A total of 346 adults and children went to a bird park. There were 30 more children than adults at the bird park. Given that the number of girls was 3 times the number of boys at the bird park, how many girls were at the bird park?

4 u - 30 |

3 u |
1 u |

Number of boys = 1 u
Number of girls = 3 u
Number of children = 1 u + 3 u = 4 u
Number of adults = 4 u - 30
Total number of people
= 4 u + 4 u - 30
= 8 u - 30
8 u - 30 = 346
8 u = 346 + 30
8 u = 376
1 u = 376 ÷ 8 = 47
Number of girls
= 3 u
= 3 x 47
= 141
Answer(s): 141
