Given:
40% girls and 92.5% girls pay fees
60% boys and 85% of boys pay fees
Calculation:
Let the total number of the students be 100
Number of girls = 40
Number of girls paid fees = 92.5% of 40 = 37
Number of boys = 60
Number of boys paid fees = 85% of 60 = 51
Number of student that didn't paid the fees = 100 - (37 + 51) = 12
And according to question,
12 = 180
⇒ 1 = 15
So the number of students = 15 × 100 = 1500
Number of students pay fees = 15 × 88 = 1320
∴ The number of students that gets scholarship = (1/2) × 1320 = 660
