Four friends Sachin, Rachit, Raj and Pintu live on separate floors of a 4-floor building, but not necessarily in the same order. The ground floor is numbered 1, the first floor is numbered 2, and so on until the topmost floor is numbered 4. • Sachin does not live on an even-numbered floor. • Only three friends live below the floor on which Pintu lives. • Rachit lives immediately above Sachin. Which floor does Raj live on?
