The average marks obtained by 40 students of a class is 86. If the 5 highest marks are removed, the average reduces by one mark. The average marks of the top 5 students is
-
- 92
- 96
- 93
- 97
- 92
Correct Option: C
The average marks obtained by 40 students of a class = 86
If the 5 highest marks are removed, the average reduces by one mark , then
Sum of marks of top 5 students = 40 × 86 – 35 × 85
Sum of marks of top 5 students = 3440 – 2975 = 465
∴ Their average = 465 ÷ 5 = 93
