Answer :
If full then the stadium could have held 60000 people over 3 days.
It really held 17563+18126+16618 over the 3 days = 52307 people. To work out the difference 60000 - 52307 = 7693
Therefore 7693 seats were free over the 3 day period and so 7693 more people could have attended the concerts overall
