    Question

    I. 8y2 - 2y - 21 = 0 II.

    2x2 + x - 6 = 0 In the following questions, two equations numbered I and II are given. You have to solve both questions and give answer among the following options.
    A if x > y Correct Answer Incorrect Answer
    B if x тЙе y Correct Answer Incorrect Answer
    C if x < y Correct Answer Incorrect Answer
    D if x тЙд y Correct Answer Incorrect Answer
    E x = y or the relationship cannot be established between x and y Correct Answer Incorrect Answer

    Solution

    I. 8y2 - 2y - 21 = 0 8y2 +12y - 14y - 21 = 0 4y (2y + 3) - 7(2y +3) = 0 (4y - 7) (2y + 3) = 0 y = 7/4, - 3/2 II. 2x2 + x - 6 = 0 2x2 -3x + 4x - 6 = 0 x (2x - 3) + 2(2x - 3) = 0 (x + 2) (2x - 3) = 0 x = -2, 3/2 Hence, relationship cannot be established between x and y.
