E) None of these
Correct Answer: B
Solution :Explanation: [b] Since Arun and Suresh interchange places, so Arun's new position (13th from left) is the same as Suresh's earlier position (6th from right). So, number of children in the queue\[=\left( 12+1+5 \right)=18\]. Now. Suresh's new position is the same as Arun's earlier position fifth from left. Therefore Suresh's position from the right\[=\left( 184 \right)=14th\].
