Answer Posted / ahtesham
No. of boys participating in sports:B=15
therefore no. of girls participating in sports:G
as ratio is 3:2=B:G
3/2=B/G
G=(15*2)/3
G=10
No. of students not participating in sports=60-(15+10)=35
Let x be the no. of girls not participating in sports.
then x + (x-5)=35
x=15
total no. of girls in class=15+10=25
