Given:
The sum of the ages of five children is 60 years.

The age of the youngest child be x
The next child is x + 3 years old.
The next child is x + 6 years old.
The next child is x + 9 years old.
The oldest child is x + 12 years old.
Sum of the Ages:
x+ (x+3) + (x+6) + (x+9) + (x+12) = 60
5x +30 = 60
5x = 60−30
5x =30
x =
x = 6
The age of the youngest child is 6 years.
