Find the odd pair out:

1. J lives immediately above A, who doesn’t live on a prime numbered floor. 2. E lives to the south east of A.Z’s floor is immediately below E’s floor but they live in different types of flat. So, A and J live on floor 4 and floor 5 of D1, respectively. E lives on floor 2 or floor 3. 3. L and M live on same numbered floor. 4. X lives on floor 1 of one of the buildings, this is not possible in case II, so case II is rejected. 5. Y lives above K, who lives to the north east of L. So, L and M live on floor 3. Y lives on floor 5 of D2. F lives on floor 2 of D1. The final table is given below: Logic: Z and Y both live on odd floors.
