If X's mother is the only daughter of Y's father, then Y's husband's sister is X's _________.
Understanding the Blood Relation Puzzle
Blood relation questions test your ability to decipher the relationships between different individuals based on a given set of information. These questions often involve building a small family tree or tracing connections step-by-step.
Analysing the Given Statement
The core statement provided is: "If X's mother is the only daughter of Y's father". Let's break this down:
- Consider Y's father.
- Y's father has an "only daughter". This means Y's father has only one female child.
- This "only daughter" of Y's father is identified as X's mother.
If Y is a child of Y's father, and Y's father has only one daughter, then Y must be that only daughter. Therefore, Y is the only daughter of Y's father.
Combining this with the statement, we find that X's mother is Y.
Establishing Key Relationships
From the analysis above, we have determined a crucial relationship:
Relationship 1: Y is X's mother.
Tracing the Final Relationship
The question asks for the relationship of "Y's husband's sister" to X.
- We know Y is X's mother.
- Therefore, Y's husband is X's father.
- Now consider Y's husband's sister. This is X's father's sister.
Let's summarise these steps in a table for clarity:
| Individual(s) | Relationship to X | Reasoning |
|---|---|---|
| Y | Mother | Y is the only daughter of Y's father, and X's mother is the only daughter of Y's father. |
| Y's Husband | Father | Y is X's mother, so her husband is X's father. |
| Y's Husband's Sister | Father's Sister (Aunt) | The sister of X's father is X's Aunt. |
Conclusion
Based on the step-by-step analysis of the blood relations, Y's husband's sister is the sister of X's father. The sister of one's father is their Aunt.
Therefore, Y's husband's sister is X's Aunt.

Additional Information on Blood Relation Puzzles
Solving blood relation problems efficiently often involves drawing a simple family tree or using symbolic representations. For example, you can use arrows to indicate relationships or use symbols for gender.
