    Question

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

    I. x2 – 26x + 168 = 0    

    II. 2y2 - 19y – 60 = 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 Relation cannot be established Correct Answer Incorrect Answer

    Solution

    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 = x = -16/3, 1 if signs of quadratic equation is -ve and -ve respectively then the roots of equation will be +ve and -ve. So, roots of second equation = y = 12, -5/2 After comparing roots of quadratice eqution we can conclude that x ≥ y.
