Problem Analysis

The problem states that a chef prepared 56 pancakes. Out of these, 12 pancakes were filled with cottage cheese (tvorog), and the number of pancakes filled with meat was twice the number of pancakes filled with cottage cheese. The remaining pancakes were filled with jam (varenie). We need to determine how many pancakes were filled with jam.

Solution

Let's denote the number of pancakes filled with cottage cheese as x. According to the problem, the number of pancakes filled with meat is twice the number of pancakes filled with cottage cheese. Therefore, the number of pancakes filled with meat is 2x.

We know that the total number of pancakes prepared is 56. So we can write the equation:

x + 2x + y = 56

Where y represents the number of pancakes filled with jam.

Simplifying the equation, we get:

3x + y = 56

We also know that the number of pancakes filled with cottage cheese is 12. So we can write another equation:

x = 12

Substituting the value of x in the first equation, we get:

3(12) + y = 56

Simplifying further:

36 + y = 56

Subtracting 36 from both sides of the equation:

y = 56 - 36

y = 20

Therefore, the chef prepared 20 pancakes filled with jam.

Answer

The chef prepared 20 pancakes filled with jam.
