1:2

2*3*5*7*11*13*17*19=9699690

8+1=9
9+2=11
11+3=14
14+4=18
18+5=23
and finally
23+6=29

the ratio is 4 : 3
so -> let’s suppose a case where multiplying both sides for the same number, the sum of the result will be 28 …

4 * 4 = 16
4 * 3 = 12
16 + 12 = 28

in 8 years they will be respectvely 24 and 20
which is the same as 6/5

1^1,2^2,3^3,4:^4,5^5,6^6
1,4,27,256,3125,46656

let no. of boys not participating be x
then the no. of girls not participating = x+5
no. of boys : girls participating = 3:2
given no.of boys participating = 15
therefore, the ratio is now 15:y(say)
then 3:2 = 15 : x
on solving 3/2 =15/y ie.., 3y =30 we get y =10
hence no. of girls participating =10
therefore total no of students paricipating = 15+10=25
total no of students in class =60 given
hence no. of students not participating = 60-25=35
therefore x+(x+5)=35
2x=30
x=15
therfore no of girls not participating =15+5=20
therefore total no of girls in class = no of girls
participating + no of girls not participating
=10+20
=30 is the answer

39/50
