Maya is twice as old as her brother Liam was when Maya was as old as Liam is now. If Maya is currently 24 years old, how old is Liam right now?
18 years old
Let Maya's current age be M = 24 and Liam's current age be L. The age difference is (24 - L). When Maya was L years old, Liam was L - (24 - L) = 2L - 24 years old. The riddle states Maya (24) is twice Liam's age back then: 24 = 2 * (2L - 24), which simplifies to 12 = 2L - 24, giving 2L = 36, so L = 18.
