Question 882679: a son is 1/4 of his fathers age the difference in their ages is 30 years what is the fathers age? Answer by Leaf W.(135) (Show Source):
You can put this solution on YOUR website! Let us call the father's age x. Since the son, is 1/4 of his father's age, we can call the son's age . Since the difference in their ages is 30 years (that is, father's age - son's age = 30), we can say that
Now just simplify:
x = 40
Therefore, the father's age is 40 years, and the son's age is years.
