The monthly budget of Mr. Iyer's household is ₹1,80,000, of which ₹54,000 is spent on education. In a pie chart of the budget, the angle at the centre for education will be:
The central angle is 108°. Education forms 54,000 out of 1,80,000, which is 30% of the budget, and 30% of the full circle of 360° equals 108°. A pie chart angle is always the component's share multiplied by 360 degrees.
- A54°
- B90°
- C108°Correct
- D120°
Explanation
Share of education = 54,000 / 1,80,000 = 0.30. Angle = 0.30 × 360° = 108°. Option A takes the rupee thousands as degrees, and option B corresponds to a 25% share.
