Questions & Step-by-Step Solutions

The age of a father is twice the age of his son. If the sum of their ages is 60 years, how old is the son?
Correct Answer: 20
  • Step 1: Let the son's age be represented by the variable x.
  • Step 2: Since the father's age is twice the son's age, we can represent the father's age as 2x.
  • Step 3: According to the problem, the sum of their ages is 60 years. We can write this as an equation: x + 2x = 60.
  • Step 4: Combine the terms on the left side of the equation: 3x = 60.
  • Step 5: To find the value of x (the son's age), divide both sides of the equation by 3: x = 60 / 3.
  • Step 6: Calculate the result: x = 20.
  • Step 7: Therefore, the son is 20 years old.
