Question

2. A milk maid sold 20 litres of milk at the rate of
48.50 per litre and gained 22.00. Find the cost price
of the milk per litre.​

Answer 1

Step-by-step explanation:

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 =S.Pprofit×100

=45090×100=20%
