Correct Answer - Option 3 : 31
Given:
Sneha's average marks in 16 exams = 25
Priyal's average marks in 12 exams = 23
Formula used:
Average marks in n exams = Sum of the marks/n
Calculation:
As per the question;
Sneha's average marks in 16 exams = Priyal's average marks in 16 exams
⇒ 25 = 23 + Average marks in 4 exams
Sum of Sneha's marks in 16 exams = 25 × 16 = 400
Sum of Priyal's marks in 12 exams = 23 × 12 = 276
Sum of Priyal's marks in remaining 4 exams in order to match with Sneha's performance = 400 - 276
⇒ 124
∴ Average marks of Priyal in remaining 4 exams = 124/4
⇒ 31
