(i) D lives North West of E’s flat. (ii) E does not live on second floor. (iii) G does not live in the same flat number in which E lives. G lives above E. From these statements, we will have six cases: D lives at flat 1 either on floor no. 4 or 3 or 2. E lives at flat 2 on floor no. 1. G lives at flat 1 on floor no. 4 or 3 or 2. (iv) B lives east of H who lives south of D. H lives at flat 1 of either floor no. 2 or 3. B lives at flat 2 of either floor no. 2 or 3. Case 4 , 5 and 6 will get discarded. 
(vi) C lives one of the floor below D’s floor. So, C lives at flat 2 of floor no. 2. (vii) A likes Audi and lives in even number flat. So, A lives at flat 2 of floor no. 4. (viii) Only one floor gap between the one who likes Renault and the one who likes Toyota. The one who likes Honda does not live in even number flat. (ix) The one who likes Ferrari lives west of the one who likes Ford. The one who likes Toyota lives above the floor of one who likes Ferrari. The one who likes BMW lives in even number flat. The one who likes Toyota lives at flat 1 on floor no. 4 and the one who likes Ferrari lives at flat 1 on floor no. 3. The one who likes Honda lives at flat 1 on floor no. 2.
