M, N, O, P and Q are standing in a queue to place their order in a restaurant. Only P is standing between M and Q. O is ahead of only N. Who is standing second in the line if there is no other person in the queue?

P

Answer: P

In this question first place N at the last place and put O only before N. Now place P at the second place. The place of M and Q is not fixed so we will put them both on the first and the third place
