Answer 2

Problem Statement

The father is currently three times older than his son. In 10 years, the sum of their ages will be 80. We need to determine the son's current age.

Solution

Let's assume the son's current age is x years. According to the problem statement, the father is currently three times older than the son, so the father's current age is 3x years.

In 10 years, the son's age will be x + 10 years, and the father's age will be 3x + 10 years. The sum of their ages in 10 years will be 80, so we can write the equation:

(x + 10) + (3x + 10) = 80

Simplifying the equation:

4x + 20 = 80

Subtracting 20 from both sides:

4x = 60

Dividing both sides by 4:

x = 15

Therefore, the son is currently 15 years old.

Answer

The son is currently 15 years old.

Explanation

According to the problem statement, the father is currently three times older than the son. In 10 years, the sum of their ages will be 80. By solving the equation, we found that the son is currently 15 years old.
