Problem Analysis

We are given that six years ago, Kolya was three times older than Olya, and now he is twice as old as Olya. We need to determine Olya's current age.

Solution

Let's assume Olya's current age is x years.

According to the given information, six years ago, Kolya was three times older than Olya. This can be expressed as:

Kolya's age six years ago = 3 * Olya's age six years ago

Kolya's age six years ago = Kolya's current age - 6

Olya's age six years ago = Olya's current age - 6

Substituting the values, we get:

Kolya's current age - 6 = 3 * (Olya's current age - 6)

Now, we are given that Kolya is currently twice as old as Olya. This can be expressed as:

Kolya's current age = 2 * Olya's current age

Substituting the values, we get:

2 * Olya's current age - 6 = 3 * (Olya's current age - 6)

Simplifying the equation:

2 * Olya's current age - 6 = 3 * Olya's current age - 18

Rearranging the equation:

Olya's current age = 12

Therefore, Olya is currently 12 years old.

Answer

Olya is currently 12 years old.
