Question
How many persons live below D (in the same type of
flat)? Answer the questions based on the information given below. Ten persons (D, E, F, G, H, I, J, K, L and M) live on 10 different flats of a 5 storey building, where the bottommost floor is 1 and the floor above is 2 and so on. There are 2 types of flats on each floor, flat A and flat B such that flat A is in the west of flat B. Flat A of floor 1 is immediately below of flat A of floor 2, which is immediately below of flat A of floor 3 and so on, similarly for flat B. The dimensions of each of the flats are same. G lives three floors above K in the same type of flat. E lives south east of M. L lives somewhere to the south west of G. F lives to the north east of D. H lives immediately below L in the same type of flat but not to the south west of K. J lives two floors above M in the same type of flat.Solution
1. G lives three floors above K. G and K lives in same flat. 2. L lives somewhere to the south west of G. 3. H lives immediately below L but not to the south west of K.H and L lives in same flat. So, G lives in flat B. G lives on either floor 4 or floor 5. Case I: G lives on floor 4: 
4. J lives two floors above M. 5. E lives south east of M, this is not possible in case I(a) and case II, so case I(a), case II(a) and case II(b) are rejected. So, J lives on floor 5 of flat A. M lives on floor 3 of flat A. E lives on floor 2 of flat B 
7. F lives to the north east of D.M and J lives in same flat. So, D lives on floor 4 of flat A. F lives on floor 5 of flat B. I lives on floor 3 of flat B. The final table is given below:
