How many people live between the floors on which S and X

Solution

From the conditions, W likes Papaya and lives on floor number 8. Only five people live above the floors on which P lives. Only one person lives between P and the one who likes Grapes, it means the one who likes Grapes lives on either 2nd floor or 6th floor. Only three people live between the ones who like Grapes and Apple fruit. U lives immediately below the one who likes Mango. The one, who likes Mango lives on an even numbered floor, so only one place is left for the one who likes Mango now it is clear that P likes Mango. X likes Kiwi and lives immediately above W now it is clear that X lives on topmost floor.          Only two people live between Q and the one who likes Guava. The one, who likes Guava lives below the floor on which Q lives. So there is only one possibility that Q will live on 6th floor. Case-1 Case-2 T lives immediately above R. T does not like Apple, From this condition case-2 will be eliminated. Because in case-2 there is no places for T and R. Only case-1 will be continued with the remaining conditions. With the rest conditions, the one who likes Banana does not live immediately above or immediately below Q it means R likes Banana. S does not live immediately above or immediately below P so S will live on 7th floor. V does not like Watermelon so S will like Watermelon. It will be fixed that V lives on 5th floor and likes Orange. We will get final answer.
