Study the following information carefully and answer the questions given below :
Nine friends — A, B, C, D, E, F, G, H and I — live on nine different floors of a building but not necessarily in the same order. The lower most floor of the building is numbered one, the one above that is numbered two and so on till the topmost floor is numbered nine. I lives on floor numbered six. E lives on an odd numbered floor above I. Only three people live between E and G. A lives on an even numbered floor immediately below D but not on the floor numbered eight. Only one person lives between A and F. C lives on one of the floors below F. The number of people living above C is equal to the number of people living below H.
In which of the given pairs of people, is even number of people living between them?
I lives on floor numbered six and E lives on an odd numbered floor above I, => let E lives on 7th floor.
Only three people live between E and G, => G lives on 3rd floor
A lives on an even numbered floor immediately below D but not on the floor numbered eight, => A lives on 4th floor and D lives on 5th floor.
Only one person lives between A and F and C lives on one of the floors below F, => F lives on 2nd floor which means C lives on 1st floor.
Since, 8 people live above C, => 8 people should live below H, => H lives on 9th floor.
The only remaining floor, i.e. 7th floor is taken by B. The arrangement :
Number of persons living between :
G & C = 1
H & E = 1
E & D = 1
B & I = 1
I & H = 2 (even)
=> Ans - (E)
