We have, Only two persons live between the one who likes grapes and E, who lives above the third floor. D lives immediately below the one who likes grapes. From this condition, there are two possibilities Again we have, The one who likes banana lives two floors above D.A lives three floors above the one who likes mango. A doesn’t like banana.
Again we have, No one lives between the one who likes papaya and watermelon. Only three persons live between B and the one who likes watermelon. The one, who likes mango, lives on the adjacent floor of C. From the above condition, case 1 gets eliminated. hence, case 2 shows the final arrangement.
