C) 95
D) 96
E) 97
Correct Answer: B
Solution :
| Average marks abtained by 40 students = 86 |
| Total mark of 40 students \[=40\times 86=3440\] |
| After removing top 5 students marks. |
| Remaining students \[=40-5=35\] |
| New average \[=86-1=85\] |
| Total marks remaining 35 students |
| \[=35\times 85=2975\] |
| Now, total marks of top 5 students |
| \[=3440-2975\] |
| \[\therefore \] Average of top 5 students \[=\frac{465}{5}=93\] |
