Problem Analysis

We are given that the price of apples was initially low in the fall. After the winter, the price increased by a factor of 2, and then in the spring, it increased by a factor of 3. We need to determine the price of apples in the fall.

Solution

Let's assume the price of apples in the fall was x rubles per kilogram.

According to the given information, the price increased by a factor of 2 in the winter, so the price became 2x rubles per kilogram.

Then, in the spring, the price increased by a factor of 3, so the price became 3 * 2x = 6x rubles per kilogram.

Finally, we are given that the price of apples in the end is 180 rubles per kilogram. Therefore, we can set up the equation:

6x = 180

To find the value of x, we can divide both sides of the equation by 6:

x = 180 / 6 = 30

Therefore, the price of apples in the fall was 30 rubles per kilogram.

Answer

The price of apples in the fall was 30 rubles per kilogram.
