Direction (1-5): Study the following information carefully and answer the questions given below.
Nine persons – L, M, N, O, P, Q, R, S and T are staying in a nine-storey building, but not necessarily in the same order. The lowermost floor is numbered as 1, the floor just above is numbered as 2 and so on.
P stays on an odd numbered floor but neither on the topmost floor nor on the lowermost floor. Only two persons stay between P and L. M stays two floors above L. Q stays immediately below M. As many floors between Q and R as between R and S. N stays above O. The number of floors above N is the same as the number of floors below O.
Q1: Who among the following stays on the fifth floor?
(a) The one who stays three floors below N
(b) S
(c) The one who stays immediately above R
(d) P
(e) None of these
Ans: (a)
Sol: 

We have,

• P stays on an odd numbered floor but neither on the topmost floor nor on the lowermost floor.
• Only two persons stay between P and L.
• M stays two floors above L.

From the above conditions, there are three possibilities

Again we have,

• Q stays immediately below M.
• As many floors between Q and R as between R and S.

Again we have,

• N stays above O.
• The number of floors above N is the same as the number of floors below O.

From the above conditions, case 2 and case 3 get eliminated. Hence, case 1 shows the final arrangement.

Q2: Which of the following statements is/are true with respect to the final arrangement?
