Eight people P, Q, R, S, T, U, V and W live on an eight-floor building where the ground floor is numbered 1 and the topmost floor is numbered 8, one person per floor. Only two people live above S. Q lives immediately below S. Three people live between Q and R. P lives on an even-numbered floor somewhere above S. T lives immediately above R. U lives immediately above V. On which floor does W live?

Question

Accepted Answer

Floor 7. Only two above S puts S on 6; Q on 5. R is four apart from Q so R on 1, T on 2. The only even floor above 6 is 8, so P on 8. U above V fills the consecutive pair 3-4 (V=3, U=4), leaving 7 for W. Order: R1, T2, V3, U4, Q5, S6, W7, P8.
