Question

In a queue, A is 18${}^{th}$ from the front while B is 16${}^{th}$ from the back. If C is 25${}^{th}$ from the front and is exactly in the middle of A and B, then how many persons are there in the queue?

• A. 45
• B. 46
• C. 47
• D. 48
• E. None of these

Answer 1

The correct option is C

47

A is 18${}^{th}$ from the front and C is 25${}^{th}$. No. of persons between A and C = 6.

Since C is exactly in the middle of A and B, so number of persons between C and B = 6.

$\therefore$No. of people in the queue = 17+1+6+1+6+1+15 = 47
