    Two numbers are less than a third number by 30% and 37%,

    respectively. By how much percent is the second number less than the first?
    A 7% Correct Answer Incorrect Answer
    B 10% Correct Answer Incorrect Answer
    C 4% Correct Answer Incorrect Answer
    D 3% Correct Answer Incorrect Answer

    Solution

    Let Third number = 100
    First number is 30% less than 100 ⇒ First number = 100 - 30 = 70

    Second number is 37% less than 100 ⇒ Second number = 100 - 37 = 63

    Required answer = (70 - 63)/70 x 100 = 10%
