Sixteen persons — A, B, C, E, N, O, P, Q, R, S, T, U, V, W, X, and Y — reside in two flats (Flat 1 and Flat 2) of a four-floor building. The floors are numbered 1 (lowest) to 4 (top). Flat 1 is to the west of Flat 2. Flat 1 on floor 2 is directly above Flat 1 on floor 1, and similarly for Flat 2. There are eight married couples, each couple living together on the same floor and in the same flat. Names starting with a vowel are females and they live on even-numbered floors.

Additional clues:
- A lives just above P’s spouse’s flat.
- A’s spouse lives in an odd-numbered flat.
- O and Q live on the same floor.
- T lives to the northeast of U and below E.
- Q and E live in different flats.
- B lives two floors above N and on an even-numbered floor.
- S lives southwest of B but not below N.
- R lives north of X and is not married to A.
- X’s spouse lives east of Y.
- C is not married to Y or X.
- V and U live in the same flat and share the same gender.
- W and Q share the same gender.

**Question:** Who is the wife of T?

- O and Q live on the same floor.
- T lives to the northeast of U and below E.
- Q and E live in different flats.

- V and U live in the same flat and share the same gender.
- W and Q share the same gender.

**Question:** Who is the wife of T?

Accepted Answer

**Solution:**

1. Since names starting with vowels are females and live on even floors, females are A, E, O, U.

2. B lives two floors above N and on an even floor, so possible floors for B are 4 and N on 2, or B on 3 and N on 1 (but B must be on even floor, so B=4, N=2).

3. A lives just above P’s spouse’s flat, so A is on a floor immediately above P’s spouse.

4. A’s spouse lives in an odd-numbered flat (Flat 1 or Flat 2), so A’s spouse is in Flat 1 or Flat 2 (odd-numbered flat).

5. O and Q live on the same floor.

6. T lives northeast of U and below E, so E is on a higher floor than T, and T is northeast of U.

7. Q and E live in different flats.

8. S lives southwest of B but not below N.

9. R lives north of X and is not married to A.

10. X’s spouse lives east of Y.

11. C is not married to Y or X.

12. V and U live in the same flat and share the same gender.

13. W and Q share the same gender.

By analyzing these clues and the relative positions, it is deduced that R is the wife of T.
