Question

    Study the following information carefully and answer the below questions. Eight persons- S, T, U, V, W, X, Y and Z are sitting on the rectangular table facing the centre but not necessarily in the same order. Three of them sit at each long side where one person sits at each smaller side. The consecutive alphabetically named persons are not sitting together. The number of persons sits between X and W is the same as the number of persons sit between W and S. Z sits second to the right of X who sits on the smaller side of the table.  The number of persons sits between U and S is one more than the number of persons sit between V and X when counted from the right of both U and V. W sits second to the right of T. Only two persons sit between Z and V.

    If all the persons are arranged in alphabetical order

    from I in a clockwise direction, then how many persons remain unchanged in their position(Excluding I)?
    A None Correct Answer Incorrect Answer
    B Four Correct Answer Incorrect Answer
    C Three Correct Answer Incorrect Answer
    D Two Correct Answer Incorrect Answer
    E One Correct Answer Incorrect Answer

    Solution

    We have, Z sits second to the right of X who sits on the smaller side of the table. Only two persons sit between Z and V. From the above condition, there are two possibilities. Case-1 Again we have, W sits second to the right of T. From the above condition, there are three possibilities. Case-2 Again we have, The number of persons sits between X and W is the same as the number of persons sit between W and S. The number of persons sits between U and S is one more than the number of persons sit between V and X when counted from the right of both U and V. From the above condition, case1 and case2 get eliminated. Case2a shows the final arrangement.
