Question: Beau's sons are triplets. They are 16 years old today. Three years ago, the sum of his 3 sons' ages equaled Beau's age. How old is Beau today? Think carefully first, then make a decision:
Three years ago, his sons were 16 - 3 = 13 years old. Three years ago, Beau was 13 + 13 + 13 = 39 years old. Today, Beau is 39 + 3 = 42 years old. So the answer is 42.
