Percentage of students in various courses (A,B,C,D,E,F) and Percentage of girls out of these.
Total students:1200
(800 girls+400 boys)
Percentage in various courses
Total Girls: 800
Percentage of Girls in courses
For course E the number of girls is how much per cent more than the boys for course E ?
Solution
Course E:
Number of students = 12% of 1200 = 144
Number of girls = 14% of 800 = 112
Number of boys = 32
112 / 32 = 3.5
So, the number of girls is 3.5 - 1 = 2.5 times more than the number of boys = 250% more than the number of boys.
