This problem can easily confuse people who are easily confused.
It makes absolutely no difference how many of each kind of coin he had. The only important fact is that he had (16 + 28 + 32 + 4) = 80 coins all together.
He sold 15% of them. ' 15% ' means ' 0.15 ', and ' of ' means ' times '.
0.15 x 80 = 12 coins sold.

George has a total of 80 coins and sold 15% of them, which equals 12 coins. This was calculated by first finding the total number of coins and then taking 15% of that total. Therefore, George sold 12 coins in total.
