Ten people—J, K, L, M, N, O, P, Q, R, and S —live in a building with five floors and two flats (Flat 1 and Flat 2) on each floor. The floors are numbered from 1 to 5 (1 being the lowermost floor and 5 being the topmost floor).
Note I: Each floor has two flats viz., Flat-1 and Flat-2, where Flat 1 is to the west of Flat 2.
Note II: Flat 1 of floor 2 is immediately above Flat 1 of floor 1 and immediately below Flat 1 of floor 3 and so on. Similarly Flat 2 of floor 2 is immediately above Flat 2 of floor 1 and immediately below Flat 2 of floor 3 and so on.
Note III: The area of each flat is equal.
Note IV: Only two persons live on each floor and only one person lives in each flat.
L lives on an even -numbered floor in Flat -1. P lives in Flat -2 of the topmost floor. N lives west of Q. N lives on a floor immediately below the L’s floor. K and R live on the same named flat. K and L lives in a different named flat. Only one floor is between K and O. K lives below O. S lives to the west of P. M lives immediately below O, but not in the same named flat. One floor between J’s floor and L’s floor.
Who lives in Flat 1 on the topmost floor?
Correct Answer :
S
Solution :
To find out who lives in Flat 1 on the topmost floor, we can analyze the given clues step-by-step:
Step 1: Understand the building layout
The building has five floors numbered 1 to 5 from bottom to top.
Each floor has two flats: Flat 1 (on the west) and Flat 2 (on the east).
Step 2: Position the residents on the topmost floor
We are given that: "P lives in Flat -2 of the topmost floor."
Since the topmost floor is Floor 5, P is located at Floor 5, Flat 2.
We are also given that: "S lives to the west of P."
Since Flat 1 is located immediately to the west of Flat 2 on any given floor, the person living to the west of P on the 5th floor must be in Flat 1 of Floor 5.
Step 3: Determine the final answer
Since S lives to the west of P, S must live in Flat 1 on the 5th (topmost) floor.
