Correct answer: (D) 13 — Male employees in colleges A and C exceed female employees in colleges B and D by about 13 percent.
Explanation
★Male employees in colleges A and C exceed female employees in colleges B and D by about 13 percent.
★Male in A is 3040 times 13/19, which is 2080.
★Male in C is 2920 times 9/20, which is 1314, so A and C together give 3394.
★Female in B is 3360 times 3/7, which is 1440.
★Female in D is 2760 times 13/23, which is 1560, so B and D together give 3000.
★The difference is 3394 minus 3000, which is 394.
★394 divided by 3000 times 100 is about 13.13 percent, rounded to 13.
