At the funfair, there were 60% as many men as women and 40% more children than men. Given that there were 24 more children than men at the funfair, how many adults were there altogether?
| Men |
Women |
Children |
| 3x5 |
5x5 |
|
| 5x3 |
|
7x3 |
| 15 u |
25 u |
21 u |
60% =
60100 =
35Men : Women = 3 : 5
100% + 40% = 140%
140% =
140100 =
75 Men : Children = 5 : 7
The number of men is repeated. Make the number of men the same. LCM of 3 and 5 is 15.
Number of more children than men
= 21 u - 15 u
= 6 u
6 u = 24
1 u = 24 ÷ 6 = 4
Number of adults
= 15 u + 25 u
= 40 u
= 40 x 4
= 160
Answer(s): 160
