Study the following information carefully and answer the questions given below:
Seven persons J, K, L, M, N, O and P live on seven different floors of a building but not necessarily in the same order. The lower most floor of the building is numbered 1, the one above that is numbered 2 and so on till the topmost floor is numbered 7. Each one of them also likes a different subject namely-English, History, Commerce, Biology, Accounts, Geography and Computer (but not necessarily in the same order.)
• J lives on an odd numbered floor but not on the floor numbered 3. The one who likes Accounts lives immediately above J. Only two persons live between M and the one who likes Accounts.
• The one who likes History lives on one of the odd numbered floors above M. Only three persons live between L and the one who likes History. The one who likes Commerce lives immediately above L.
• The one who likes English lives immediately above the one who likes Computer. P lives on an odd numbered floor.
• Only one person lives between K and N. K lives on one of the floors above N. Neither L nor J likes Biology. N does not like Commerce.
J lives on an odd numbered floor but not on the floor numbered 3 and the one who likes Accounts lives immediately above J, => J lives either on floor 1 or 5, let he lives on floor 5 (case 1). Thus, the one who likes Accounts lives on 6th floor.
Only two persons live between M and the one who likes Accounts, => M lives on 3rd floor
The one who likes History lives on one of the odd numbered floors above M, => He lives on 5th floor.
Only three persons live between L and the one who likes History, => L lives on 1st floor.
The one who likes Commerce lives immediately above L, => He lives on 2nd floor.
The one who likes English lives immediately above the one who likes Computer, => The one who likes English lives on 4th floor.
P lives on an odd numbered floor, => P lives on 7th floor.
Only one person lives between K and N and K lives on one of the floors above N. Also, N does not like Commerce, => K and N lives on 6th and 4th floors respectively.
Neither L nor J likes Biology, => P likes Biology.
Clearly, none of the options is true.
=> Ans - (C)
