    Question

    In the following questions two equations numbered I and II are given. You have to solve both the equations. Give answer :

    I. 104x² + 9x - 35 = 0 II. 72y² - 85y +

    25 = 0
    A If x < y Correct Answer Incorrect Answer
    B If x > y Correct Answer Incorrect Answer
    C If x = y or no relationship cannot be established between x and y Correct Answer Incorrect Answer
    D If x ≥ y Correct Answer Incorrect Answer

    Solution

    I. 104x² + 9x - 35 = 0 104x² + 65x - 56x - 35 = 0 13x (8x + 5) – 7(8 x + 5) = 0 (13 x - 7) (8x + 5) = 0 ∴ x = 7/13 , - 5/8 II. 72y² - 85y + 25 = 0 72y² - 40 y - 45y + 25 = 0 8y(9 y – 5) - 5 (9 y – 5) = 0 (8 y - 5)(9 y – 5) = 0 ∴ y = 5/8 , 5/9 Hence, x < y
