Answer Posted / vidsln_2
let total no .of students participating sports=x
participating ratio =3:2
no of boys participating in the sports= 15
so, (3/5)*x=15
=25
no.of students not participating sports=60-25=35
v have, no.of non attending boys=y
no.of nn attending girls=y+5
so. y+y+5=35
y=15
no.of boys in the class=participating+ non participating
= 15+15=30
no.of girls in the class=total-no.of boys
=60-30
=30
