Blood Relation

Reasoning - Blood Relation

What is Blood Relation?

These problems are based on family relationships. They test your logical understanding of kinship and hierarchical relationships.

Types of Blood Relation Questions

1. Descriptive: A long statement is given and you have to deduce relation. 2. Dialogue-based: 'Person A says...' format. 3. Symbol-based: Relationships expressed with symbols like + for father, − for sister, etc.

Example Questions

• A is B’s brother, B is C’s father. How is A related to C?
  Answer: Uncle
• X + Y means X is father of Y; X − Y means X is sister of Y. What does P − Q + R mean?
  Answer: P is aunt of R

Exam Tips

• Draw a family tree diagram or symbol chain for clarity.
• Mark genders clearly if mentioned.
• Follow generation hierarchy: grandparent → parent → child.
• Watch for indirect clues-‘only son’, ‘daughter of the father’s brother’, etc.

Common Mistakes

• Assuming gender when not given.
• Confusing maternal and paternal relationships.
• Reading direction of relation wrongly (A is B’s uncle ≠ B is A’s uncle).

Quick Revision Checklist

• Memorize basic relationships and their chains (uncle, cousin, niece).
• Practice symbol and coded format questions.
• Visualize relationships or use rough diagrams.
• Use table-based deduction for complex chains.

Summary: Blood relation questions measure your grasp of family logic. Clear visualization and careful reading of relational cues are key to solving them quickly and accurately.
