Answer:

330

Step-by-step explanation:

Let total students = 100s

Boys = 60s

Girls = 40s

Boys getting fee waived off 15%

= (15/100)*60s = 9s

Girls getting fee waived off 7.5%

= (7.5/100)×40s = 3s

Total fee waiver 9s+ 3s = 12s

12s = 90

100s = (90/12)*100 = 750

Not getting fee concession = 750-90 =660

50% of them getting 50% concession = 660/2 = 330
