Problem Analysis

To solve this problem, we need to determine the initial number of plums (сливы) in the package. We are given that 50% of the plums were taken from the package, and then 50% of the remaining plums were taken, leaving 9 plums in the package.

Solution

Let's assume that the initial number of plums in the package is x.

According to the problem statement, 50% of the plums were taken from the package. This means that 0.5x plums were taken, leaving 0.5x plums in the package.

Then, 50% of the remaining plums were taken. This means that 0.5 * 0.5x = 0.25x plums were taken, leaving 0.5x - 0.25x = 0.25x plums in the package.

We are given that there are 9 plums remaining in the package. So, we can set up the following equation:

0.25x = 9

To find the value of x, we can solve this equation:

0.25x = 9

Dividing both sides of the equation by 0.25, we get:

x = 9 / 0.25

Evaluating the right side of the equation, we find:

x = 36

Therefore, the initial number of plums in the package was 36.

Answer

The initial number of plums in the package was 36.
