Y lives above Z but not on an odd numbered floor. The number of floors above Y is the same as below S. U lives immediately above W. The number of floors between W and T is the same as between S and X. V lives below T.Solution
We have, Z lives three floors above X who lives on an odd numbered floor. From the above condition, there are three possibilities. 
Again we have, The number of floors above Y is the same as below S. From the above condition, case3a gets eliminated. 
Again we have, U lives immediately above W. The number of floors between W and T is the same as between S and X. V lives below T. From the above condition, case2 gets eliminated. case3 shows the final arrangement.
