Directions: Study the following information carefully and answer the questions given below:

Eight persons A, C, D, F, G, H, J, and K live (but not necessarily in the given order) in a 56-floor building but only on the floors which are multiple of 7. (For example - 7, 14, 21, and so on). Floors are arranged from bottom to top in increasing order. 

The number of persons living between D and H is equal to K and J. G lives on the floor which is a multiple of 3. The sum of floors of J and H is equal to the floor of F. D lives on the floor which is a perfect square. The difference between the number of floors between A and C is divisible by the floor number of C. The number of floor on which J lives is one-fourth of the total floors in the building.
