The price of sugar increased by 22.5%. Anita wants to keep her expenditure on sugar same as before. By what percentage must she reduce her consumption of sugar (correct to two place of decimals)?

Correct option is B

Given:

Price of sugar increased by 22.5%

Solution:

Let the price of CNG be Rs100

Increased price = 100 + 22.5% of 100  = Rs. 122.5

Reduction on Rs. = 122.5 - 100 = Rs. 22.5​​

Reduction on Rs 100 = $$\frac{22.5}{122.5}\times 100 = 18.37\%$$
