Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 26250
The total number of students in all grades combined = 20,000 + 15,000 + 12,000 + 22,000 + 8,000 + 18,000 + 14,000 + 9,000 + 10,000 + 12,000 140,000
The number of students in school D = (25 / 100) × 140,000 = 35,000
The number of boys studying in school D = (3 / 4) × 35,000 = 26,250
