Let`s check out the solution together. In the beginning, the person says that "when they were 4 years old, their brother was half their age". That means the brother was 2 years at that point. Which makes them 2 years younger than their sibling. So, how old is the brother when the sibling is 18 years old?

Yes, The right answer is 16.
