My answer is

None of those.

Here is the family tree

 (A's daughter) (me)
      \         /
     (my daughter)

So A's daughter is my wife.
A is my mother-in-law and I am A's son-in-law.
So I am none of those relations to A, and I am not Teresa because I am a man.

  • $\begingroup$ @Shinjo I'm trying to think if there is anything more of a puzzle to it, like constructing something from letters. $\endgroup$ Jun 24, 2019 at 8:51
  • $\begingroup$ I was thinking that A' was like a mathematic derivative of A or something like that earlier, but I concluded that probably a typo. $\endgroup$

A has a daughter which is your daughter mother.

(A's daughter) [you]
\ / (your daughter)

won't you be:

neither of the choice? But probably you're A's son in law?


Using the information given, I am teresa's daughter.

We are given the information that we are in the middle generation, and out of the choices given, 2 is the only one that fits that criteria.


Well, let's break the sentence down:

"If Teresa's daughter is my daughter's mother, what am I to Teresa?" So daughter's mother means me. So we replace it. "If Teresa's daughter is me, what am I to Teresa?" So obviously, you are Teresa's daughter. That is not one of the question choices.

So the resulting answer is:

None of the above.

  • $\begingroup$ Neither is yours, none of the options work. $\endgroup$
