💡 Analysis & Explanation

Floor Constraint Parsing ▼

A six-story building houses six individuals. We analyze the explicit constraints: 'Only M lives above N' means N is on floor 5, making M the absolute top on floor 6.

Positioning Intermediate Blocks ▼

'Z lives immediately below N' places Z on floor 4. The statement 'Only P lives below O' means O is on floor 2, making P the absolute bottom on floor 1.

Filling the Void ▼

Mapping the known residents (M=6, N=5, Z=4, O=2, P=1) leaves exactly one unoccupied floor, which is floor 3. The only remaining person without an assigned floor is Y. Thus, Y must occupy floor 3.

Conclusion ▼

The person residing on floor number 3 is Y.
