What is the difference between the number of students passed from cities C and E combined, and the number of students passed from cities A and B combined?
Answer: B
Percentage for C and E = 25% + 25% = 50%.
Percentage for A and B = 12% + 18% = 30%.
The difference in percentage = 50% - 30% = 20%.
The difference in number of students = 20% of 1400 = 0.20 * 1400 = 280.
