1070.12 – This Man's Father

Tags:Problem Set 3Algebra ILogic

Brandon Hoyte shows a photograph of a man to a friend and says, “Brothers and sisters have I none, but this man’s father is my father’s son.” What relation is Brandon to the man in the photo?


Brandon has no brothers or sisters, so “my father’s son” must be Brandon himself. Therefore, “this man’s father” – “this man” being the man in the photo – is “my father’s son,” that is, Brandon himself. So, the photo is a picture of Brandon’s son.
