    Question

    In the question, two equations I and II are given. You

    have to solve both the equations to establish the correct relation between x and y and choose the correct option. I. x³ = -1331 II. y² + 23y + 132 = 0
    A x > y Correct Answer Incorrect Answer
    B x < y Correct Answer Incorrect Answer
    C x ≥ y Correct Answer Incorrect Answer
    D x ≤ y Correct Answer Incorrect Answer
    E x = y or the relationship cannot be established Correct Answer Incorrect Answer

    Solution

    ATQ,

    From I:

    x³ = -1331

    x = -11

    From II:

    y² + 23 + 132 = 0

    y² + 11y + 12y + 132 = 0

    y(y + 11) + 12(y + 11) = 0

    (y + 11)(y + 12) = 0

    y = -11, -12

    So, x ≥ y
