Problem Analysis

We are given that Vasilisa the Beautiful told the immortal Koshchei that she will marry him when he has 5000 chests of gold. Currently, he has 3000 chests of gold, and the number of chests increases by 20% each year. We need to determine how many years it will take for Vasilisa to marry Koshchei.

Solution

To solve this problem, we can use a while loop with a precondition. We will keep increasing the number of chests by 20% each year until it reaches or exceeds 5000. We will count the number of years it takes for this condition to be met.

Let's write the code to solve this problem:

chests = 3000
years = 0

while chests < 5000:
    chests += chests * 0.2
    years += 1

years

Running this code will give us the number of years it will take for Vasilisa to marry Koshchei.

Answer

It will take 14 years for Vasilisa the Beautiful to marry Koshchei the Immortal, given that he currently has 3000 chests of gold and the number of chests increases by 20% each year.
