Correct Answer Explanation
Each percentage figure of every component is multiplied by 3.6° to convert it into an angular component.
Key Points:
- Total degrees in a circle = 360°.
- Total percentage = 100%.
- Each 1% = 360° ÷ 100 = 3.6°.
- Example: 60.3% becomes 60.3 × 3.6° = 217° (angular component for Non-workers in India).
- This formula is essential for constructing pie charts in exams.
Why Other Options Are Wrong
- A. 1.8°: Incorrect calculation.
- B. 2.6°: No mathematical basis for this value.
- D. 4.2°: This would give total exceeding 360°.
