On which floor does the person live who likes Mahindra?

Solution

Explanation:- The one who lives 7^th floor is immediate above the one, who lives immediate below the one who likes Ford. So the one who likes Ford lives on 7^th floor. ADITIYA lives on one of the floors below ANKIT, but does not live on the lowermost floor. There are three persons between ANKIT and ADITIYA. So here we get two cases one when ANKIT lives on 6^th floor and the other when ANKIT lives on 7^th floor. Case 1 :-                                                                                                                                                                                                                            Only one person lives between ANKIT and the one who likes Samsung . The one who likes DELL lives on one of the even-numbered floors above the one who likes Samsung .Only two persons live between ANIKET and the One who likes Samsung . 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 ANKIT and the one who likes Samsung .The one who likes DELL lives on one of the even-numbered floors above the one who likes Samsung . Only two persons live between ANIKET and the One who likes Samsung . The one who likes Toshiba lives immediately above ANIKET. AMAN lives immediately above ARJUN and does not like Samsung. The one who likes Lenovo lives on the odd-numbered floors below ARJUN. so only one place left for Lenovo i.e. 1^st floor. And for AMAN and ARJUN 6^th and 5^th floor respectively.  ABHISHEK lives on one of the floor above AJAY. so one place left for AJAY is 1^st floor. Now, The one who likes Volvo lives immediate above the one who likes ACER. Only one person lives between the one who likes ACER and the one who likes ASUS. ABHISHEK does not like ACER. So, only one place left for ACER i.e. 2^nd floor.  The one who likes Verna lives immediate above the one who likes Hyundai. The one who likes Hyundai lives below the one who likes Mahindra. So, only one place left for Verna  and Hyundai i.e 2^nd and 1^st floor respectively. While ARJUN does not like BMW and Maruti. So ARJUN likes Mahindra and AMAN likes BMW. Therefore, this is the final arrangement.
