Explanation:
- Z lives on the 6th floor.
- Three floors between Z and U mean U is on the 10th or 2nd floor.
- P lives immediately below U, placing P on either 9th or 1st floor accordingly.
- Five persons between P and Q. If P is on 9th, then Q is on the 3rd floor; if P is on 1st, Q would be on the 7th.
- V lives on an even floor immediately above R.
- W lives on a floor below R, but not immediately below and on an even-numbered floor above Q's floor.
- Y lives above T’s floor and below S's floor, with S not on an even floor.
- Placing all correctly, S ends up on the 9th floor, Y on the 7th or 8th floor.
- There are 2 persons between Y and S. Thus, the correct answer, based on the information, is Option 4: Two.
