It's simple.
You can add all the marks obtained in physics by 7students, you will get 520 of 120.
Here of 120 mean: result/100 * total mark.
120/100 * 520 = 624
624/7 = 89.14.

520/7 = 74.28
74.28 * 120 = 8913.6
8913.6/100 = 89.136
= 89.14.
74.28 * 120 = 8913.6
8913.6/100 = 89.136
= 89.14.

As they have given the percentage of marks, we need to calculate the actual marks, so 90% means, 90/100 (120). From this, we get the actual marks scored.

520 marks are received for 7 students out of 840 marks.
Average marks received are 74 approximately.

As per my solution;
First, l am calculating to the total % in physics 120% total marks 7.
(90+80+70+80+85+65+50)/7 * 120 = 520/7 * 120 = 74.3 * 120 = 89.16.
