Show answer & explanation
Correct answer: C
For each section, first find the total number of students, then calculate (failed in both / total) x 100. A: 12/(12+13+15+20) = 12/60 = 20%. B: 15/(15+15+18+22) = 15/70 = 21.43%. C: 18/(18+12+22+18) = 18/70 = 25.71%. D: 10/(10+15+14+21) = 10/60 = 16.67%. The highest percentage is for section C.
