Directions Sense formulas and a topic-wise mock test for logical reasoning placement exams like TCS NQT, Infosys, and Wipro. Revise, then practice.
Key Directions Sense Formulas
Direction Basics
Direction questions test your ability to understand spatial relationships and movement patterns.
- Cardinal Directions: North, South, East, West
- Intercardinal Directions: Northeast, Northwest, Southeast, Southwest
- Clockwise Rotation: Right turn increases direction by 90°
- Anticlockwise Rotation: Left turn decreases direction by 90°
Distance Calculation
Use these formulas for distance and displacement problems:
- Pythagoras Theorem: For right-angled triangles, a² + b² = c²
- Distance = √[(x₂-x₁)² + (y₂-y₁)²] for coordinate geometry
- Net Displacement = √(North-South)² + (East-West)²
- Average Speed = Total Distance / Total Time
Quick Solving Tips
Follow these steps for direction problems:
- Step 1: Draw a simple diagram with starting point
- Step 2: Mark each movement with direction and distance
- Step 3: Calculate final position using coordinates
- Step 4: Find shortest distance from final to starting point
Common Patterns
Recognize these common direction patterns:
- Pattern 1: Person moves in a square/rectangle pattern
- Pattern 2: Person moves in a circular pattern
- Pattern 3: Person moves in a zigzag pattern
- Pattern 4: Person moves in a spiral pattern
