Question

​In a class of students. Radhika is 18th from the top and 32nd from the bottom. What is the total number of students in the class?

A.

52

B.

49

C.

50

D.

51

Correct option is B

Given:
Radhika's position from the top = 18
Radhika's position from the bottom = 32
Substitute these values into the formula:
Total number of students = Position from the top + Position from the bottom−1
Total number of students=18+32−1=49
So, the total number of students in the class is 49.
Thus, correct option is (b).
