Look at this answer Only the digit is changed otherwise the method of doing this question is same!
If the price of a commodity increases by R%, then the reduction in consumption so as not to increase the expenditure is Here R% = 25% Hence % decrease in the consumption of sugar

Let's say 1 kg of sugar is Rs. 100.
Therefore, an increase of 10% would be Rs. 110 (100 + 10).
Which implies that 1 kg of sugar is Rs. 110. Now, we need to find out how much sugar is available for Rs. 100 at the new prices.
The equation will be:
x = 100/110 = 0.91 kg (approx)
Therefore, to maintain constant expenditure on sugar, a household needs to decrease consumption of sugar by 9% (1 - 0.91)*100%.
