This is a logic puzzle. YOU are part of the puzzle, so you have equal brothers and sisters. Your brothers have twice as many sisters (meaning you) as they have brothers. So if you have one brother and one sister, they are equal. But if your brother has two sisters, he has twice as many sisters as brothers, right? It doesn't say that he HAS brothers, just that he has twice as many sisters as brothers. So you have a brother and a sister, but your brother has two sisters. Three kids, two girls and one boy.
