    A Data given in both statements I and II together are not sufficient to answer the question. Correct Answer Incorrect Answer
    B Data given in either statement I or statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    C Data given in statement I alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D Data given in both statements I and II together are sufficient to answer the question. Correct Answer Incorrect Answer
    E Data given in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer

    Solution

    From statement I, V lives two floors above U. Q lives three floors above T, who lives immediately above R. As many floors are below R as above S. We get: So, from statement I alone, we get either W or P lives on 7th floor. So, statement I alone is not sufficient to answer the question. From statement II, Only two persons live between W and U. P lives below U. W lives above sixth floor. P lives two floors above R. We get: Case 1: Case 2: Case 3: So, from statement II alone, we get that it is not sufficient to answer the question. From Statement I and Statement II together, we get:   So, W lives on seventh floor. Therefore data given in both statement I and II together are sufficient to answer the question.
