Question

In a row of boys, Sachin is eleventh from the left and Raj is seventh from the right. If they interchange their places, Sachin becomes sixteenth from the left. How many boys are there in the row?
1. 21
2. 22
3. 23
4. 24

Answer 1

Correct Answer - Option 2 : 22

In a row of boys Sachin is eleventh from the left and Raj is seventh from the right.

Sachin becomes sixteenth from the left end after interchanging his position.

Sachin's position changes from 11th to 16th from the left after interchange, it means 15 boys are standing from his left side.

Now, Sachin is at Raj’s position which is 7th from the right side.

That means 6 boys are standing to his right.

So, total number of boys in the row = 15 + 6 + 1

= 22 

Hence, ‘22’ is the correct answer.
