Question
How many persons live between A and W?
Answer the questions based on the information given below. Eight persons viz. U, V, W, X, Y, Z, A and B are living in an eight-storey building, but not necessarily in the same order. The bottommost floor is numbered as 1 and the floor immediately above it is numbered as 2 and so on. Not more than one person lives on the same floor. The consecutive alphabetically named person doesn’t live on the adjacent floors of the building. Y lives on an odd-numbered floor and three floors below Z. A lives between Y and Z. Only two persons live between A and B who doesn’t live on the bottommost floor. X lives on an even-numbered floor. The number of floors above X is the same as the number of floors below U. W lives three floors below V.Solution
Y lives on an odd-numbered floor and three floors below Z. A lives between Y and Z. Only two persons live between A and B who doesn’t live on the bottommost floor. 
X lives on an even-numbered floor. The number of floors above X is the same as the number of floors below U. W lives three floors below V. The consecutive alphabetically named person doesn’t live on the adjacent floors of the building. Hence, cases 1 and 3 get eliminated.
