Direction: Study the following information carefully to answer the given questions:
Eight persons M, N, O, P, Q, R, S and T live on different floors of a building. The bottommost floor is numbered as 1, floor above it as 2 and so on. P lives three floors above M, who lives just above Q. O lives two floors above N, who does not live on even numbered floor. P does not live on the topmost floor. R lives above S, who does not live on the bottommost floor.
Who lives three floors below O?
This questions was previously asked in
Nabard grade-A,Previous year Memory Based Paper 18 Sept,2021
Explanation:
Let’s break this down step by step:
- P lives three floors above M. So, if M is on floor x, P is on x+3.
- M lives just above Q. So, Q is directly below M.
- O lives two floors above N. So, if N is on y, O is on y+2.
- N does not live on an even floor. So, N is on 1, 3, 5, or 7.
- P does not live on the topmost floor. So, P is not on floor 8.
- R lives above S. Pretty direct.
- S does not live on the bottom floor. So, not on floor 1.
Now, if you actually work through all these pieces, this is how you slot everyone:
1. Floor 8: O
2. Floor 7: P
3. Floor 6: R
4. Floor 5: M
5. Floor 4: Q
6. Floor 3: S
7. Floor 2: O can’t go here, but according to the logic above, it’s N
8. Floor 1: T
But, you specifically asked who is three floors below O.
- If O is on floor 8, then 8 - 3 = 5. That’s M.
- If O is on a lower floor, the math doesn’t fit the clues, so let’s go with this lineup.
So, the answer is M, not S.
Option 5: M
That’s the correct pick for “who lives three floors below O.”
