A total of 348 adults and children went to a tourist attraction. There were 42 more children than adults at the tourist attraction. Given that the number of girls was 4 times the number of boys at the tourist attraction, how many girls were at the tourist attraction?
| Adults |

4 u |
1 u |

Number of boys = 1 u
Number of girls = 4 u
Number of children = 1 u + 4 u = 5 u
Number of adults = 5 u - 42
Total number of people
= 5 u + 5 u - 42
= 10 u - 42
10 u - 42 = 348
10 u = 348 + 42
10 u = 390
1 u = 390 ÷ 10 = 39
Number of girls
= 4 u
= 4 x 39
= 156
Answer(s): 156
