Answer 2

Problem Analysis

To solve this problem, we need to find the ages of the father and the son. We are given two pieces of information: 1. The father is 20 years older than the son. 2. The son is younger than the father by a factor of 5.

Let's assume the son's age is represented by x. According to the given information, the father's age would be x + 20. Additionally, we know that the son is younger than the father by a factor of 5, so we can write the equation: x + 5x = x + 20.

Solving the Equation

To find the value of x, we can solve the equation x + 5x = x + 20.

Combining like terms, we get 6x = x + 20.

Subtracting x from both sides, we get 5x = 20.

Dividing both sides by 5, we find that x = 4.

Answer

Therefore, the son is 4 years old. To find the father's age, we can substitute x = 4 into the equation x + 20. Thus, the father is 4 + 20 = 24 years old.

So, the father is 24 years old and the son is 4 years old.
