At a fun fair, 2/5 of the number of boy is equal to 1/3 of the number of girls. The number of adults is 1/4 of the total number of children. Each boy spent $3, each girl spent $5 and each adult spent $8. The total amount of money spent by the girls was $1600 more than the total amount of money spent by the adults. What was the total number of adults at the fun fair?

2/5B ==1/3G,
1/4(B + G)==A,
5G  - 8A ==1,600, solve for A, B, G


A==550 - adults at the fair.
B==1,000 - boys at the fair.
G==1,200 - girls at the fair.
