    more marbles than ‘O’. By how much percent is the number of marbles with ‘M’ less than that with ‘O’?
    A 42% Correct Answer Incorrect Answer
    B 60% Correct Answer Incorrect Answer
    C 34% Correct Answer Incorrect Answer
    D 9% Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let number of marbles with ‘N’ be ‘20x’.

    Number of marbles with ‘M’ = 0.65 × 20x = ‘13x’

    Number of marbles with ‘O’ = (20x / 1.4) = ‘14.29x’

    Required percentage = {(14.29x – 13x)/14.29x} × 100 ≈ 9.03% or 9%
