There are two types of cottage cheese: fat contains 20% fat, and low-fat – 5%. Mixed 2 kg of fatty cottage cheese and 3 kg of low-fat. What is the fat percentage of the resulting curd?

To solve the problem, you first need to determine the total fat content in each type of cottage cheese in kilograms.
To do this, the amount of cottage cheese that is mixed should be multiplied by the percentage of fat.
In this case, we get:
2 * 20% / 100% = 0.4 kg.

3 * 5% / 100% = 0.15 kg.

Find the total amount of fat in the resulting mixture.
0.4 + 0.15 = 0.55 kg.

We find the total amount of cottage cheese.
2 + 3 = 5 kg.

Determine the percentage.
To do this, divide the amount of fat by the amount of cottage cheese.
We get:
0.55 / 5 = 0.11

0.11 * 100% = 11%.

Answer: 11%.
