Explanation:

Alright, let’s break this puzzle down step by step:

- There are 8 people, 4 floors, 2 flats per floor. Flat 1 (west), Flat 2 (east).

- B is above C, with 2 floors between them, and they are in different flats.

- So, if C is on Floor 1, B is on Floor 4 (not in same flat). Or C (2) & B (4), or C (1) & B (3) — but spacing is 2, so only C (1) & B (4) or C (2) & B (4)

- F is immediately above C. That means F and C are in the same flat, consecutive floors.

- G is on the fourth floor, and nobody is west of G, so G is in Flat 1 (west), Floor 4.

- C can’t be on Floor 3, because then F would be Floor 4, but G is already in Flat 1, Floor 4.

- H doesn’t live on the first floor.

- A is west (Flat 1) of D and on an odd-numbered floor.

So, let’s start from the top — Floor 4, Flat 1: G. That means B can only be in Floor 4, Flat 2.

C, being two floors below B, must be on Floor 1, Flat 1 or 2 (since B is Floor 4 Flat 2, C must be Floor 2 Flat 1). But F is just above C, so F is Floor 3, Flat 1. So, B (4,2), F (3,1), C (2,1). Done.

A lives west of D; that means A (Flat 1), D (Flat 2) on same floor. Also, A is on an odd-numbered floor.

Since Flat 1 on Floor 1 is still open, but H does not live on Floor 1, let's try A (1,1), D (1,2), but H can’t be here. Let's check other possible placements for A/D. Try A (3,1), but F is already (3,1). Try A (1,1), but that also bumps into H's rule. Let's mark what we've got so far:

Floor 4: G (1), B (2)

Floor 3: F (1),

Floor 2: C (1),

Floor 1:

That leaves Floor 3, Flat 2; Floor 2, Flat 2; Floor 1, Flat 1; Floor 1, Flat 2 for E, D, H, and A.

A & D must be same floor, odd floor, A west of D. Odd floor options are 1 and 3. Floor 3 Flat 1 is taken (F), so only option is Floor 1, A (1,1), D (1,2).

So, Floor 1, Flat 1: A

Floor 1, Flat 2: D

Now, H is not on Floor 1, so H must be Floor 2, Flat 2 or Floor 3, Flat 2.

E gets the remaining spot.

Overall layout:

Floor 4: G (1), B (2)

Floor 3: F (1), ____ (2)

Floor 2: C (1), ____ (2)

Floor 1: A (1), D (2)

Spaces left: Floor 3, Flat 2 and Floor 2, Flat 2 for E/H.

So, H can be (3,2) or (2,2), and E the other.

Let’s check if any clues contradict E being on Floor 1, Flat 2:

You asked: Which flat/floor is E in?

Option 1 is Floor 1, Flat 2.

But according to what we've laid out, D is already on Floor 1, Flat 2, so E cannot be on Floor 1, Flat 2.

Correct answer:

- If H is on Floor 3, Flat 2 ? E will be on Floor 2, Flat 2 (Option 5)

- If H is on Floor 2, Flat 2 ? E will be on Floor 3, Flat 2 (Option 3)

Since no more constraints pin H down, but either way, E is never on Floor 1, Flat 2.

So, the Floor/Flat combination for E is not Option 1.

Here’s the clear map of solutions:

- Floor 4: G (1), B (2)

- Floor 3: F (1), H/E (2)

- Floor 2: C (1), E/H (2)

- Floor 1: A (1), D (2)

E must be in either Floor 2, Flat 2 (Option 5) or Floor 3, Flat 2 (Option 3)—whichever one H is not in.

?? Option 3: Floor 3 Flat 2 is a possible answer for E.

?? Option 5: Floor 2 Flat 2 is also possible for E.

But—never Floor 1, Flat 2.

That’s the logic, step by step.
