perceptively simple DS

Admission tickets at a theater cost $10 for children and $15 for adults, what was the number of people that attended Tuesday's performance?

1) The ratio of the total proceeds from adult tickets to the total proceeds from children tickets at the show is 3/2

2) Total revenue from the sale of tickets at the show was $3,000

Question stem:
10$ for children
15$ for adults

Let x be the no of children
y be the adults

Stmt I

ratio of the total proceeds from adult tickets /ratio of the total proceeds from child tickets = 3/2

Do not the know the total sale of all proceeds
INSUFF


Stmt II

Total sale from all tickets= 3000

10x+15y = 3000

Many different values of x and y possible

INSUFF


Stmt I and II together

3000 split in to 3/2 ratio in only 1 way(1800 and 1200)

120 adults and 120 childrens attended the show.

Hope I dint miss something!
