    Solution

    From statement I, W is kept in a prime numbered box. V is kept three boxes above W. Z is kept one box above X. Y is kept one box below T. U is kept three boxes below T. We get: From statement I alone, we get T is the fourth box. From statement II, X is kept three boxes above Y. U is kept two boxes below Y. Z is kept above X. V is kept above T. W is kept below T. We get: From statement II alone, we get T is the fourth box. Therefore, data given in either statement I or II alone is sufficient to answer the question.
