Question

In a row, Amit is 12th from the left and Sunil is 15th from the right. After they interchange their positions, Amit becomes 17th from the left. What is the total number of persons in the row?

• A. 30
• B. 29
• C. 31
• D. 32

Answer 1

Answer:

C. 31

Amit is 12th from the left. After swapping with Sunil, Amit takes Sunil’s position and becomes 17th from the left.

So, Sunil’s original position from the left = 17th.

Sunil is also 15th from the right.

Total number of persons in the row:
$\text{Total} = \text{Position from left} + \text{Position from right} - 1$
$= 17 + 15 - 1 = 31$

Final Answer: 31 persons
