Problem Analysis

We are given that 400 grams of cottage cheese (творог) was purchased for 24 rubles. We need to determine the selling price of the cottage cheese.

Solution

To find the selling price, we can set up a proportion using the given information. Let's assume the selling price is x rubles.

The proportion can be set up as follows:

400 grams / 24 rubles = x grams / x rubles

To solve for x, we can cross-multiply and solve for x.

Calculation

Cross-multiplying the proportion, we get:

400 * x = 24 * x

Simplifying the equation, we have:

400x = 24x

Dividing both sides of the equation by 24x, we get:

400 = x

Therefore, the selling price of the cottage cheese is 400 rubles.

Answer

The cottage cheese is sold for 400 rubles.
