Question

In a group of 75 campers, boys outnumber girls by a 3:2 ratio. How many more girl campers would have to join the group to give it a 1:1 ratio of boys to girls? 6 9 10 12 15

Answer 1

Total=75 campers
Ratio= 3:2


Total ratio=3+2
=5
Number of boys=3/5of 75
=45 boys

Girls=2/5 of75
=30

45-x=30+x2
45-30=x+x
15. =2x
7.5=x
x=7.5



45-7.5:30+7.5
37.5:37.5
1:1
Therefore the answer is not among the possible answers
