Give the step-by-step reasoning process and then the final answer. Bush and Matt are brothers. Bush is younger than Matt by 3 years. This year Bush will be 12 years old. What will be Matt's age 10 years from now?

Bush is younger than Matt by 3 years, so if Bush is 12 years old then Matt is 12 + 3 = 15 years old. In 10 years' time, Matt will be 10 + 15 = 25 years old.
The final answer: 25.
