If A says that his mother is the daughter of B's mother, then how is B related to A?

Understanding the Relationship Puzzle

This question involves deciphering a family relationship based on a statement made by A.

Analyzing A's Statement

A states: "My mother is the daughter of B's mother." Let's break this down:

  • Identify B's Mother's Daughter: The daughter of B's mother is B's sister.
  • Equate the Relationships: According to A, A's mother is the same person as B's sister.
  • Determine B's Relation to A's Mother: If A's mother is B's sister, then B must be the sibling (brother or sister) of A's mother.

Determining B's Relation to A

The sibling of one's mother is their aunt or uncle.

  • If B is the brother of A's mother, B is A's Uncle.
  • If B is the sister of A's mother, B is A's Aunt.

Since B's gender isn't specified, both possibilities exist.

Final Conclusion

Based on the analysis, B can be either A's Uncle or A's Aunt.
