Question
How many persons stay between R and
S? Study the following information carefully and answer the questions given below. Eight persons M, N, O, P, Q, R, S, and T are staying in a building of eight floors but not necessarily in the same order. The ground floor is numbered as 1, the floor just above the ground floor is numbered as 2, and so on till the topmost floor is numbered as 8. Q stays on the 4th floor. Two persons stay between Q and P. S stays adjacent to P. Four persons stay between S and O, who doesn’t stays above Q. Only one person stays between S and N. As many persons stay above M is one less than the persons who stay below M. T stays neither at the bottom nor adjacent to O.Solution
We have, Q stays on the 4th Two persons stay between Q and P.S stays adjacent to P. 
Again we have, Four persons stay between S and O, who doesn’t stays above Q. Only one person stays between S and N. So case-3 gets eliminated.
