At the funfair, there were 60% as many women as men and 20% more children than women. Given that there were 21 less women than children at the funfair, how many adults were there altogether?
| Women |
Men |
Children |
| 3x5 |
5x5 |
|
| 5x3 |
|
6x3 |
| 15 u |
25 u |
18 u |
60% =
60100 =
35Women : Men = 3 : 5
100% + 20% = 120%
120% =
120100 =
65 Women : Children = 5 : 6
The number of women is repeated. Make the number of women the same. LCM of 3 and 5 is 15.
Number of less women than children
= 18 u - 15 u
= 3 u
3 u = 21
1 u = 21 ÷ 3 = 7
Number of adults
= 15 u + 25 u
= 40 u
= 40 x 7
= 280
Answer(s): 280
