Thanks Everyone It clear my Doubt.
1/7 x [(90% of120) +(80% of120) +(70% of120)+(80% of120) + (85% of120) + (65%of120) + (50% of120)].
=1/7x(90+80+70+80+85+65+50)% of 120].
=1/7x [ 520% of 120 ] i.e 1/7 * [520/100*120].
1/7*[52*12] = 624/7.
= 89.14.

I am replying for the previous comment, I am in small confusion of (%) sorry for that comment so the right answer is 89.14.

The original form of 520% of 120 is 520*100/120.

Why we are taking 90% of 120?
Fareen Khan said:

Because the actual marks obtained by students are not given, marks are given in (%) and Ayush got 90 (%) marks out of 120 marks.
So we need to calculate 90(%) of 120 to get the marks obtained by Ayush in physics.

In question, it is not given anywhere that the marks are in %. Maximum marks (Subject) is only mentioned. So the solution must be 520/7 = 74.28.

How can it be possible, max marks of history & com-science are less than the marks obtained by the students?
Shubham said:

The correct answer should be 74.29 as per average rule.
