At the theme park, there were 60% as many boys as girls and 10% more adults than boys. Given that there were 24 more adults than boys at the theme park, how many children were there altogether?

35Boys : Girls = 3 : 5
100% + 10% = 110%
110% =
110100 =
1110 Boys : Adults = 10 : 11
The number of boys is repeated. Make the number of boys the same. LCM of 3 and 10 is 30.
Number of more adults than boys
= 33 u - 30 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Number of children
= 30 u + 50 u
= 80 u
= 80 x 8
= 640
Answer(s): 640
