Blood Relationship 
& Coded 
Relationship
Introduction
Blood Relations
Connections between people 
either through birth (parents, 
siblings, children) or through 
marriage (in-laws). These 
questions test your intelligence 
and logical reasoning abilities.
Three Basic Relationships
Parent-child relationship, 
husband-wife relationship, and 
sibling relationships (brother-
brother, brother-sister, or sister-
sister). Gender identification is 
crucial in solving these problems.
Examination Focus
Questions test your ability to see 
through complex relationship 
webs. You must determine 
relationships between two people 
based on given information.

Blood Relations Topics
Family Tree Basics
A family tree is a visual 
representation showing family 
connections. It typically starts with 
older generations at the top and 
proceeds to younger generations at 
the bottom. Icons represent 
individuals, with horizontal lines 
showing partnerships and vertical 
lines showing parent-child 
relationships.
Key Components
Individuals: Each icon represents 
a family member
Couple Connections: Horizontal 
lines show partnerships
Parent-Child: Vertical lines 
connect parents to children
Siblings: Connected to same 
parents on same level
Generations: Different levels 
represent different generations

Diagrammatic 
Representation
Male 
Representation
Males are typically 
represented by 
hexagons, squares or 
rectangles in family 
tree diagrams. This 
standardized system 
helps avoid confusion 
when solving blood 
relationship problems.
Female 
Representation
Females are typically 
represented by circles 
or ovals in family tree 
diagrams. This clear 
distinction helps in 
tracking gender-
specific relationships.
Relationship 
Lines
Horizontal broken 
lines represent 
marriages or 
partnerships, while 
vertical lines show 
parent-child 
relationships. This 
standardized system 
creates clarity when 
mapping complex 
family structures.

Types of Blood Relations
Type 1: Jumbled Relationships
These involve direct relationships where 
you must determine the exact 
connection between two people. 
Examples include phrases like "my 
father's only son" (referring to oneself 
or one's brother) or "my son's mother" 
(referring to one's wife).
Solving Methods
Two approaches work best: the pictorial 
method (drawing family trees) and the 
analytical method (logical deduction). 
Begin with pictorial methods to 
understand patterns, then advance to 
analytical methods for speed and 
efficiency.
Complex Example
In problems like Rita meeting "the 
youngest daughter of the brother-in-law 
of my friend's mother," drawing a family 
tree reveals the relationship is "cousin." 
Identifying intermediate relationships 
helps establish connections between 
the required persons.
