Answer 2

Given: A 10-year-old girl’s brother is half her age

To find: How old is her brother when she is 50

Solution:

When the sister is ten years old, his younger brother is half her age. This means that her brother is five years old.

The younger brother is five years younger than his sister and so when his sister is 50 years, her brother will be forty-five years old.

The brother will be forty-five years when his sister is fifty years old.
