In Computer Science Max Mark is 40, But Student Marks is given up to 90. How can we get 90 marks even Max mark is 40 only.

Easy way:-
((Total Marks)/(No. of Students))*(outoff marks).
i.e. (520/7)*120 = 89.14.
[520*120]/7 =86.14.
((Total Marks)/(No. of Students))*(outoff marks).
i.e. (520/7)*120 = 89.14.
[520*120]/7 =86.14.

Simple= 520/100*120=624.
You can try to first divisible get 0 or canceled and got multiply 12*52=624.

80% of 120 is 96 not 90.

We can 1/7 * (90+80+70+80+85+65+50).
= 1/7 * 520.
= 74.2857 * 1.2 (full mark 120%) = 89.14.
= 1/7 * 520.
= 74.2857 * 1.2 (full mark 120%) = 89.14.

@Akshata.
It's written 'percentage of marks' not just marks and yes 90% of 120 is not 90 but they have taken " % of 120" as common and grouped the percentage marks together for addition in the second step.

@All.
There is a big mistake in the question. That is, all the marks obtained by a student (Not the marks percentage) but in the answer, they are using them as percentage marks! How? Explain me clearly.
