Manish is eighteenth from the right end and Rahul is fifth from the left end in a row of boys. If there are seven boys between Manish and Rahul, how many boys are there in the row?

30

The correct answer is Option (2) → 30

Given:

• Manish is 18th from the right → position from the left = $N - 18 + 1 = N - 17$
• Rahul is 5th from the left
• There are 7 boys between them

Step 1: Find the difference in their positions

$|(N - 17) - 5| - 1 = 7$

$|N - 22| = 8$

Step 2: Solve

$N−22=8⇒N=30$
