Calculation of Katya's Age

To calculate Katya's current age, we need to analyze the information provided. We know that a year before Katya's birth, her parents' combined age was 40 years. We also know that in 2 years, the combined age of Katya and her parents will be 90 years.

Let's break down the problem step by step:

1. A year before Katya's birth, her parents' combined age was 40 years. 2. In 2 years, the combined age of Katya and her parents will be 90 years.

To find Katya's current age, we can set up the following equation:

Katya's age + (Parents' combined age - 1 year) + 2 years = 90 years

Let's solve this equation to find Katya's current age.

Let's assume Katya's current age is represented by the variable "x."

x + (40 - 1) + 2 = 90

Simplifying the equation:

x + 39 + 2 = 90 x + 41 = 90

Subtracting 41 from both sides of the equation:

x = 90 - 41 x = 49

Therefore, Katya is currently 49 years old.

Please note that the information provided does not specify the current date, so we cannot determine the exact date of Katya's birthday or the accuracy of the calculation.
