Problem Analysis

The problem states that in 2 years, the person's brother will be twice as old as he was 2 years ago, and in 3 years, the person will be three times as old as he was 3 years ago. We need to determine the current ages of the person and their brother.

Solution

Let's assume the current age of the person is x years and the current age of their brother is y years.

According to the problem, in 2 years, the brother will be twice as old as he was 2 years ago. This can be represented as:

y + 2 = 2(y - 2)

Simplifying the equation:

y + 2 = 2y - 4

2 = y - 4

y = 6

So, the current age of the brother is 6 years.

Now, let's determine the current age of the person. According to the problem, in 3 years, the person will be three times as old as they were 3 years ago. This can be represented as:

x + 3 = 3(x - 3)

Simplifying the equation:

x + 3 = 3x - 9

12 = 2x

x = 6

So, the current age of the person is also 6 years.

Answer

Therefore, the current age of the person is 6 years and the current age of their brother is also 6 years.
