Problem Analysis

To solve this problem, we can use algebraic equations to represent the relationship between the father's and son's ages. We are given two pieces of information: 1. The father is 4 times older than the son. 2. In 5 years, the sum of their ages will be 60.

Let's represent the son's current age as x. According to the given information, the father's current age is 4x.

Equations

1. The father's current age: 4x 2. The son's current age: x 3. In 5 years, the sum of their ages will be 60: (4x + 5) + (x + 5) = 60

Solution

Let's solve the equation to find the son's current age.

Solving the Equation

``` (4x + 5) + (x + 5) = 60 5x + 10 = 60 5x = 50 x = 10 ```

Answer

The son is currently 10 years old.
