Hi,
Let the maximum mark in each subject be 100. Hence, total marks (maximum) is 500, as there are 5 subjects.
Candidate obtained 3/5 of total marks, hence 3/5 of 500 = 300.
Let His individual marks were 6x, 7x, 8x, 9x and 10x.
So, total marks will be 6x + 7x + 8x + 9x + 10x = 40x
40x = 300.
x = 300/40 = 7.5
His marks are 6x, 7x, 8x, 9x and 10x.
So marks are 45, 52.5, 60, 67.5, 75
so papers where he got more than 60% of marks are
67.5, 75 so two subject
