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?

A49

B52

C51

D50

Answer:

A. 49

Read Explanation:

The total number of students in the class is 49.

To find the total number of students when a single person's rank is known from both ends, you use this formula:
$\text{Total Students} = (\text{Rank from Top} + \text{Rank from Bottom}) - 1$

  1. Add the two ranks together:
    $18 + 32 = 50$

  2. Subtract 1:
    $50 - 1 = \mathbf{49}$
