Question

The pie-chart shows the percentage-wise distribution of the number of students in five different schools P, Q, R. S and T. The total number of students in all five schools together is 10,500 The difference between the central angles corresponding to schools T and R is

• A. 43.2°
• B. 151.2°
• C. 54°
• D. 36°

Answer 1

Answer:

A. 43.2°

• Central Angle = (Percentage / 100) × 360°

  • Since the difference in percentages between School T and School R is 12%, we can directly find the difference in their central angles

  • Difference in Central Angles = (Percentage Difference / 100) × 360°

  • Difference in Central Angles = (12 / 100) × 360°

  • Difference in Central Angles = 0.12 × 360° = 43.2°
