Question
Which of the following pair lives on perfect
cube-numbered floors? Study the following information carefully and answer the questions given below. Nine persons – A, B, C, D, E, F, G, H and I – are living on the same building such as ground floor is numbered as 1, just above it is floor 2, then the top floor is numbered as 9 but not necessarily in the same order. The following information is known about them. Only two persons live between C’s floor and B’s floor. Neither C nor H lives on an odd-numbered floor. The person who lives immediately above B lives three floors above F. There is only one floor between H’s floor and D’s floor. The number of floors above D is the same as the number of floors below G. At least one person lives between B and H. The number of floors between G and F is the same as the number of floors between E and D. A lives below I but above ESolution
 Only two persons live between C’s floor and B’s floor. Neither C nor H lives on an odd-numbered floor. The person who lives immediately above B lives three floors above F. The number of floors between G and F is the same as the number of floors between E and D. A lives below I but above E. This eliminates case 4.
