When the price of sugar gets raised by 30%, a person increases his expenditure on sugar only by 12%. By what percentage (correct up to two decimal places) should he reduce his consumption of sugar so as to be able to maintain the same level of expenditure?
A.11.54%
B.12.75%
C.15.75%
D.13.85%✓ Correct
Explanation
Let original price = ₹10 and expenditure = ₹10. New price = ₹13. New expenditure = ₹11.2. Reduction in consumption = (13−11.2)/13 × 100 = 1.8/13 × 100 ≈ 13.85%.
