Four of the following five are alike in a certain way and hence form a group. Find the one that doesn’t belong to that group.
We have, M lives on an even numbered floor but above fifth floor. Only three persons live between M and L. From the above condition, there are two possibilities 
Again we have, J lives two floors above L. P lives immediately above J. Only one person lives between P and K, who lives above J. 
Again we have, As many floors below K as above O. R lives above Q but below N, who doesn’t live on the topmost floor. So Case1 gets eliminated, hence the final arrangement becomes
