Correct answer: C
To find the average percentage of passed students across all schools, we need to calculate the passing percentage for each school individually and then find their overall average.
Step-by-Step Analysis
Extract Data from Graph:
School A: Appeared = 3000, Qualified = 1750.
Percentage = (1750 / 3000) * 100 = 58.33%
School B: Appeared = 2250, Qualified = 1250.
Percentage = (1250 / 2250) * 100 = 55.56%
School C: Appeared = 3250, Qualified = 2250.
Percentage = (2250 / 3250) * 100 = 69.23%
School D: Appeared = 2500, Qualified = 2000.
Percentage = (2000 / 2500) * 100 = 80.00%
School E: Appeared = 3000, Qualified = 2000.
Percentage = (2000 / 3000) * 100 = 66.67%
Calculate the Average:
Sum of percentages = 58.33 + 55.56 + 69.23 + 80.00 + 66.67 = 329.79%
Average percentage = 329.79 / 5 = 65.958%
This value is approximately 66%.
