​​Eight people, P, Q, R, S, T, U, V and W. live on different floors of the same building. The lowermost floor in the building is numbered 1, the floor above it is numbered 2 and so on till the topmost floor is numbered 8.

Exactly two people live between P and T. Q lives immediately above R, on an even numbered floor. P lives on the topmost floor. S lives in one of the floors above T on an odd numbered floor. Only four people live between S and U. W lives on the lowermost floor. Who lives on the sixth floor?

Given: Eight people: P, Q, R, S, T, U, V, and W live in the same building, which has 8 floors.

Floor numbering:

Floor 1 = Lowermost

Floor 8 = Topmost

P lives on the topmost floor (Floor 8).

Exactly two people live between P and T.

Q lives immediately above R, and both are on even-numbered floors.

S lives on one of the floors above T, and S lives on an odd-numbered floor.

Only four people live between S and U.

W lives on the lowermost floor (Floor 1)

Thus, correct option is (b).
