    Ten persons sit in two parallel rows i.e., row I and row

    II. Five persons P, Q, R, S and T sit in row I. Five persons U, V, W, X and Y sit in row II. The person in row I face towards the south and the persons in row II face towards the north. The person of row I face the person of row II. Row I is to the north of row II. The distance between any two adjacent persons in the row is same. Who faces Q? Statement I: T sits second to the right of the one, who faces V. Only two persons sit between V and W. Only one person sits between the one, who faces W and S.Statement II: R sits 3rd to the left of the person, who faces U. U sits immediate left of Y. The one, who faces Y sits second to the left of Q. P sits second to the left of the one, who faces the one, who sits immediate right of W. V faces the one, who sits adjacent to S. 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.
    A Data given in statement I alone is not sufficient to answer the question while the data given in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    B Data given in statement I and II together is necessary to answer the question. Correct Answer Incorrect Answer
    C Data given in statements I and II together is not 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, T sits second to the right of the one, who faces V. Only two persons sit between V and W. Only one person sits between the one, who faces W and S. We get:

    Case 1: Image

    Case 2: Image

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

    From statement II alone, R sits 3rd to the left of the person, who faces U. U sits immediate left of Y. The one, who faces Y sits second to the left of Q. P sits second to the left of the one, who faces the one, who sits immediate right of W. V faces the one, who sits adjacent to S. We get: Image

    So, from statement II alone, we get Q faces W. Therefore, data given in statement II alone is sufficient to answer the question.
