Problem Analysis

To solve this problem, we need to find the selling price of cottage cheese (tvorog) given that 400 grams of cottage cheese were sold for 84 rubles. We can find the price per gram by dividing the total price by the total weight.

Solution

To find the price per gram, we divide the total price by the total weight:

Price per gram = Total price / Total weight

In this case, the total price is 84 rubles and the total weight is 400 grams. Let's calculate the price per gram:

Price per gram = 84 rubles / 400 grams

To find the selling price of cottage cheese, we multiply the price per gram by the weight of the cottage cheese being sold. In this case, the weight is not given, so we cannot calculate the selling price without that information.

Please provide the weight of the cottage cheese being sold so that we can calculate the selling price.
