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?
Answer
The correct answer is D: 13.85%. Let original price = ₹10 and expenditure = ₹10. New price = ₹13.
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%.
