    Question

    If the price of a wheat bag is reduced by 25%, by what

    percentage should a family increase its consumption of wheat bags to ensure that their total expenditure on wheat remains unchanged?
    A 20.20% Correct Answer Incorrect Answer
    B 33.33% Correct Answer Incorrect Answer
    C 66.67% Correct Answer Incorrect Answer
    D 65.55% Correct Answer Incorrect Answer

    Solution

    ATQ;
    Let initial price of wheat bag be Rs. 100 per kg and initial consumption be 1 kg
    So, initial total expenditure = Rs. 100
    Reduced price of wheat bag = {100 – (25% of 100)} = Rs. 75
    So, new consumption = {100/75} = (4/3) kg
    Therefore, percentage increased = [{(4/3) – 1}/1] × 100 = 33.33%
