IBPS PO Reasoning: Seating Arrangement and Floor Puzzle questions with solutions

Q1. Passage: There are ten floors in a building. Ten persons P, Q, R, S, T, U, V, W, Y, and Z live on different floors of the building. The lowermost floor is numbered 1; the floor above it is numbered 2 and so on. Z lives on the sixth floor. Three persons live between Z and U. P lives immediately below U. Five persons live between P and Q. V lives on an even floor and lives immediately above R. W lives on one of the floors below R but not immediately below R. W is not living on an odd-numbered floor and lives above O's floor. Y lives above T's floor and below S's floor. S does not live on an even floor. Who lives on the lowermost floor?

1. U
2. T
3. V
4. R

Answer: T

Using Z on floor 6 and three persons between Z and U, U must be on floor 10 or 2. Since P is immediately below U and five persons are between P and Q, the valid placement leads to a consistent arrangement only when U is on floor 10 and P on 9. Continuing with the remaining clues fixes the other persons, leaving T on the lowermost floor.
