Question
Four of the following five are a like in a certain way
based on the given arrangement and thus form a group. Which is the one that does not belong to that group? Study the following information carefully and answer the question given below: There are eight people M, N, O, P, Q, R, S and T are living in a 8 floor Building on different floors from top to bottom (such as ground floor is numbered as 1 and top floor is numbered as 8) but not necessarily in the same order. R lives on an odd number floor but does not live on 3rd floor. T lives immediate below R. More than two persons live between S and T. There are six persons live between M and S. P lives immediate above Q but live below N. O does not live above R. Q does not live immediate above S.Solution
1. R lives on an odd number floor but does not live on 3rd floor 2. T lives immediate below R. 
3. More than two persons live between S and T. 4. There are six persons live between M and S. 
5. P lives immediate above Q but live below N. 6. O does not live above R. 7. Q does not live immediate above S. 
So CASE2 is cancelled out.
