At the funfair, there were 40% as many women as men and 30% more children than women. Given that there were 9 less women than children at the funfair, how many adults were there altogether?
| Women |

| 2x5 |

| 10x1 |

13x1 |
| 10 u |
25 u |
13 u |
40% =
40100 =
25Women : Men = 2 : 5
100% + 30% = 130%
130% =
130100 =
1310 Women : Children = 10 : 13
The number of women is repeated. Make the number of women the same. LCM of 2 and 10 is 10.
Number of less women than children
= 13 u - 10 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Number of adults
= 10 u + 25 u
= 35 u
= 35 x 3
= 105
Answer(s): 105
