    E None of these Correct Answer Incorrect Answer

    Solution

    From (i), it is clear that both Q and U are on even numbered floor and since, U is on 2ndfloor, only 4th,6th and 8th floor are there for Q and Y. Since, Y is not above Q, there are two possibilities: Possibility (a) – Q at 8thand Y at 6thfloor. Possibility (b) – Q at 6thand Y at 4thfloor. But statement (ii) says, that one who likes white lives on 4thfloor and Y does not like white, possibility (b) is not possible. Hence, we will go with possibility (a) which is Q at 8th(likes Violet) and Y at 6thfloor. Statement (ii) also says that person on 3rd floors likes Yellow. From (iii), it is clear that the person who likes pink is on the 5thfloor. From (vii), we can say that the person who likes red is on the 9thfloor and also the person who likes purple lives on the 6thfloor . From (v), T is not on the 1stfloor and also since he does not like Yellow, he is not on the 3rdfloor. From (iv), neither W nor R can be at the 9thfloor, as W likes green and R is not at the topmost floor. Also as W likes green, only two floors .i.e 7thand 1st, are left for W. Hence, there are two possibilities for W and R : Possibility (a) – W at 7thfloor and R at 3rdfloor. Possibility (b) - R at 5thfloor and W at 1stfloor. But we can see in the above table that T cannot be at 1stor 3rdfloor. Now (vi), says that there is one floor between the floor on which T and R live. Hence, R also cannot be at 3rdfloor. Therefore, possibility (a) cannot be correct. Hence, we will go ahead with the possibility (b) which is R at 5thand W at 1stfloor and also from (vi), it is clear that T will be on the 7thfloor. Only colourBlack is left for T, hence T likes Black. From (vi), it is also clear that V and P will be on 4thand 3rdfloors respectively. Now only person left for 9thfloor is X. Final arrangement will be as follows:
