    The price of wheat has increased by 65%. Rohit has

    decided to spend only 32% more than what he initially did on buying wheat. What is the percentage decrease in Rohit's wheat consumption?
    A 20% Correct Answer Incorrect Answer
    B 32% Correct Answer Incorrect Answer
    C 28% Correct Answer Incorrect Answer
    D 10% Correct Answer Incorrect Answer

    Solution

    Let the initial price of Rohit be Rs. 100 per unit and Rohit's consumption be 10 units.   ∴ Initial amount spent = 100 × 10 = Rs. 1,000   New price of wheat = 165% of 100 = Rs. 165 and new total amount spent = 132% of 1000 = Rs. 1,320   ∴   New consumption = 1320/165 = 8 units   ∴  Decrease in consumption = 10 - 8 = 2 unit   ∴ % decrease = 2/10 × 100 = 20%
