Question

A milkman buys 10 litres of milk at Rs. 50 per litre and sells it at Rs. 60 per litre. He mixes some amount of water to the milk, and ends up making a profit of 32% by selling the entire mixture. How much water did he add to the milk?

Answer 1

Answer:

60%

Step-by-step explanation:

1 litre (Milk) + 1/3 litre (Water) = 4/3 litre (Mixture) buys for Rs 60.00

4/3 litres (Mixture) buys for Rs. 60.00

1 liter (Mixture) buys for Rs. 60/4/3

Or, 1 liter (Mixture) buys for Rs. 60×3/4

Or, 1 liter (Mixture) buys for Rs. 45.00

Cost Price of 1 litre (Mixture) = Rs. 45.00

Selling Price of 1 litre (Mixture) = Rs. 72.00

Gain = Selling Price - Cost Price

Or, Gain = Rs. 72.00 - Rs. 45.00

Or, Gain = Rs. 27.00

Or, Percentage Gain = 27.00/45 × 100

Or, Percentage Gain = 60%

Therefore, the Gain = Rs. 27.00 and Percentage Gain = 60%
