F is 31 years old and B is 26 years old. H is elder to F so H is either 34 or 38 years old. D is 5 years elder to G so only two combinations have 24-29 and 29-34. One person lives between G and the one who is 24 years old so G cannot be 24 years old then G is 29 years old and D is 34 years old. Now H is 38 years old. The difference of age between A and C is same as difference between D and H so 4 years is difference between D and H now A or C age is 20 or 24 years old. Now we can see that E is 27 years old.

F lives three floors above the one who is 27 years old. C lives just above F. C lives on an odd numbered floor so C either lives on 7th or 5th floor.

If C lives on 7th floor then the one who is 27 years old i.e. E lives on 3rd floor. The one who is 34 years old is living on top floor so D lives on 8th floor. The number of floors above D is same as below E then E must live on 1st floor but E lives on 3rd floor so that case gets rejected.

If C lives on 5th floor,then E lives on 1st and F lives on 4th floor and D lives on 8th floor. Difference of age between A and B is at least 3 years so A is 20 years old and C is 24 years old. One person lives between G and the one who is 24 years old so either G lives on 7th or 3rd floor. The number of floors between G and C is same as A and E now G must live on 7th and A lives on 3rd floor. B lives just above the one who is 24 years old. So B lives on 6th and H lives on 2nd floor.
