1. M lives in flat 2 on odd numbered floor. 2. Q lives above M in the same type of flat and to the east of R. 3. R doesn’t live on floor 3. So, M lives on flat 2 of floor 3 or flat 2 of floor 1. Case U: M lives on flat 2 of floor 3: 
4. O and T live in the same type of flat such that O lives immediately above T but below floor 3. 5. O lives in southeast of R. 6. V lives to the west of O. V and S live in the same type of flat and V lives immediately above S, this is not possible in case II(b), so case II(b) is rejected. 7. S doesn’t live in flat 1, so case II(a) is rejected. So, V lives in flat 2 of floor 2 and S lives in flat 2 of floor 1. O and T lives in flat 3.
