Mohan's rank in a class of 40 students is 27th, then what is his rank from the last?

14th

The correct answer is Option (3) → 14th

To find a person's rank from the opposite side, we use the following standard formula:

$\text{Rank from Last} = (\text{Total Students} - \text{Rank from Top}) + 1$

1. Identify the given values:

• Total Students ($N$): 40
• Rank from Top ($R_{top}$): 27

2. Apply the formula:

$\text{Rank from Last} = (40 - 27) + 1$

$\text{Rank from Last} = 13 + 1$

$\text{Rank from Last} = \mathbf{14\text{th}}$
