Question

    The product of two positive numbers is 500. If one of the

    numbers is seven times the other, then find the difference between the given two numbers.
    A 50.7 Correct Answer Incorrect Answer
    B 25.1 Correct Answer Incorrect Answer
    C 16.1 Correct Answer Incorrect Answer
    D 29.8 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let us assume one of the numbers is 'x'

    Then, another number is = 7 × x = '7x'

    So, x × 7x = 500

    Or, 7x² = 500

    Or, x² = 71.43

    Or, x = 8.45 {Since the numbers are positive}

    Required difference = {7 × (8.45) - 8.45} = (59.15 - 8.45) = 50.7
