Answer is 20% i.e., we can see it using an example
Price * Consumption=Expenditure i.e., If price and consumption are 10 each then expenditure will be 100 and if price increases by 25% means it become 12.5 so in order to make expenditure 100 we have to divide 100 by 12.5 i.e., 8 so consumption becomes 8 hence it is reduced by 20% i.e, (12.5 * 8 = 100)
