Evelyn, Frank, Grace, and Henry each live on a different floor of a four-story building (floors 1 to 4). 1. Frank lives on a higher floor than Evelyn. 2. Grace does not live on floor 1 or floor 4. 3. Henry lives two floors above Evelyn. On which floor does Grace live?
Floor 2
Since Henry lives two floors above Evelyn, Evelyn must be on floor 1 or 2. If Evelyn were on floor 2, Henry would be on floor 4, leaving floor 1 for Grace—which violates rule 2. Thus, Evelyn is on floor 1, Henry is on floor 3, Frank (higher than Evelyn) is on floor 4, leaving floor 2 for Grace.
