Reasoning PYQs

Given: Ten persons – Q, R, S, T, U, V, W, X, Y, and Z – live in a five-storey building. The ground floor is numbered 1, the floor above it is numbered 2, and so on up to the topmost floor numbered 5. Each floor has two flats, namely Flat-1 and Flat-2.

Flat-1 is to the west of Flat-2. Flat-1 of any floor is immediately above Flat-1 of the floor below it and immediately below Flat-1 of the floor above it. The same applies to Flat-2.

1. T lives three floors above Y in a different named flat.
2. The one who lives to the east of T lives two floors above S.
3. X lives just to the north-east of S. 

Here, there are two cases, i.e. Cases 1 and 2.

 

4. One floor is between the floors of X and Q.
5. Q and T live in the same flat.
6. W lives immediately below Q.
7. V lives three floors above W in the same named flat. 

Case 1 gets eliminated because there is no place for V.

 

8. Z lives above U, who doesn’t live in the bottom-most floor. Hence, the final arrangement:

 

V and X lives on the same floor.

Hence, the correct answer is ‘V and X’.
