Correct option is D
As we know-
Total students=Position from the top+Position from the bottom−1
Given:
Selvam's position from the top = 9
Selvam's position from the bottom = 38
Now, substituting the values into the formula:
Total students=9+38−1=46
The total number of students in the class is 46.
So, the correct option is (d) 46.
