Total number of students = 9800 Let total number of students enroll = 100y So, the total number of students enrol in college B =16y So, number of students in college B = (16y/100y) x 9800 = 1568 Ratio of the number of boys and girls in school = 5 : 9 Let the ratio is 5z : 9z Total number of students in college B = 5z + 9z = 14z Number of girls in college = (9z/14z) x 1568 = 1008 So, in college B 1008 girls enrolled. |
