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
