You would plug 15 and 21 into the equation provided so 15/21=x/100. You could then cross multiple giving you 21x=1500. You would divided by 21 on each side to isolate x. This should give you 71 and a super long decimal which is equal to 3/7. So the correct answer is 71(3/7)%. You could also just do 15 divided by 21 but that's to simple. Hope this helps!
In ratio 3:5
Lets take x1 as 3
Lets take x2 as 5
Lets take y1 as number of boys as y
Lets take y2 as number of girls as 60
x1:x2 :: y1:y2
Product of mean = Product of extremes
x2*y1 = x1 * y2
5*y = 3*60
5y = 180
y = 180/5 = 36
y2= 36
Therefore, the number of boys is 36 boys.
