20 boys and girls sold tickets for a funfair. Each ticket was sold at $5.Each boy sold 5 tickets and each girl sold 3 tickets. The amount collected by the boys was $20 more than the amount collected by the girls. Find how many girls were there in the group

Answers (1)

Number of boys =20

Selling Price of each ticket =  $5

Amount collected by boys = $ 20 x 5 x 5 =$ 500

Assume number of girls = X

Amount collected by girls = $ X x 5 x 3 =$ 15X

Now 

15X + 20 = 500

X = 32
