    Question

    In each question two equations are provided. On the basis of these you have to find out the relation between p and q. Give answer.

    I. p2 - 19p + 88 = 0    II.

    q2 - 48q + 576 = 0
    A if p = q Correct Answer Incorrect Answer
    B if p > q Correct Answer Incorrect Answer
    C if q > p Correct Answer Incorrect Answer
    D if p ≥ q Correct Answer Incorrect Answer
    E if q ≥ p Correct Answer Incorrect Answer

    Solution

    I. p2 - 19p + 88 = 0   (p - 11) (p - 8) = 0  p = 11 or 8   II. q2 - 48q + 576 = 0   (q – 24) (q – 24) = 0   q = 24 or 24    Hence,  q > p   Alternate Method:   if signs of quadratic equation is -ve and +ve respectively then the roots of equation will be +ve and +ve. So, roots of first equation = p = 11, 8 So, roots of second equation = q = 24 After comparing roots of quadratic eqution we can conclude that p < q.
