What is the number of employees working in department F who are post-graduate?
A524
B526
C528 ✓ Correct
D530
Correct answer: (C) 528
Explanation
The number of post-graduate employees in department F is 528, so the answer is 528.
The company has 8000 employees in all.
Department F holds 21 percent of them, which is 1680 employees.
The graduates in the company are three-fifths of 8000, which is 4800.
Department F holds 24 percent of these graduates, which is 1152.
So the post-graduates in F are 1680 minus 1152.
That equals 528, so the answer is 528.
