    Question

    The price of wheat has increased by 45%. Mohit has

    decided to spend only 16% more than what he initially did on buying wheat. What is the percentage decrease in Mohit'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 Mohit be Rs. 100 per unit and Mohit's consumption be 10 units.   ∴ Initial amount spent = 100 × 10 = Rs. 1,000   New price of wheat = 145% of 100 = Rs. 145 and new total amount spent = 116% of 1000 = Rs. 1,160   ∴   New consumption = 1160/145 = 8 units   ∴  Decrease in consumption = 10 - 8 = 2 unit   ∴ % decrease = 2/10 × 100 = 20%
