Clockwise Anticlockwise

Clockwise/Anticlockwise problems involve turning a specified number of degrees (90°, 180°, 270°, 360°) in a given rotational direction. Each 90° turn corresponds to moving to the next cardinal direction clockwise (right) or anticlockwise (left). These problems test understanding of degree-based rotations and their effect on facing direction.

Introduction to Clockwise Anticlockwise

Clockwise/Anticlockwise problems involve turning a specified number of degrees (90°, 180°, 270°, 360°) in a given rotational direction. Each 90° turn corresponds to moving to the next cardinal direction clockwise (right) or anticlockwise (left). These problems test understanding of degree-based rotations and their effect on facing direction.

Prerequisites

Understanding of degrees in a circle (360°) Clockwise = right turn, anticlockwise = left turn 90° = 1 direction step 180° = opposite direction 270° = 3 steps clockwise or 1 step anticlockwise 360° = full circle (same direction)
Why This Matters: Clockwise/Anticlockwise problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test precise angular rotation concepts.

How to Solve Clockwise Anticlockwise Problems

1

Step 1: Identify starting direction

2

Step 2: Identify turn direction (clockwise or anticlockwise) and degrees

3

Step 3: Convert degrees to steps: steps = degrees ÷ 90

4

Step 4: For clockwise: move steps forward in N→E→S→W→N cycle

5

Step 5: For anticlockwise: move steps backward in the cycle

6

Step 6: Apply modulo 4 to handle multiple full rotations

7

Step 7: The final direction is the result after moving steps

Pro Strategy: Convert degrees to steps by dividing by 90. Reduce steps modulo 4 (since 4 steps = 360° = full circle). Apply steps in clockwise or anticlockwise direction from starting point.

Example Problem

Example: A person facing North turns 270° clockwise. Which direction is he now facing? Solution: Step 1: Start = North Step 2: 270° clockwise Step 3: Steps = 270 ÷ 90 = 3 steps clockwise Step 4: From North: 1 step → East, 2 steps → South, 3 steps → West Step 5: Final direction = West Answer: West Alternative: 270° clockwise = 90° anticlockwise = West

Pro Tips & Tricks

  • 90° = 1 step, 180° = 2 steps, 270° = 3 steps, 360° = 4 steps = 0 steps
  • Clockwise = forward in N→E→S→W→N cycle
  • Anticlockwise = backward in N→E→S→W→N cycle
  • 270° clockwise = 90° anticlockwise (net effect same)
  • 180° any direction = opposite direction
  • 360° any direction = same direction

Shortcut Methods to Solve Faster

Steps = degrees ÷ 90
Final index = (start_index + steps × direction) mod 4 (clockwise = +1, anticlockwise = -1)
N=0, E=1, S=2, W=3
270° clockwise = 3 steps = -1 step anticlockwise
If steps mod 4 = 0 → same direction

Common Mistakes to Avoid

Using 90° = 1 step but forgetting modulo 4 for multiple rotations
Confusing clockwise with anticlockwise direction
Not reducing degrees modulo 360 before calculating
Mixing step count with degree measure in final answer
