    Question

    In the given questions, you will find two equations labeled as I and II. solve both equations and determine the accurate relationship between the variables 'p' and 'q'. Choose the correct option based on your analysis of the solutions.

    I. 2p2 + 25p – 13 = 0 II.

    2q2 – 19q = 2q + 23
    A p > q Correct Answer Incorrect Answer
    B p < q Correct Answer Incorrect Answer
    C p ≥ q Correct Answer Incorrect Answer
    D p = q or the relationship cannot be established Correct Answer Incorrect Answer
    E p ≤ q Correct Answer Incorrect Answer

    Solution

    ATQ, From I: 2p2 + 25p – 13 = 0 Or, 2p2 + 26p – p – 13 = 0 Or, 2p(p + 13) – 1(p + 13) = 0 Or, (2p – 1)(p + 13) = 0 Or, p = (1/2), -13 From II: 2q2 – 19q = 2q + 23 Or, 2q2 – 19q – 2q – 23 = 0 Or, 2q2 – 21q – 23 = 0 Or, 2q2 – 23q + 2q – 23 = 0 Or, q(2q – 23) +1(2q – 23) = 0 Or, (2q – 23)(q + 1) = 0 Or, q = (23/2) or -1 So, no relation can be established between ‘p’ and ‘q’
