Solution
Price of cold-drink in first year = ₹ 8.00 per litre.
∴ Quantity of cold-drink in first year = 2400/8.00 = 300 litres
Price of cold-drink in second year = ₹ 12.00 per litre.
∴ Quantity of cold-drink in second year = 2400/12.00 = 200 litres
Price of cold-drink in third year = ₹ 16.00 per litre.
∴ Quantity of cold-drink in third year = 2400/16.00 = 150 litres
