    Question

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

    I. 3x² - 22x + 40 = 0 II. 2y² - 19y +

    44 = 0
    A if x > y Correct Answer Incorrect Answer
    B if x < y Correct Answer Incorrect Answer
    C if x ≥ y Correct Answer Incorrect Answer
    D if x ≤ y Correct Answer Incorrect Answer
    E if x=y or the relationship cannot be established. Correct Answer Incorrect Answer

    Solution

    I. 3x² - 22x + 40 = 0 Pairs are: -12, -10 So by changing its signs & dividing by a i.e.3, we will get x = 4, 10/3 II. 2y² - 19y + 44 = 0 Pairs are: -11, -8 So by changing its signs & dividing by a i.e.2, we will get y = 11/2, 4 Hence, x ≤ y.
