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.
