A lives in an even numbered flat on lowermost floor i.e. A lives on floor ground floor in flat 2. J lives in an even numbered flat on floor number 2. A and B live on same floor. D lives immediately above Name the numbers of their flats is same. So, Now, B either lives immediate west or east of A which means D either lives in flat 3 or flat 1. So, we have two possibilities. Case I: When B and D live on flat – 3: 
C lives somewhere above I in same flat number, but not on flat 3. Now, we cannot fix C and I in same flat number in case II, so, case II is invalid. The final arrangement is as follows:
