The average of the number of boys studying in Colleges A, B and C is
A4900
B4700
C4400
D4800 ✓ Correct
Correct answer: (D) 4800
Explanation
The answer is 4800.
In College A the boys are 6000 students minus 3600 girls, which is 2400.
In College B the boys are 5400 minus 2880, which is 2520.
In College C the boys are 13800 minus 4320, which is 9480.
Their sum is 2400 plus 2520 plus 9480, which is 14400.
The average is 14400 divided by three, which is 4800.
So the answer is 4800.
