During cooking, meat loses 40℅ of its mass. How much raw meat do you need to take to get 510 g of boiled meat?

It is known from the condition that meat loses 40% of its mass during cooking. In order to find how much raw meat you need to take in order to get 510 grams of boiled meat, let’s compose and decide the proportion.

Let’s use the variable x to denote the weight of fresh meat and take it as 100%.

Let’s find how many percent of fresh meat is boiled meat:

100 – 40 = 60%.

Let’s compose and solve the proportion.

x gram – 100%;

510 grams – 60%;

x / 510 = 100/60;

We are looking for an unknown extreme member of the proportion:

x = (510 * 100) / 60 = 51000/60 = 850 grams of fresh meat you need to take.
