    more pens than ‘R’. By what percentage is the number of pens with ‘P’ less than that with ‘R’?
    A 12.5% Correct Answer Incorrect Answer
    B 20% Correct Answer Incorrect Answer
    C 35.1% Correct Answer Incorrect Answer
    D 28% Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the number of pens with ‘Q’ be ‘20x’.

    Number of pens with ‘P’ = 0.70 × 20x = ‘14x’

    Number of pens with ‘R’ = (20x / 1.25) = ‘16x’

    So, the required percentage = {(16x – 14x)/16x} × 100 = 12.5%
