Angular Component Calculation
View Complete Answer & Explanation
Question (English)
If Non-workers constitute 60.3% of the population, what will be their angular component in a pie diagram?
- 107°
- 180°
- 217° ✓ Correct
- 250°
Explanation:
Correct Answer Explanation
60.3% × 3.6° = 217.08° ≈ 217°.
Key Points:
- Formula: Angular component = Percentage × 3.6°.
- In the Indian population (2011) working status data: Non-workers = 73 crore out of 121 crore = 60.3%.
- Marginal Workers = 9.9% = 36°, Main Workers = 29.8% = 107°.
- Total of all angular components = 36° + 107° + 217° = 360°.
Why Other Options Are Wrong
- A. 107°: This is the angular component of Main Workers (29.8%).
- B. 180°: This would correspond to 50%, not 60.3%.
- D. 250°: This would correspond to about 69.4%, not 60.3%.
