Finding the Total Number of Students in a Class

Given information: Harini ranks 13th from the top and 28th from the bottom in a class.

To find: The total number of students in the class.

Solution:

Let us assume that the total number of students in the class is "N".

From the given information, we can conclude that:

- The number of students ahead of Harini in the class = 12 (as Harini ranks 13th from the top).
- The number of students behind Harini in the class = 27 (as Harini ranks 28th from the bottom).

Therefore, we can say that:

- The total number of students in the class = (number of students ahead of Harini) + (number of students behind Harini) + 1 (for Harini)

=> N = 12 + 27 + 1

=> N = 40

Therefore, the total number of students in the class is 40.

Answer: Option (B) 40.
