The sum of the ages of 4 children born at the intervals of 3 years each is 38 years. What is the age of the youngest child?
Answer/Solution
5 years
Steps/Work
Let the ages of the children be x, (x + 3), (x + 6), (x + 9) years.
Then, x + (x + 3) + (x + 6) + (x + 9) = 38
4x = 20 => x = 5.
Age of youngest child = x = 5 years.

Then, x + (x + 3) + (x + 6) + (x + 9) = 38
4x = 20 => x = 5.
Age of youngest child = x = 5 years.
