Show answer & explanation
Correct answer: A
To find the average marks, first convert the percentage scores to actual marks using the maximum marks for each subject.
For Sociology (M.M = 120): Calculate actual marks for each student and sum them up. Total = 588. Average = 588 / 7 = 84.
For IT (M.M = 40): Calculate actual marks for each student and sum them up. Total = 196. Average = 196 / 7 = 28.
