1. Two third of the faculty members of a department are female. Twelve of the male faculty members are unmarried, while 60% of them married. What is the total number of faculty members in the department?
- A. 90
- B. 90
- C. 90
- D. 90
Answer: Option A
Explanation:
Unmarried male faculty members are (100 - 60) = 40% of all male faculty members.
Now, 40% of male faculty = 12
So, Number of total male faculty members = 12 x 100 / 40 = 30.
Again, male faculty members are (1 - 2/3) = 1/3 of all faculty members.
Or, 1/3 of all faculty members = 30
So, number of total faculty members = 30 x 3 = 90.
