Question 1
7 people (Layla, Skyler, Taylor, Rohan, Lily, Hazel, Ritu) live on floors 1 to 7. The following mathematical and logical constraints apply:
Based on these clues:
• Rohan and Ritu are exactly 3 floors apart
• The difference between floor numbers of Rohan and Lily is 5
• Skyler lives at most 2 floors above Hazel
• The product of floor numbers of Taylor and Hazel is 21
On which floor does Lily live?
The unique arrangement (floor: person) is: {1: 'Rohan', 2: 'Layla', 3: 'Hazel', 4: 'Ritu', 5: 'Skyler', 6: 'Lily', 7: 'Taylor'}.
