The one, who likes pink, lives on the adjacent floor of C.Solution
We have, Only two persons live between the one who likes red and E, who lives above the third floor. D lives immediately below the one who likes red. From this condition, there are two possibilities
Again we have, The one who likes yellow lives two floors above D. A lives three floors above the one who likes pink. A doesnтАЩt like yellow.
Again we have, No one lives between the one who likes black and white. Only three persons live between B and the one who likes white. The one, who likes pink, lives on the adjacent floor of C. From the above condition, case 1 gets eliminated.
