D? Answer the questions based on the information given below. Eight persons viz. A, B, C, D, E, F, G and H 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. E lives on an odd-numbered floor and three floors below F. G lives between E and F. Only two persons live between G and H who doesn’t live on the bottommost floor. D lives on an even-numbered floor. The number of floors above D is the same as the number of floors below A. C lives three floors below B.Solution
