Solutions:
1. Number of students enrolled in State C = 1200, Passed =
910
Required percentage = 910×100/1200 =
75.83%
2. In College B no of girls who successfully completed the
course = 1400 × 3/7 = 600
In College D no of girls who successfully completed the
course = 70 × 14× 2/5 = 392
Required % = 392/600 × 100 =
65.33%
3. No. of boys who passed from College F 1680 × 5/8 =
1050
No. of girls who passed from College E 840 × 7/12 =
