Ans: 20%
Explantion: der's an increase of 25% in the rate of Daal.
Working with examples
eg. let the family consume 5kg of Daal previous month.. so der total expenditure would be Rs 80.
Now after the hike in price, dey can only buy 4kg of Daal keeping in mind the Constant factor of expenditure, which is 20% less to the previous month Quantity(i.e 5kg). So in order to Nullify that % the family will have to reduced their Consumption by 20%
