Who lives in Flat-A of 3rd

Solution

1. E lives in the west of C on an odd numbered floor. 2. J, who lives in the same type of flat as that of E, lives either three floors below or above A in the same type of flat as that of A. It implies that E, J, A live in flat-A of their floors while B, C live in flat-B of their floors. 3. F lives two floors above G such that they both live in either Flat-A or Flat-B of their floors. The next point is that J and A have two floors in between them and E lives on an odd numbered floor. So, if we start placing E, J, A, we can never place F and G who are two floors apart from each other in flat-A of their floors. So, it clearly means that F, G live in Flat-B. Thus, we finally get two cases: Case 1: J, A live on 5, 2 floors in any order. And I lives on 2nd floor. 4. H lives neither on the topmost floor nor to the east of A. Inference: So, D lives in flat-A on 5th floor and we get the floors of A and J. The final arrangement is shown below:
