We are told that the money paid by School A is $6720
Base fee + 12% on the base fee = 6720
Base fee(1+ 12/100) = 6720
Base fee = 6720/112 *100
= 6000
Base fee is same for both School A and B.
School B has an additional 8% on the base fee.
Hence, School B's fee would be : Base fee (1+ 8/100)
= 6000 (1+ 8/100)
= 6480
Differnce b/w school A and School B fees = 6720-6480 i.e 240
B is the correct answer
Base fee + 12% on the base fee = 6720
Base fee(1+ 12/100) = 6720
Base fee = 6720/112 *100
= 6000
Base fee is same for both School A and B.
School B has an additional 8% on the base fee.
Hence, School B's fee would be : Base fee (1+ 8/100)
= 6000 (1+ 8/100)
= 6480
Differnce b/w school A and School B fees = 6720-6480 i.e 240
B is the correct answer

Or you could simply just take the difference 12-8 which is 4%
So 4% of 6000 is 240
Hope it helps!
