    Question

    I:┬а x2┬а- 33x + 242 = 0 II:┬а

    y2┬а- 4y - 77 = 0 Direction: In each of the following question, two equations are given. You have to solve both the equations to find the relation between x and y.
    A If x < y Correct Answer Incorrect Answer
    B If x > y Correct Answer Incorrect Answer
    C If x тЙд y Correct Answer Incorrect Answer
    D If x тЙе y Correct Answer Incorrect Answer
    E If relationship between x and y cannot be determined Correct Answer Incorrect Answer

    Solution

    From I => x2┬а- 33x + 242 = 0 => x2┬а- 22x - 11x + 242 = 0 =>x(x тАУ 22) -11(x тАУ 22) = 0 => (x тАУ 11) (x тАУ 22) = 0 => x = 11, 22 From II => y2┬а- 4y - 77 = 0 => y2┬атАУ 11y + 7y - 77 = 0 =>y(y - 11) +7(y тАУ 11) = 0 => (y + 7) (y тАУ 11) = 0 => y = -7, 11 Hence, x тЙе y
