Ma'am, in Nov 2017 question, can't old man also be 'Father-in -law' of Rakesh, as his (Rakesh's) son's uncle could also mean maternal uncle. Therefore can't we also say that the old man's son is the maternal uncle of Rakesh's son? And Father-in-law is available in the option too.. So isn't it possible for both the answers to be right?
