Study the following data carefully and answer the questions accordingly. W, X, Y, T, U, V and Z are seven colleagues, who live in a seven-storey building. The ground floor is numbered 1; the floor above it is numbered 2; and so on, until the topmost floor is numbered 7.
Each of them works in different companies i.e. IOC, RIL, BPCL, SBI, Tata Motors, ONGC and HPCL but not necessarily in the same order. Z and X don’t work in SBI. The one, who works in Tata motors, lives just above X. The one, who works in HPCL, lives above T. Z lives on the fifth floor. Neither X nor Z works in RIL. There are two floors between the floors on which X and V lives. The one, who works in ONGC, lives on the topmost floor. V lives on an evennumbered floor. Y works in BPCL. There is only one floor between U and the one, who works in RIL. There are three floors between T and the one, who works in IOC.
