In response to a question about the age of his children, the mathematician answered:

- My wife and I have three children. When our first child was born, the total age of the family members was 45 years, a year ago, when the third child was born - 70 years, and the current total age of the children is 14 years.

How old is each child, given that all family members have their birthdays on the same day? #
A year ago, the total age of the children was 11 years, which means the parents' total age was 59 years. And on the day of the first child's birth, this sum was 45. Therefore, the time between these two events is (59 - 45) : $2=7$ years. Thus, the first child was 7 years old a year ago, and the second was 4.

## Answer

8 years, 5 years, 1 year
