Answer:
16.67%
Step-by-step explanation:
Expenditure = Price x Quantity
Let original price of milk is Rs 100 per litre and original quantity of milk = 36 litres
Original Expenditure = Rs 3600
New price of milk after 20% increase is Rs 120 per litre
Since expenditure is same, new quantity is 3600/120 = 30 litres.
Decrease in consumption is 36 - 30 = 6 litres.
=> Percentage decrease = 6/36 x 100 =16.67%
