    Question

    The price of sugar has increased by 30%. Sachin has

    decided to spend only 17% more than what he initially did on buying sugar. What is the percentage decrease in Sachin's sugar 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 Sachin be Rs. 100 per unit and Sachin's consumption be 10 units.   ∴ Initial amount spent = 100 × 10 = Rs. 1,000   New price of sugar = 130% of 100 = Rs. 130 and new total amount spent = 117% of 1000 = Rs. 1,170   ∴   New consumption = 1170/130 = 9 units   ∴  Decrease in consumption = 10 - 9 = 1 unit   ∴ % decrease = 1/10 × 100 = 10%
