Solving Blood Relation Puzzles

This question involves understanding relationships within a family tree based on a descriptive statement. Let's break down the statement given by Raghav step by step to determine the relationship between Raghav's father and the girl's mother.

Analyzing Raghav's Statement Step-by-Step

Raghav says, "She is my father's mother's daughter's only brother's daughter". We will analyze this statement from Raghav's perspective:

  1. "My father's mother": This is Raghav's grandmother (paternal grandmother).
  2. "My father's mother's daughter": This is Raghav's grandmother's daughter. This person is the sister of Raghav's father. So, this is Raghav's aunt (paternal aunt).
  3. "My father's mother's daughter's only brother": This is Raghav's aunt's only brother. The sister's only brother is the sister's father or the sister's brother. Since this person is the brother of Raghav's paternal aunt, and they share the same mother (Raghav's grandmother), this person must be Raghav's father. (This step assumes Raghav's father is the only son of Raghav's grandmother, which is implied by "only brother" in this context).
  4. "My father's mother's daughter's only brother's daughter": This is Raghav's father's daughter. Raghav's father's daughter is Raghav's sister.

So, the girl in the photograph is Raghav's sister.

Identifying the Required Relationship

The question asks: "How is Raghav's father related to that girl's mother?"

  • We know the girl in the photograph is Raghav's sister.
  • The girl's mother is therefore Raghav's sister's mother.
  • Raghav's sister's mother is Raghav's mother.
  • The question is asking: How is Raghav's father related to Raghav's mother?

Determining the Final Relationship

Raghav's father is married to Raghav's mother. Therefore, Raghav's father is the husband of Raghav's mother (who is also the girl's mother).

Thus, Raghav's father is the husband of that girl's mother.

Statement Part Relationship to Raghav
My father's mother Raghav's Grandmother
... daughter Raghav's Aunt
... only brother Raghav's Father
... daughter Raghav's Sister (The Girl)

The girl is Raghav's sister. The girl's mother is Raghav's mother. Raghav's father is the husband of Raghav's mother.

Additional Information on Blood Relation Problems

Blood relation questions test your ability to decode relationships presented in a complex or indirect manner. These problems often appear in reasoning sections of competitive exams. Here are some tips for solving them effectively:

  • Break down the statement step by step, working backward or forward from the reference person (like 'my' in this case).
  • Use diagrams or family trees to visualize the relationships, especially for more complex problems.
  • Carefully note genders where mentioned, as they are crucial for determining the correct relation (e.g., son vs. daughter, brother vs. sister).
  • Pay attention to possessives like 'my', 'his', 'her' to correctly identify the starting point of the relation chain.
  • Simplify each part of the statement before moving to the next.
