What are the average marks obtained by all the seven students in Physics? (rounded off to two digit after decimal)
Answer: Option
Explanation:
Average marks obtained in Physics by all the seven students


+ (80% of 120) + (85% of 120) + (65% of 120) + (50% of 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.

The correct answer should be 74.29 as per average rule.

How can it be possible, max marks of history & comscience are less than the marks obtained by the students?

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.

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.

Why we are taking 90% of 120?
