What are the average marks obtained by all seven students in Physics? (Rounded off to two digits after the decimal)

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. 89.14.

Total of scores in physics = (80 + 90 + 70 + 80 + 65 + 85 + 50)% of 120

⇒ 520% of 120 = 624

Required Average = 624/7 = 89.14
