A) 18th
B) 16th
C) 14th
D) 12th
E) None of these
Correct Answer: B
Solution :
Explanation: Answer (b) is correct. Since Jack and Cody interchange places, so Jack's new position (15th from left) is the same as Cody's earlier position (7th from right). So, number of children in the queue = \[\left( 15+7 \right)-1=21.\] Now, Cody's new position is the same as Jack's earlier position sixth from left. Therefore Cody's position from the right = \[\left( 21-6+1 \right)\] = 16th position.You need to login to perform this action.
