A student got 90 % marks in an exam of 500 marks. If marks of Physics are printed 94 instead of 72, then the true % obtained by the student will be

OPtion

1) 89%
2) 88%
3) 94%
4) 92%
5) 87%
6) 80%
7) 86%
8) 83%
9) 85%
10) None of the above

total difference of marks = 94-74 = 20
5 marks = 1% (total marks = 500 so 1 % = 500/100 = 5 marks)
20/5 = 4% so true % = 90-4 = 86%
