From 100 g of milk, 21 g of cream is obtained, and from 100 g of cream, 23 g of butter are obtained.

From 100 g of milk, 21 g of cream is obtained, and from 100 g of cream, 23 g of butter are obtained. How many kilograms of milk do you need to take to get 483 kg of butter?

Since the manufacture of 23 g of butter requires 100 g of cream, the manufacture of 483 kg of butter will require:
483,000: 23 * 100 = 2,100,000 (g) cream.
Let’s find how much milk is required to make this amount of cream:
2100000: 21 * 100 = 10000000 (g) = 10000 (kg) = 10 (t) milk.
Answer: 10,000 kg or 10 tons of milk.
