A25
B30
C40 ✓ Correct
D50
Correct answer: (C) 40
Explanation
The answer is 40 percent.
The girls in College F are 21 percent of 24000, which is 5040.
The girls in College A are 15 percent of 24000, which is 3600.
The excess is 5040 minus 3600, which is 1440.
As a percent of 3600, this is 1440 divided by 3600, times 100.
That is 40 percent.
So the answer is 40 percent.
