Show answer & explanation
Correct answer: C
Step-by-step solution:
Total number of students = 2200.
Combined percentage of class VII and VIII = 35% + 15% = 50%.
Combined percentage of class IX and X = 18% + 12% = 30%.
Difference in percentage = 50% − 30% = 20%.
Required number = 20% of 2200 = (20/100) × 2200 = 440.
Required difference = 440 students.
