Question
The sum of the ages of a father and his son is 50 years.
Five years ago, the father's age was four times that of his son. What are their current ages?Solution
Let the son's current age be x years. Then, the father's current age is (50 - x) years. Five years ago, the father's age was (50 - x - 5) and the son's age was (x - 5). According to the problem: (50 - x - 5) = 4(x - 5) 45 - x = 4x - 20 45 + 20 = 5x x = 13 So, the son's current age is 13 years, and the father's current age is 37 years. Correct answer: c) Father: 37 years, Son: 13 years
