Question 1
4 people (Kavita, John, Preeti, Matthew) live in a 6-floor building (floors 1 to 6). Not all floors are occupied.
Based on these clues:
• Kavita lives above Matthew
• Kavita and John are exactly 2 floors apart
• Floor 1 is vacant
• Kavita and Matthew are exactly 1 floor apart
• Preeti lives immediately above John
On which floor does John live?
The unique arrangement (floor: person) is: {2: 'Matthew', 3: 'Kavita', 5: 'John', 6: 'Preeti'}.
