A father is now three times as old as his son. In 12 years he will be twice as old as his son. How old is the son now?

Correct answer: A. 12

Let the son's age be x, so the father is 3x. In 12 years: 3x + 12 = 2(x + 12) = 2x + 24, so x = 12. Check: father 36 and son 12 now; in 12 years they will be 48 and 24.
