Question

A milkman has 20 litres of milk. If he mixes 5 litres of water, which is freely available, in 20 litres of pure milk. If the cost of pure milk is rs. 18 per litre, then what will be the profit of the milkman, when he sells all the mixture at cp?

Answer 1

Step-by-step explanation:

cost of 20 litres milk =20×18=360

cost of the 25 litres of milk after mixing the water =25×18=450
