Problem Analysis

We are given that a kiosk sold 1250 notebooks, with the number of notebooks sold in a ruled format (линейка) being four times the number of notebooks sold in a grid format (клетка). We need to determine the number of notebooks sold in the grid format.

Solution

Let's assume the number of notebooks sold in the grid format is x. According to the given information, the number of notebooks sold in the ruled format is four times x, or 4x.

We know that the total number of notebooks sold is 1250. Therefore, we can write the equation:

x + 4x = 1250

Simplifying the equation, we have:

5x = 1250

To find the value of x, we divide both sides of the equation by 5:

x = 1250 / 5

Solving the equation, we find:

x = 250

Therefore, the number of notebooks sold in the grid format is 250.

Answer

The kiosk sold 250 notebooks in the grid format (клетка).
