Question
Who among the following lives immediate above the vacant
flat? Study the following information carefully to answer the given questions: There are eight persons i.e. D, E, F, G, H, I, J and K who lives in a building having three floors such that ground floor is numbered as 1 and above it is 2 and so on up to top floor numbered as 3. Each of the floor consist of 3 flats as flat-1, flat-2 and flat-3. Flat-1 of floor-2 is immediately above flat-1 of floor-1 and immediately below flat-1 of floor-3 and in the same way flat-2 of floor-2 is immediately above flat-2 of floor-1 and immediately below flat-2 of floor-3 and so on. Flat-2 is in east of flat-1 and flat-3 is in east of flat-2. One of the flats is Vacant. Note: If A lives above (or below) B, then they are living in same flat unless stated otherwise. I lives to the immediate west of H on floor-2. G lives in the same flat in which I lives. E who lives in an odd numbered flat, does not live above K. Immediate west flat of E is vacant. F and G live in the same floor while F and J shared the same flat. D lives in an even numbered floor. K and E do not share the same floor.Solution
I lives to the immediate west of H on floor-2. D lives in an even numbered floor. As per these lines two cases will arrive: 
G lives in the same flat in which I lives. (By using this line we get 2 more cases) 
E who lives in an odd numbered flat, does not live above K. Immediate west flat of E is vacant. Also K and E do not share the same floor. Brief Hints: E must live in FLAT-3 of floor-1 (odd number) and lives below K. 
Note: Immediate west flat of E is vacant (this condition not possible in Case-2A, hence rejected) 
F and G live in the same floor while F and J shared the same flat. Note: Case-1 and Case-1-A gets rejected since we can’t satisfy the above said condition 
Case 2 is the final result. [Final Arrangement]
