Question
S, T, U, V, W, X and Y live on seven 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 till the topmost floor is numbered 7. U lives on the fourth floor. Only two persons live between U and V. T lives immediately below V. W lives immediately above X but X does not live on the lowermost floor. S does not live on the lowermost floor. On which floor number does S live?

The correct answer is
Floor Number 5
To solve this problem, we need to deduce the floor each person lives on, based on the clues given:
- U lives on the fourth floor.
- There are only two persons between U and V.
- T lives immediately below V.
- W lives immediately above X, and X does not live on the lowermost floor.
- S does not live on the lowermost floor.
Let's tackle each point to plot the arrangement:
- Since U is on the 4th floor, V must be either on the 1st or 7th floor because there must be two floors between U and V.
- From point 3, T lives immediately below V.
- If V were on the 1st floor, T would have to be on the ground floor (floor 0), which doesn't exist. Therefore, V must be on the 7th floor, and T will be on the 6th floor.
- Now, considering point 4, W lives immediately above X. If we place W and X on floors 2 and 3 respectively, it works because X is not on the lowermost floor.
- Looking at point 5, S cannot be on floor 1. So, S must be placed on floor 5.
With this arrangement, the floors are organized as follows:
| Floor 7 | V |
| Floor 6 | T |
| Floor 5 | S |
| Floor 4 | U |
| Floor 3 | X |
| Floor 2 | W |
| Floor 1 | - |
Thus, S lives on Floor Number 5.
