GIVEN:
Number of boys appearing for the exam = 75
FORMULA USED:
Percentage of girls who passed the exam = (Number of girls passing the exam/Number of girls appearing the exam) × 100
CALCULATION:
Number of boys passing the exam = (80/100) × 75 = 60
Total Number of students in the school appearing for the exam = 145
Number of girls appearing for the exam = 145 – 75 = 70
Number of girls passing the exam = 60 – 2 = 58
Percentage of girls who passed the exam = (58/70) × 100 = 82.85%

- Total number of students who appeared for the exam = 145
- Number of boys who appeared for the exam = 75

To find:
- Percentage of girls who passed the exam

Approach:
