Question

    The question given below consists of two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the statements and answer the question.

    Seven persons D, E, F, G, H, I and J sit in a linear

    row and face towards north direction. Who sits second to the right of J? Statement I: F sits second from an extreme end. Only three persons sit between F and E. H sits adjacent to E. G sit third to the left of H. J doesn't sit adjacent to G. Statement II: E sits fourth to the right of F. Neither E nor F sits at an extreme end. D sits second to the left of I. G sits to the left of H and to the right of J.
    A Data given in statement I and II together are not sufficient to answer the question. Correct Answer Incorrect Answer
    B Data given in both statement I and II together are necessary to answer the question. Correct Answer Incorrect Answer
    C Data given in statement I alone is sufficient to answer the question but data given in statement II alone is not sufficient to answer the question. Correct Answer Incorrect Answer
    D Data given in statement II alone is sufficient to answer the question but data given in statement I alone is not sufficient to answer the question. Correct Answer Incorrect Answer
    E None of the above Correct Answer Incorrect Answer

    Solution

    From statement I, F sits second from an extreme end. Only three persons sit between F and E. H sits adjacent to E. G sit third to the left of H. J doesn't sit adjacent to G. We get: J          F          D/I       G         I/D       E         H From statement I alone, we get either D or I sits second to the right of J. From statement II, E sits fourth to the right of F. Neither E nor F sits at an extreme end. D sits second to the left of I. G sits to the left of H and to the right of J. We get: Case 1: J          F          D         G         I           E         H Case 2: J          F          G         H         D         E         I Case 3: D         F          I           J          G         E         H   From statement II alone, we get one of the persons among D, G or E sits second to the right of J. Combining statement I and II together, we get: J          F          D         G         I           E         H So, from statement I and II together, we get D sits second to the right of J. Therefore, data given in both statement I and II together are necessary to answer the question.
