Solving the Seven-Floor Building Logic Puzzle
This solution determines the floor number for person A by logically deducing the position of each resident based on the provided clues.
Key Constraint Deductions
- Two people above C: With 7 floors, this means C must be on floor 5 (Floors 6 and 7 are above).
- Two people between C and E: C is on floor 5. To have two people between them, E must be on floor 2 (Floors 3 and 4 are between C and E).
- B immediately above E: Since E is on floor 2, B must be on floor 3.
- D immediately below F: F and D are neighbours, with F above D. They form a block (F, D).
- A not on floor 1: A cannot occupy the lowest floor.
Step-by-Step Floor Assignment
- Current assignments: Floor 5: C, Floor 3: B, Floor 2: E.
- Consider the (F, D) block. They need two adjacent empty floors. The available pairs are (7, 6) and (4, 3 - blocked by B), (3, 2 - blocked by B & E), (2, 1 - blocked by E). The only valid adjacent empty slots are floors 7 and 6. Thus, F is on floor 7 and D is on floor 6.
- Remaining people: A and G. Remaining floors: 4 and 1.
- A does not live on floor 1. Therefore, A must live on floor 4.
- G lives on the remaining floor, floor 1.
Final Floor Layout
The deduced floor arrangement is:
| Floor 7 | F |
| Floor 6 | D |
| Floor 5 | C |
| Floor 4 | A |
| Floor 3 | B |
| Floor 2 | E |
| Floor 1 | G |
Based on this arrangement, A lives on floor number 4.
