1. A father has three sons, born on the same day but in different years. The youngest son is 2 years old. In 12 years, the father's age will be equal to the sum of the ages of his three sons. Determine the current ages of the middle and oldest sons, given that the father is currently 33 years old.
Answer: 3 and 4. Solution. In 12 years, the father will be 45 years old, and the youngest son will be 14. The remaining sons will be a total of 31 years old. Since each is older than 14 years, this is only possible if they are 15 and 16 years old. Therefore, they are currently 3 and 4 years old.
