Introduction to Blood Relations

Blood Relations in Ranking puzzles combine family relationship concepts with ordering and ranking. You must arrange family members by generation, age, or position while tracking family ties like parent-child, sibling, or grandparent-grandchild relationships.

Prerequisites

Blood relation basics (father, mother, son, daughter, etc.) Generational concepts Ranking fundamentals Family tree construction
Why This Matters: Blood Relations with ranking appear in 1-2 questions in Banking and SSC exams. They test integration of relationship logic with ordering.

How to Solve Blood Relations Problems

1

Step 1: Identify all family members mentioned

2

Step 2: Build a family tree showing generational relationships

3

Step 3: Note that parents are always older than children (generation gap)

4

Step 4: Use age/ranking clues to order within generations

5

Step 5: Combine generational hierarchy with positional/ranking order

6

Step 6: Determine the complete ordering from oldest to youngest

7

Step 7: Answer the specific question (who is oldest, who is in middle, etc.)

Pro Strategy: First establish the generational hierarchy. Parents are always older than children. Within the same generation, use additional clues (age comparisons) to determine order. Combine to get complete ordering from oldest to youngest.

Example Problem

Example: A is the father of B and C. D is the son of B. E is the daughter of C. Who is the oldest? Solution: Step 1: Family tree: A (generation 1), B and C (generation 2), D and E (generation 3) Step 2: Oldest is from generation 1 Step 3: A is the only person in generation 1 Step 4: Therefore, A is the oldest Answer: A is the oldest

Pro Tips & Tricks

  • Parents are always one generation above children
  • Grandparents are two generations above grandchildren
  • Within same generation, siblings have no inherent age order
  • Father, mother, uncle, aunt are all one generation above
  • Son, daughter, nephew, niece are one generation below
  • Age order within generation may need additional clues

Shortcut Methods to Solve Faster

Generation number determines approximate age range
Parent > Child (always true)
Grandparent > Grandchild (always true)
If only one person in highest generation, they are the oldest
If multiple in same generation, compare using given clues

Common Mistakes to Avoid

Assuming parents are older than children by exact numbers (just older)
Confusing generation levels
Forgetting that siblings are in same generation
Assuming age order within generation without clues
