Question
If P is related to T and Q is related to R in a certain
way, then who among the following person is related to O? Study the following information carefully and answer the questions given below. Eight persons- O, P, Q, R, S, T, H and J are living on eight different floors of the building but not necessarily in the same order. The lowermost floor is numbered as one and the floor immediately above it is numbered as 2 and so on. Only two persons live between O and S who lives three floors below P. H lives on an odd-numbered floor but above S. T lives adjacent floor of H. The number of persons living below T is the same as the number of persons living above Q. J lives above R but one of them lives on an odd-numbered floor.Solution
We have, Only two persons live between O and S. S lives three floors below P. From this condition, there are two possibilities 
Again we have, H lives on an odd-numbered floor but above S T lives adjacent floor of H 
Again we have, The number of persons living below T is the same as the number of persons living above Q. J lives above R but one of them lives on an odd-numbered floor. From this condition, Case2 gets eliminated. Case1 shows the final arrangement.
