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
a) how many girls were there in the group
b) how many tickets were sold altogether?
No Of Boys = 20
Let No Of Girls = x
No. Of Tickets sold by One Boy = 5
Therefore Number of tickets Sold by 20 Boys = 5*20
Cost of one Ticket = $5
therefore Cost of 100 Tickets = $5*100
No. Of tickets Sold by One Girl = 3
Therefore , No of tickets Sold By x Girls = 3*x
Therefore Cost of 3x tickets = $5*3x
According to Problem ,
$15x = $500 - $20
Hence The Number of Girls is 32 .
b) therefore total Number of Tickets sold = 100 + 3x
= 100 + 3*32
= 100 + 96
Hope This Helps You!!!
