Question
Maggie is 21, and her brother Luis is double her age. How old will Luis be when Maggie is 40?
Solution
Sure, here are the steps to solve the problem:
- First, we know that Luis is double Maggie's age. So, Luis is currently 21 * 2 = 42 years old.
- We want to find out how old Luis will be when Maggie is 40.
- The difference in age between Maggie's current age (21) and the age we want her to be (40) is 40 - 21 = 19 years.
- So, in 19 years, when Maggie is 40, Luis will be 42 (his current age) + 19 = 61 years old.
So, Luis will be 61 when Maggie is 40.
