Five persons P, Q, R, S and T live on different floors of a five-storey building (ground floor = 1, top floor = 5). P lives on an even-numbered floor. Q lives immediately above P. S lives below P. R lives above Q but not on the top floor. Who lives on the top floor?

Correct answer: A

Explanation

S below P forces P = 2 and S = 1; then Q = 3, R = 4 (above Q, not on top), leaving T on floor 5.
