Blood Relations

🏠 Blood Relations: The Family Detective Guide

Imagine your family is like a big tree. You are a branch, your parents are the trunk, and your grandparents are the roots. Understanding blood relations is like being a detective who figures out how everyone in the family tree is connected!

🎯 What Are Blood Relations?

Think of your family like a team. Everyone has a special role!

Simple Example:

• Your mom’s brother = Your Uncle
• Your dad’s sister = Your Aunt
• Your uncle’s son = Your Cousin

Blood relation problems ask you to find how two people are connected. It’s like solving a puzzle about a family!

📚 Part 1: Blood Relation Basics

The Family Words You Need to Know

Think of these like your detective vocabulary:

The Magic Rule: Same Generation = Cousins!

Example: Ram says, “My mother’s brother’s daughter is Priya.”

Let’s solve step by step:

1. My mother’s brother = My Uncle
2. My uncle’s daughter = My Cousin
3. So Priya is Ram’s Cousin!

Quick Tip: Count the Steps!

Me → Parent → Parent's Sibling → Their Child
     (1 up)    (same level)      (1 down)
                  = COUSIN

🌳 Part 2: Family Tree Problems

What is a Family Tree?

A family tree is a picture that shows how everyone is connected. Like a map of your family!

graph TD
    A["Grandfather 👴"] --- B["Father 👨"]
    A --- C["Uncle 👨"]
    B --- D["You 🧒"]
    B --- E["Sister 👧"]
    C --- F["Cousin 🧒"]

How to Draw a Family Tree

Step 1: Put the oldest people at the TOP

Step 2: Draw lines DOWN for children

Step 3: Draw lines SIDEWAYS for husband-wife

Example Problem:

“A is B’s father. B is C’s sister. D is A’s father.”

Let’s draw it:

graph TD
    D["D - Great Grandfather"] --> A["A - Father/Grandfather"]
    A --> B["B - Daughter"]
    A --> C["C - Son"]

Answer: D is C’s Grandfather!

The Golden Rules for Family Trees

🔹 Rule 1: Husband and Wife are on the SAME level (draw a horizontal line)

🔹 Rule 2: Children go ONE level DOWN

🔹 Rule 3: Siblings (brothers/sisters) are on the SAME level

Practice Example:

“Pointing to a photo, Ram said: She is the daughter of my grandfather’s only son.”

Solution:

1. My grandfather’s only son = My Father
2. My father’s daughter = My Sister
3. Answer: She is Ram’s Sister!

🔐 Part 3: Coded Blood Relations

What Are Coded Blood Relations?

Sometimes puzzles hide family relationships using secret codes! Like a spy mission for family detectives!

Common Codes:

How to Crack the Code

Step 1: Write down what each symbol means

Step 2: Replace symbols with real words

Step 3: Solve like a normal problem

Example:

If A + B means A is father of B If A - B means A is mother of B If A × B means A is brother of B

What is C to A in: A + B × C

Solution:

1. A + B = A is father of B
2. B × C = B is brother of C
3. So B and C are siblings
4. A is father of both B and C
5. Answer: C is A’s Child (son or daughter)!

Another Code Type: Direction Codes

Sometimes they use directions!

Example:

“P is to the East of Q” means P is Q’s father “P is to the West of Q” means P is Q’s mother

Just replace the directions with the relationship and solve!

Tricky Coded Problem:

If ‘+’ means brother If ‘-’ means sister If ‘×’ means father If ‘÷’ means mother

How is D related to A in: A × B - C + D

Step by step:

1. A × B = A is father of B
2. B - C = B is sister of C (so C is B’s sibling, A’s child too)
3. C + D = C is brother of D (so D is C’s sibling)
4. D is also A’s child!

Answer: D is A’s Child!

💡 Super Detective Tips

Tip 1: Always Start with “I” or the Main Person

When someone says “my mother’s…”, start from that person and trace the path.

Tip 2: Use Arrows

• ↑ = Going UP (to parents)
• ↓ = Going DOWN (to children)
• ← → = SAME level (siblings, spouse)

Tip 3: Watch for Tricky Words

Tip 4: Gender Matters!

• “Only son” = definitely MALE
• “Only child” = could be male or female
• Pay attention to he/she in the question!

    B --> C["Grandparents"]
    end
    subgraph "Same Level ↔️"

    E["Cousin"]
    F["Spouse"]
    end
    subgraph "Going DOWN ⬇️"
    G["Children"]
    H["Grandchildren"]
    end

🏆 You’re Now a Family Detective!

Remember these three skills:

1. Basics: Know your relation words (uncle, aunt, nephew, niece, cousin)

2. Trees: Draw pictures with oldest at top, youngest at bottom

3. Codes: Replace symbols with real words, then solve!

Every family is like a puzzle. Once you know the pieces, you can solve any mystery! 🕵️
