A father's age is currently three times his daughter's age. In 12 years, the father will be exactly twice as old as his daughter. How old is the daughter right now?
12 years old
Let the daughter's current age be D. The father's age is 3D. In 12 years: 3D + 12 = 2(D + 12). Solving 3D + 12 = 2D + 24 gives D = 12.
