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. 49
• B. 52
• C. 51
• D. 50

Answer 1

Answer:

A. 49

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:
   $50 - 1 = \mathbf{49}$
