Two third of the faculty members of a department are female. Twelve of the male faculty members are unmarried, while 60% of them are married. What is the total number of faculty members in the department?
Solution
Correct Answer: Option A
40% (married) of total male = 12
100% of total male = 12*100/40
= 30
If total number of faculty = x
then, total number of male faculty = x - 2x/3 = (3x-2x)/3 = x/3
Thus,
x/3 = 30
x = 30*3 = 90
