Question 1
5 people (Divya, Riley, Susan, Ritu, Hazel) live on floors 1 to 5. The following mathematical and logical constraints apply:
Based on these clues:
• Divya lives immediately below Hazel
• The sum of floor numbers of Divya and Riley is 5
• Riley does not live on floor 3
• Ritu lives on an even-numbered floor
On which floor does Riley live?
The unique arrangement (floor: person) is: {1: 'Riley', 2: 'Ritu', 3: 'Susan', 4: 'Divya', 5: 'Hazel'}.
