In a Hindi test of 100 marks, 11 students got 78 marks, 7 students got 80 marks, 5 students got 82 marks, and 2 students got 86 marks. What was the average mark in Hindi?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 80.
Total marks = (11 × 78) + (7 × 80) + (5 × 82) + (2 × 86) = 858 + 560 + 410 + 172 = 2000
Total students = 11 + 7 + 5 + 2 = 25
Average marks = 2000/25 = 80
