S, T, U, V, W, and X live on six different floors of the same building. The lowermost floor in the building is numbered 1, the floor above it is numbered 2, and so on until the topmost floor is numbered 6. V lives on the lowermost floor. X and U each live on an even-numbered floor. T lives exactly between U and W. W lives on floor number 2. Who lives on floor number 5?

Explanation

Given Information: V lives on the lowermost floor, which is floor number 1. So, VVV is on floor 1. X and U each live on an even-numbered floor. This means that XXX and UUU could be on floors 2, 4, or 6. T lives exactly between U and W. This implies that TTT is on a floor that is exactly between the floors of UUU and WWW. W lives on floor number 2. So, WWW is on floor 2. Step-by-Step Deduction: Since VVV is on floor 1 and WWW is on floor 2, we have: Floor 1: VVV Floor 2: WWW XXX and UUU must live on even-numbered floors. With floor 2 already occupied by WWW, XXX and UUU can only be on floors 4 or 6. TTT lives exactly between UUU and WWW. Since WWW is on floor 2, TTT must be on floor 3 (one floor above WWW), and UUU must be on floor 4. Floor 3: TTT Floor 4: UUU This leaves floor 5 and floor 6. Since XXX must live on an even-numbered floor, XXX must be on floor 6. Floor 6: XXX Finally, floor 5 is the only floor left, so SSS must live on floor 5. Floor Arrangement: Floor 1: VVV Floor 2: WWW Floor 3: TTT Floor 4: UUU Floor 5: SSS Floor 6: XXX Answer: The person who lives on floor number 5 is S.
