Question

In a queue of children, Arunima is seventh from the left and Sukumar is sixth from the right. When they interchange their places among themselves, Arunima becomes fourteenth from the left. Then, what will be Sukumar's position from the right?

• A. 8^th
• B. 13^th
• C. 15^th
• D. 16^th
• E. None of these

Answer 1

The correct option is B

13^th

Since Arunima and Sukumar interchange places, so Arunima’s new position (14${}^{th}$ from left) is the same as Sukumar’s earlier position (6${}^{th}$ from right).

So, number of children in the queue = (13+1+5) = 19.

Now, Sukumar’s new position is the same as Arunima's earlier position seventh from left.

$\therefore$Suresh’s position from the right = (19 - 6) = 13${}^{th}$.
