Blood Relations & Direction Sense

1. Blood Relations

Concept Overview

Blood relation questions are based on family connections. You are given clues or statements about how individuals are related, and you must identify specific relationships.

Key Family Relationships
Relationship Male Female
Parent Father Mother
Sibling Brother Sister
Child Son Daughter
Grandparent Grandfather Grandmother
Uncle/Aunt Uncle (Father's/Mother's brother) Aunt (Father's/Mother's sister)
In-laws Father-in-law, Brother-in-law Mother-in-law, Sister-in-law
Others Nephew, Son-in-law Niece, Daughter-in-law

Grandparents Father Mother Son Daughter Son
Common Question Types

Statement-based:
Example: "A is the brother of B. B is the sister of C. How is A related to C?"

Puzzle/Symbol-based:
Example: "A + B means A is the mother of B. A * B means A is the sister of B."

Short Tricks for Blood Relations
  • Always start drawing the family tree from the person mentioned first
  • Use gender-specific terms carefully (brother/sister, uncle/aunt)
  • For complex relations, work backwards from the person in question
  • Remember that "only son/daughter" means no other children of that gender
  • In-laws are always connected through marriage relationships
Sample Question

Q: A is the brother of B. C is the sister of A. D is the father of C. How is D related to B?

A: D is the father of B.

2. Direction Sense Test

Concept Overview

Direction Sense questions evaluate your ability to trace directions and determine final positions and orientations based on given movement instructions.

Important Basics

Main Directions:

Cardinal (Intermediate) Directions:

Direction Diagram

North South East West NE NW SE SW
Key Observations & Sunlight-Based Clues
Left–Right Movement Rules
Facing Direction Turns Left Turns Right
North West East
South East West
East North South
West South North

Turning left → anticlockwise

Turning right → clockwise

Turns are always considered 90°, unless otherwise stated.

Distance-Based Problems

To find the shortest distance (usually when movements are in perpendicular directions), use the Pythagorean theorem:

Distance = √(x² + y²)
Short Tricks for Direction Sense
  • Always draw the path step-by-step on paper
  • Mark the starting point clearly
  • For turns, imagine yourself in that position
  • Remember sunrise = East, sunset = West for shadow problems
  • For shortest distance, use Pythagoras theorem when movements are perpendicular
Sample Questions

Q1: A person walks 5 km North, then turns right and walks 3 km, then turns right again and walks 5 km. Which direction is he facing now?

A: South

Q2: A person starts walking from point A towards East for 4 km, then turns left and walks 6 km. What is the shortest distance between the starting point and the final position?

A: The shortest distance is 7.21 km (using the Pythagorean theorem).
