) 480
(C) 392
(D) 208
(E) 88

E.

It helps to draw a double set matrix for this problem. We get F=520 and M=480. R=600 and NR(not research)=400. F&R=.4(520)=208.

And we get F&NR=312. So 400-312=88.

Agree on E. Gotta be careful when you are filling the DSM that 40% of the females who work in research is 20.8% of the 1000 employees, and not precisely 40%

E.

Total = 1000
F = 520, M = 480
F in Research = 208, F not in Research = 312
Total in Research = 600
Total not in Research = 400
Total men not in research = 400-312 = 88

Asdert raises a good point.
