Question
Who among the following lives on flat at 2 of floor no.
4? Answer the questions based on the information given below. Ten persons O, P, Q, R, S, T, U, V, W, and X are living on five floors (numbered 1 to 5) of a building. There are two flats on each of the five floors i.e. flat 1 and flat 2. Flat 1 is to the west of flat 2, where the bottommost floor is numbered as 1 and the floor above it is numbered as 2, and so on. O lives three floors above V, who lives southeast of W, who lives on an even-numbered floor. Both O and V don’t live in the same numbered flat. R and U live on the same numbered floor, but not immediately above or immediately below the floor on which W lives. Only one floor between U and P, who lives northeast of Q. T lives above S, but not lives above X. Both X and S live in the same numbered flat. R lives on an odd numbered flat.Solution
O lives three floors above V, who lives southeast of W, who lives on an even numbered floor. Both O and V don’t live in the same numbered flat. R and U live on the same numbered floor, but not immediately above or immediately below the floor on which W lives. Only one floor between U and P, who lives northeast of Q. T lives above S, but not lives above X. R lives on an odd numbered flat. 
Both X and S live in the same numbered flat. So the final arrangement becomes:
