Introduction
Direction-based puzzles are a key part of intelligence testing. These problems test your ability to visualize space and track movement. By understanding the 8 main directions and how turns work, you can solve any navigation problem easily. Remember, in most maps and diagrams, North is always at the top!
Explanation Step by Step
To master direction problems, follow these logic points:
- There are 4 main directions: North, South, East, and West.
- There are 4 sub-directions: North-East, North-West, South-East, and South-West.
- A Right Turn means moving in a Clockwise direction.
- A Left Turn means moving in a Counter-Clockwise direction.
- Sun rises in the East and sets in the West.
Sub-topics
Movement and Turns
This sub-topic focuses on tracking how many times a person turns while traveling from point A to point B.
Examples
Example 1
Tricks and Shortcuts
Always draw a small "+" sign on your paper to mark North, South, East, and West before starting the problem.
Common Mistakes
Confusing Left and Right: Remember that if you are facing South, your "Left" is actually towards the East!
Practice Questions
Easy Questions
- If you are facing the rising sun, which direction is behind you?
- A person walks 5 km North and then turns Right. Which direction are they facing?
- Which direction lies exactly between South and West?
Medium Questions
- Rohan travels 3 km East, turns Left and walks 4 km. How far is he from the starting point?
- A girl is facing North-West. she turns 90 degrees clockwise. Which direction is she facing now?
- If North becomes South-East, what will West become?
Hard Questions
- A man starts walking towards the South. After 2 km, he turns left, then right, then another left. In which direction is he walking now?
- At 6:00 PM, the hour hand of a clock points North. In which direction does the minute hand point?
- Starting from a point, Meena walked 10 meters West, then turned left and walked 10 meters. She then turned left again and walked 10 meters. How far and in what direction is she from the start?
Revision Summary
Use the 8-direction map, associate right turns with clockwise motion, and always identify your starting orientation carefully.
