A total of 240 children and adults went to a concert hall. There were 30 more adults than children at the concert hall. Given that the number of women was 4 times the number of men at the concert hall, how many women were at the concert hall?
| Children |

| 5 u - 30 |

4 u |
1 u |

Number of men = 1 u
Number of women = 4 u
Number of adults = 1 u + 4 u = 5 u
Number of children = 5 u - 30
Total number of people
= 5 u + 5 u - 30
= 10 u - 30
10 u - 30 = 240
10 u = 240 + 30
10 u = 270
1 u = 270 ÷ 10 = 27
Number of women
= 4 u
= 4 x 27
= 108
Answer(s): 108
