If A says that his mother is the only daughter of B's mother, how is B related to A?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Maternal Uncle
Read the statement from the end: “the only daughter of B’s mother” is a daughter of B’s mother, so she is B’s sister (or B herself).
A’s mother is that only daughter, so A’s mother and B are children of the same mother.
B’s mother has only one daughter, and she is A’s mother; so B, if a different person, cannot be a daughter: B is a son, the brother of A’s mother.
The brother of one’s mother is one’s maternal uncle.
