Solution
The problem is asking to find out Chefina's age when Chef will be X years old. Chef's current age is 2020 years and Chefina's current age is 1010 years. They were born on the same day and month, just different years.
Here are the steps to solve this problem:
- First, we need to understand the age difference between Chef and Chefina. Chef is 2020 years old and Chef
