•Suppose the price of a sugar is = 100rs
•Sugar cost increased by 20% so the cost of sugar is 120
• The family decreased sugar consumption by 25%
• So expenditure = Price × Quantity
100× 100= 10000
• New expenditure = 120× 75= 9000
Decrease in expenditure and sugar value decreased by {(10000-9000)/ 10000}× 10
1000/1000×100
0.1× 100
10%
