Total number of students = 60000 Let the total number of students is 100%. Number of students in A = 18% Number of students failed in A = 24% of number of students enrolled in A. Number of students in C = 20% Number of students failed in C = 20% of the number of students enrolled in A |
Total number of students in A = (18/100) x 60000 = 10800 Total number of students failed in A = (24/100) x 10800 = 2592 Total number of students in C = (20/100) x 60000 = 12000 Total number of students failed in C = (20/100) x 12000 = 2400 Total number of students failed in A and B = 2592 + 2400 = 4992 |
