Direction Sense: Full-Length Notes

Topics Covered:

  • Distance and Direction

  • Shadow-Based Questions

1. Introduction to Direction Sense

Direction Sense is a fundamental topic in logical reasoning and aptitude exams. It tests your ability to visualize and interpret movements, turns, and relative positions on the basis of cardinal directions (North, South, East, West) and their combinations (North-East, South-West, etc.)456.

2. Basics of Directions

  • Four Main Directions: North (N), South (S), East (E), West (W)

  • Four Intermediate Directions: North-East (NE), North-West (NW), South-East (SE), South-West (SW)

  • Reference Point: The starting position is usually taken as the reference point.

  • Right and Left Turns: Always consider the direction the person is currently facing to determine right and left4.

3. Distance and Direction Problems

A. Understanding Movement

  • Straight Movement: The person moves in a specified direction (e.g., 5 km North).

  • Turning: Right turn means a 90° turn to the right from the current direction; Left turn means a 90° turn to the left46.

  • Multiple Turns: Visualize or sketch the path step-by-step.

Example 1:

A man walks 5 km toward south and then turns to the right. After walking 3 km he turns to the left and walks 5 km. Now in which direction is he from the starting place?
Solution:

  • 5 km South

  • Right turn → West, 3 km

  • Left turn → South, 5 km
    He is facing South from the starting point14.

Example 2:

Sandeep walks 60 m to the east, then turns left and walks 50 m, then turns right and goes 70 m, then turns right again and goes 50 m. How far is Sandeep from the starting point?
Solution:

  • 60 m East

  • Left → North, 50 m

  • Right → East, 70 m

  • Right → South, 50 m
    Total East = 60 + 70 = 130 m. Vertical displacement cancels (50 N, 50 S).
    Answer: 130 m East from starting point2.

Key Points:

  • Right Turn: From North → East, East → South, South → West, West → North

  • Left Turn: From North → West, West → South, South → East, East → North

B. Calculating Distance

  • Use the Pythagoras theorem for shortest (straight-line) distance if the path forms a right triangle.

  • For movements in a straight line with turns, sketch the path to visualize the final position68.

Example 3:

Nitara walks 1 km West, turns left, walks 1 km, turns left, walks 1 km, turns left, walks 450 m. How far is she from her starting point?
Solution:
She forms a square but walks only 450 m instead of 1 km on the last side.
Distance = 1 km - 450 m = 550 m from the starting point8.

C. Degree-Based Turns

  • Clockwise: Turning in the direction of a clock’s hands.

  • Anticlockwise: Turning opposite to the clock’s hands.

  • 90°, 180°, 270°, and 360° turns are common5.

Example 4:

If you are facing east and turn 135° clockwise, what direction are you facing?
Solution: 135° from East = South + 45° = South-West5.

4. Shadow-Based Questions

Shadow-based direction questions use the position of the sun and the resulting shadow to determine the direction a person is facing26.

A. Key Concepts

  • Sun rises in the East and sets in the West.

  • Morning: Shadows fall towards the West.

  • Evening: Shadows fall towards the East.

  • Noon: Shadows are shortest, generally fall to the North in India.

B. Common Patterns

Example 1:

One morning after sunrise, Amrit was standing facing a pole. The shadow of the pole was forming on the left side. Which direction was Amrit facing?
Solution:
Morning → shadow towards West.
If shadow is on left, Amrit is facing North2.

Example 2:

A person walks towards his house at 8:00 am and observes his shadow to his right. In which direction is he walking?
Solution:
8:00 am → Sun in East, shadow falls to the West. If shadow is to the right, person is facing South6.

Example 3:

In the evening, if a person’s shadow falls to his left, which direction is he facing?
Solution:
Evening → Sun in West, shadow towards East. If shadow is to the left, person is facing South.

5. Tips and Tricks

  • Always use the current facing direction as your reference when determining right/left turns.

  • Draw a simple diagram for complex paths.

  • For shadow questions, remember:

    • Morning: Shadow to the West

    • Evening: Shadow to the East

    • Noon: Shadow to the North (in India)

  • For degree-based turns, use a compass diagram.

  • Practice with actual sketches for multi-step problems.

6. Practice Examples

7. Conclusion

Direction sense and shadow-based questions require careful visualization and a systematic approach. Mastery comes from understanding the rules of movement, the effect of turns, and the behavior of shadows at different times of day. Always sketch the scenario for clarity and accuracy.

"Striking Black Gold: How the Andaman Oil Discovery Could Redefine India’s Energy Future"

Striking Black Gold: How the Andaman Oil Discovery Could Transform India's Energy and Economic Future India stands on the precipice of a potential energy revolution. With recent exploratory successes in the Andaman Sea, the discovery of massive oil reserves could mark a turning point in the nation’s energy independence and economic growth. In this comprehensive blog, we explore the timeline, policy evolution, global parallels, and the far-reaching implications of what many are calling India's "Black Gold" moment. Chronological Timeline of the Andaman Oil Discovery Early Exploration and Policy Shifts (2006–2016) For nearly a decade, India’s 3.5 million sq. km sedimentary basin region remained largely underexplored, with only 8% seeing oil and gas activity. Environmental restrictions and strategic concerns classified parts of the Andaman Sea as "no-go" areas, stalling any major offshore oil exploration efforts.
