💡 Analysis & Explanation
Fixing Known Positions ▼
The floors are numbered strictly 1 to 6 from bottom to top. It is explicitly stated that O lives on floor 4. Furthermore, Y lives immediately below O, firmly placing Y on floor 3.
Placing Correlated Entities ▼
The rule states only two people live between O (floor 4) and P. The only mathematically possible position for P is floor 1, leaving floors 2, 5, and 6 empty.
Resolving Remaining Slots ▼
Only M lives strictly between O (floor 4) and N. This dictates they occupy consecutive floors. Since 4 is occupied by O, M must be on floor 5, placing N on floor 6.
Identifying the Missing Entity ▼
With floors 1, 3, 4, 5, and 6 filled, the sole remaining person is Z, who must occupy the single vacant floor, which is floor 2.
Conclusion ▼
Based on the logical deduction, Z lives on floor numbered 2.
