Question
As many persons live between C and I is the same as the
number of person lives between G and ___? Study the following information carefully and answer the below questions. Nine persons- A, B, C, D, E, F, G, H, and I are living in nine-storey building such that the bottommost floor is numbered as one and immediately above it is numbered as two and so on till the topmost floor is numbered as nine. A lives four floors below C, either of them lives on the topmost floor or bottommost floor. Only two floors are there between A and B. The number of floors between C and B is the same as the number of floors between G and D. B lives immediately above D. E lives three floors above H who lives on an even number floor. The number of floors between H and D is the same as the number of floors between I and F. F and E does not live on the adjacent floors.Solution
We have, A lives four floors below C, either of them lives on the topmost floor or bottommost floor. Only two floors are there between A and B. From the above condition, there are three possibilities. 
Again we have, E lives three floors above H who lives on an even number floor. The number of floors between H and D is the same as the number of floors between I and F. F and E does not live on the adjacent floor. From the above condition, case-1 and case-2 get eliminated. Case-1a shows the final arrangement.
