Question 1
5 people (Neha, Jay, Sam, Riley, Susan) live in a 8-floor building (floors 1 to 8). Not all floors are occupied.
Based on these clues:
• Floor 2 is vacant
• Neha lives on floor 6
• Sam and Riley are exactly 4 floors apart
• Riley lives immediately below Neha
• Neha lives immediately below Susan
• Jay and Sam are exactly 2 floors apart
On which floor does Neha live?
The unique arrangement (floor: person) is: {1: 'Sam', 3: 'Jay', 5: 'Riley', 6: 'Neha', 7: 'Susan'}.
