Answer 2

Question :

Chandu, 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 what is the profit of the milkman, when he sells all the mixture at cost price.

Answer :

Profit of the milkman is Rs.90 and the profit % is 20%.

Given :

Volume of milk Chandu has = 20 litres

He mixes 5 liters of water, which is freely available, in 20 liters of pure milk.

The cost of pure milk is Rs. 18 per litre.

To find :

The profit of the milkman, when he sells all the mixture at cost price.

Solution :

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 = Rs.360

Cost of the 25 litres of milk after mixing the water = 25 × 18 = Rs.450

Profit = Rs.450 - Rs.360

= Rs.90

We know,

Profit percent = profit / C.P × 100

= 90/450 × 100

= 90/9 × 2

= 10 × 2

= 20 %

Hence, profit of the milkman is Rs.90 and the profit % is 20%.
