    Question

    In each question two equations numbered (I) and (II) are given. You should solve both the equations and mark appropriate answer.

    I. 2x2 – 5x - 12 = 0 II.

    y2 – 11y + 30 = 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 relation between x and y cannot be established Correct Answer Incorrect Answer

    Solution

    I. 2x2 – 5x - 12 = 0 => 2x2 – 8x + 3x - 12 = 0 => 2x (x – 4) + 3 (x – 4) = 0 => x = -3/2, 4 II. y2 – 11y + 30 = 0 => y2 – 6y – 5y + 30 = 0 => y (y – 6) – 5(y – 6) = 0 => y = 6, 5 Hence, x < y
