You can put this solution on YOUR website! in First 7 exams
average = 56 %
so total marks available in first 7 exams = 700
Flora scored 56*7
in 8 exams
If average is 60%
Total marks available in 8 exams = 800
Flora should score 60*8 in total
Total score for 7 exams = 392
Total score required for 8 exams = 480
marks to be scored in 8th exam = 480 - 392
= 88
