Lizzy: Thomas is 6 years old. His older sister, Shay, is 13 years older than him and 5 years younger than their older brother, James. How old will James be by the time Thomas reaches his current age?.
Me: Hmmm, let me think. I think this is the detailed solution:
Shay is 6 + 13 = 19 years old. James is 19 + 5 = 24 years old. Thomas will be 24 in 24 - 6 = 18 years. James will be 24 + 18 = 42 years old. Final answer: 42.
