Q: In seven years, Talia will be 20 years old. Talia's mom is currently three times as old as Talia is today. In three years, Talia's father will be the same age as Talia's mom is today. Currently, how many years old is Talia's father?
A: In seven years, Talia will be 20 years old, and therefore Talia is currently 20 - 7 = 13 years old. Talia's mom is currently three times as old as Talia is today, or 3 * 13 = 39 years old. If in three years, Talia's father will be the same age as Talia's mom is today, then Talia's father is currently 39 - 3 = 36 years old. The answer is 36.
