    Question

    In each of these questions two equations numbered I and II are given. You have to solve both the equations and give answer, if – 

    I.  p²= ∛1331

    II. 2q²  - 21q + 55 = 0

    A p = q or relationship between p and q can’t be established. Correct Answer Incorrect Answer
    B p > q Correct Answer Incorrect Answer
    C p < q Correct Answer Incorrect Answer
    D p ≥ q Correct Answer Incorrect Answer
    E p ≤ q Correct Answer Incorrect Answer

    Solution

    I.  p² = ∛1331 p = ±√11 = ±3.316 II. 2q²  - 21q + 55 = 0 2q² - 10q  - 11q + 55 = 0 2q(q - 5)  - 11( q - 5) = 0 (2q - 11) (q - 5) = 0 q = 5  ,11/2 Hence p < q,
