Why this answer is correct
Given information:
Eight people: P, Q, R, S, T, U, V and W.
4 floors and 2 flat.
Flat 1 is immediate left of flat 2.
-
P lives on an odd-numbered floor but he does not live on the ground floor.
-
R and S live on the same floor but above the floor on which P lives.
| Floors / Flats | CASE 1 | CASE 2 | ||
|---|---|---|---|---|
| Flat 1 | Flat 2 | Flat 1 | Flat 2 | |
| 4 | S/R | R/S | S/R | R/S |
| 3 | P | P | ||
| 2 | ||||
| 1 |
-
V lives on an even-numbered floor just above Q in the same flat on different floors.
-
P and V do not live in the same flat on different floors.
| Floors / Flats | CASE 1 | CASE 2 | ||
|---|---|---|---|---|
| Flat 1 | Flat 2 | Flat 1 | Flat 2 | |
| 4 | S/R | R/S | S/R | R/S |
| 3 | P | P | ||
| 2 | V | V | ||
| 1 | Q | Q |
-
Q and R live in the same flat on different floors.
-
U lives below the floor on which V lives.
-
W does not live with P on the same floor. (Hence W lives on 2nd floor)
-
T does not live to the immediate right of P.
(In case 1 T lives immediate right of P. So, Case 1 is invalid)
| Floors / Flats | CASE 2 | |
|---|---|---|
| Flat 1 | Flat 2 | |
| 4 | R | S |
| 3 | T | P |
| 2 | V | W |
| 1 | Q | U |
Final Solution:
| Floors / Flats | CASE 2 | |
|---|---|---|
| Flat 1 | Flat 2 | |
| 4 | R | S |
| 3 | T | P |
| 2 | V | W |
| 1 | Q | U |
Q and U live on a floor 1.
Hence, the answer is Q, U.
