Question
Which of the following given pair is different from
rest? Answer the following questions according to the given statements: There are eight persons P, Q, R, S, T, U, V, and W, who live on four different floors among floor 1, floor 2, floor 3 and floor 4. Each floor has two different flats viz. flat 1 and flat 2. There are 2 flats on each floor flat 1 – flat 2 from left to right in such a way that flat 1 of the fourth floor is exactly above flat 1 of the third floor and flat 1 of the third floor is exactly above flat 1 of the second floor and other flats are situated in the same way. R lives one floor above the floor on which Q lives. U lives with Q who lives two floors below S. Q lives on the second floor. T lives in flat 2 of the first floor. V lives on the third floor but not in flat 1. W does not live on the fourth floor but in flat 1. Q lives in even numbered flat. P and R live in flat 1 but on different floors.Solution
Q lives on the second floor. Â Case I U lives with Q who lives two floors below S. R lives one floor above the floor on which Q lives. Case I
