Three years ago, Liam was three times as old as his sister Maya. Today, he is exactly twice as old as her. How old is Maya right now?
6 years old
Let Liam's current age be L and Maya's be M. We know L = 2M and (L - 3) = 3(M - 3). Substituting L gives 2M - 3 = 3M - 9, which simplifies to M = 6. (Liam is 12).
