    B Data given in statement I and II together is necessary to answer the question. Correct Answer Incorrect Answer
    C Data given neither in statement I alone nor in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D Data given in statement II alone is not sufficient to answer the question while the data given in statement I alone is sufficient to answer the question. Correct Answer Incorrect Answer
    E None of the above Correct Answer Incorrect Answer

    Solution

    From statement I alone, The one, who works in L lives two floors above Y. Only two persons live between Y and the one, who works in O. W, who works in N lives immediate above the one, who works in O. The one, who works in J lives below W. Z lives two floors below the one, who works in J. V lives above the one, who works in K. We get:

    So, from statement I alone, we cannot answer who works in M. So, data given in statement I alone is not sufficient to answer the question.

    From statement II alone, U lives on 3 rd floor. Only one person lives between U and X. The one, who works in N lives immediately above X. Only two persons live between the one, who works in J and the one, who works in N. Z lives two floors below the one, who works in J. V works in L. The one, who works in K lives below V. We get:

    Case 1: V and L live on 4 th floor.

    Case 2: V and L live on 2 nd floor.Image
    So, from statement II alone, we cannot answer who works in M. So, data given in statement II alone is not sufficient to answer the question. From statement I and II together, we get:

    So, from statement I and II together we cannot answer who works in M.
