On which floor does the person live who likes Apple?

The one who lives 7^th floor is immediate above the one, who lives immediate below the one who likes Orange. So the one who likes Orange lives on 7^th floor. E lives on one of the floors below B, but does not live on the lowermost floor. There are three persons between B and E. So here we get two cases one when B lives on 6^th floor and the other when B lives on 7^th floor. Case 1 :-   Only one person lives between B and the one who likes Black . The one who likes White lives on one of the even-numbered floors above the one who likes Black . Only two persons live between G and the One who likes Black . Here we get further two more cases so we hold this case and move further with the other one case. Case 2:- Only one person lives between B and the one who likes Black .The one who likes White lives on one of the even-numbered floors above the one who likes Black . Only two persons live between G and the One who likes Black . The one who likes Yellow lives immediately above G. A lives immediately above F and does not like Black. The one who likes Green lives on the odd-numbered floors below F. so only one place left for Green i.e. 1^st floor. And for A and F 6^th and 5^th floor respectively. D lives on one of the floor above C. so one place left for C is 1^st floor.   Now, The one who likes Watermelon lives immediate above the one who likes Red. Only one person lives between the one who likes Red and the one who likes Blue. D does not like Red. So, only one place left for Red i. e. 2^nd floor. The one who likes Mango lives immediate above the one who likes Papaya. The one who likes Papaya lives below the one who likes Apple. So, only one place left for Madona and Papaya i.e. 2^nd and 1^st floor respectively. While F does not like Grapes and Banana. So F likes Apple and A likes Grapes. Therefore, this is the final arrangement.
