Question

Out of the original girls and boys at a carnival party 40% of the girls and 10% of the boys left early, 3/4 of them decided to hang out and enjoy the festivities. There were 18 more boys than girls in the party. How many girls were there to begin with?

Answer 1

Answer:

Step-by-step explanation:

Let the girls number be =x

So that the num of boys =(x + 160)

45/100(x + 160)=55/100*x

45x +7200 =55x

10x= 7200

X = 7200/10

=720
