Q1. Sixteen persons namely A, B, C, E, N, O, P, Q, R, S, T, U, V, W, X and Y live in a four-storey building with two separate flats, i.e. flat 1 and flat 2, such that the lowest floor is 1, the floor just above it is 2, and so on; the topmost floor is 4. Flat 2 is west of flat 1, while floor 2 flat 1 is just above floor 1 flat 1 and floor 2 flat 2 is just above floor 1 flat 2. There are eight married couples, and each married couple lives together on the same floor. The persons whose names start with a vowel are females and live on an even-numbered floor. Not necessarily in the same order. A lives just above the flat of P's spouse. A's spouse lives in an odd-numbered flat. O and Q live on the same floor. T lives to the northeast of U and lives below E. Q does not live in the same flat as E. B, who lives on an even-numbered floor, lives two floors above N. S lives to the southwest of B but does not live below N. R lives to the north of X. R is not married to A. X's spouse lives to the east of Y. C is neither the spouse of Y nor X. V and U live in the same flat and both have the same gender. W's gender is the same as O's gender. How many floors are below the wife of O?
- same as floors above A
- same as floors below T
- same as floors between P and X
- more than two
Answer: same as floors between P and X
This is a complex floor-and-flat arrangement with couple and direction constraints. After placing the persons consistently, the wife of O is found on a floor such that the number of floors below her matches the number of floors between P and X. Therefore, the correct option is the one stating that relation.
