Introduction to Simple Relation ID

Simple Relation ID problems give direct relationship statements between two individuals. You must identify the relationship of one person to another. These problems form the foundation of blood relation puzzles and test your knowledge of basic family terms.

Prerequisites

Knowledge of basic family relations (father, mother, brother, sister, son, daughter) Understanding of gender-specific terms Ability to reverse relationships (A is B's father → B is A's child)
Why This Matters: Simple Relation ID problems are the most fundamental type of blood relation puzzles. You can expect 2-3 questions in SSC CGL, 2-3 in Banking PO, and 2-3 in Railways RRB exams.

How to Solve Simple Relation ID Problems

1

Step 1: Identify the two persons involved in the relationship (A and B)

2

Step 2: Note the given relationship statement (e.g., 'A is the father of B')

3

Step 3: Determine the gender of the person whose relationship is being asked (if relevant)

4

Step 4: Reverse the relationship to find how B is related to A

5

Step 5: Apply the correct gender-specific term (e.g., if A is father, B could be son or daughter)

6

Step 6: For sibling relationships, remember that 'brother' implies male, 'sister' implies female

7

Step 7: Verify the relationship by constructing a small family tree

Pro Strategy: Always reverse the relationship. If A is parent of B, then B is child of A. Pay attention to gender—if not specified, the answer may have multiple possibilities.

Example Problem

Example: 'A is the mother of B.' How is B related to A? Solution: Step 1: Persons: A and B Step 2: Given: A (mother) is parent of B Step 3: Reverse: B is child of A Step 4: Since A is mother (female), B can be son or daughter Step 5: Without gender of B, answer is 'child' or 'son/daughter' Answer: B is the son or daughter of A (or child of A)

Pro Tips & Tricks

  • Parent-child relationships are reversible: father → son/daughter, mother → son/daughter
  • Sibling relationships: brother → brother/sister, sister → brother/sister
  • If the gender of the person is unknown, use gender-neutral terms like 'child' or 'sibling'
  • Draw a small family tree with symbols: □ for male, ○ for female, = for married, | for parent-child
  • Common relationships to memorize: father/mother → child; brother/sister → sibling; husband/wife → spouse
  • For 'only child' or 'only son/daughter' clues, pay special attention as they imply uniqueness

Shortcut Methods to Solve Faster

Parent → Child: reverse gives child
Sibling → Sibling: reverse gives sibling
Spouse → Spouse: reverse gives spouse
Grandparent → Grandchild: reverse gives grandchild

Common Mistakes to Avoid

Forgetting that 'child' can be son or daughter when gender is unknown
Assuming a person is male when not specified
Confusing 'aunt/uncle' relationships with parent-child
Misidentifying the direction of the relationship (e.g., 'A is brother of B' vs 'B is brother of A')
