A milkman has 20 liters of milk. If he mixes 5 liters of water, which is freely available, in 20 liters of pure milk. If the cost of pure milk is Rs. 18 per litre, then the profit of the milkman, when he sells all the mixture at cost price, is:
Answer
When the water is freely available and all the water is sold at the price of the milk, then the water gives the profit on the cost of 20 litres of milk.
cost of 20 litres milk =20×18=360
cost of the 25 litres of milk after mixing the water=25×18=450
profit percent = profile/sp ×100
=90/450 ×100=20%
