Solution

By using the given conditions, B lives in an even numbered floor but above 4th floor. From this there can be two possible cases. Case-1: B lives on 6th floor and Case-2: B lives on 8^th floor. L likes Fossil and lives on an odd numbered floor. L doesn’t live at the lowermost floor and at the floor just below or above B. In case-1, L lives on 3rd floor and in case-2, L lives either on 5th floor or on 3rd floor.  Four people lives between the one who likes Fossil and the one who likes Titan. From this it is clear that L lives on 3rd floor. The one who likes Citizen lives immediate below the floor on which the one who likes Titan lives. Two people live between A and the one who likes Citizen.    A doesn’t like Casio and Fastrack. From this case-2 will be eliminated. Further J likes Omega and lives at one of the floor above C. So, J can live on 5th floor only. M likes Tommy. So, M lives on ground floor and C lives on 2nd floor. The person who likes Fastrack and TIMEX doesn’t live at the lowermost floor. So, B likes Fastrack. N does not like Citizen. So, A likes TIMEX and K lives on 7th floor. So, the final arrangement is----
