A girl is 21 years old and her brother is a third of her age. What will be the age of her brother when the girl is 36?

The correct answer is: 22

To determine the age of the girl’s brother when she is 36, it’s important to first establish their current ages. The girl is 21 years old, and her brother is one third of her age, which calculates to 7 years old (a third of 21). Now, we need to find out how many years it will take for the girl to reach 36. The difference between her current age (21) and her future age (36) is 15 years. Since both siblings will age the same number of years, the brother will also age 15 years during this time. Starting from his current age of 7, adding 15 years leads us to 22 years. Therefore, the brother will be 22 years old when the girl is 36. This calculation accurately reflects the progression of their ages over time, demonstrating that the correct answer is indeed 22.
