Question
In which floor and flat does S live?
Study the following information carefully and answer the questions given below: There are nine persons – P, Q, R, S, T, U, V, W and I are living on 3 floors (numbered 1 to 3) of a building. There are three different flats on each of the three floors. Flats are X, Y, & Z such that Flat X is exactly to the west of flat Y and flat Y is exactly to the west of flat Z. Flat X of floor 2 is exactly above the Flat X of floor 1 and so on. V lives just above R whereas V lives in Flat Z. P and R doesn’t live on the same floor. U lives just above P but not in the same flat. U and W live in the same flat, whereas W lives east of T. Only one person lives between I and Q, and they are living on the same floor. The one who lives west of S lives in the same flat in which I lives.Solution
V lives just above R whereas V lives in Flat Z. 
U lives just above of P but not in the same flat. U and W live in the same flat, whereas W lives east of T. P and R doesn’t live on the same floor. 
Only one person lives between I and Q, and both are living on the same floor. Case II and II (p) are invalid because there is no place for I and Q. The one who lives west of S lives in the same flat in which I lives.Case I shows the final arrangement.
