    Question

    The product of two positive numbers is 192. If one of

    the numbers is twice the other, then find the difference between the given two numbers.
    A 3.1 Correct Answer Incorrect Answer
    B 5.1 Correct Answer Incorrect Answer
    C 6.1 Correct Answer Incorrect Answer
    D 9.8 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let us assume one of the numbers is 'x'

    Then, another number is = 2 × x = '2x'

    So, x × 2x = 192

    Or, 2x² = 192

    Or, x² = 96

    Or, x = 9.8 {Since the numbers are positive}

    Required difference = {2 × (9.8) - 9.8} = (19.6 - 9.8) = 9.8
