Question

In a queue, A is eighteenth from the front while B is sixteenth from the end. If C is twenty-fifth from the front and is exactly in the middle of A and B, then how many persons are there in the queue?

Accepted Answer

A. A is 18th from the front and C is 25th from the front. Number of persons between A and C = $25 - 18 - 1 = 6$. Since C is exactly in the middle of A and B, there must also be 6 persons between C and B. Position of B from the front = $25 + 6 + 1 = 32$. Since B is 16th from the end, total persons in the queue = $32 + 16 - 1 = 47$.
