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

    I. x2 = 100 II. y2 - 9y +

    20 = 0
    A if x = y or relation cannot be established between x and 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

    Solution

    I. x2 = 100 x= +10. -10 II. y2 - 9y + 20 = 0 y2 - 5y - 4y + 20 = 0 y (y - 5) - 4 (y - 5 ) = 0 ( y - 4 ) ( y - 5 ) = 0 y = 4, 5 Hence, if x = y or relation cannot be established between x and y
