Answer:
9% (approx)
Step-by-step explanation:
Let Consumption be 10 kg per month
Let price of sugar be 100 rupees
Expenditure before increase in price = 100*10 = 1000
Cost of sugar per kg after increase = *100=110
Expenditure after increase in price = 110*10=1100
Sugar to be used by house wife so that the expenditure remains same =
= 9.09 kg
Reduction in sugar = 10-9.09 = 0.89 kg
Percentage of sugar reduction = *100 = 8.9%
