A total of 336 adults and children went to a bird park. There were 32 more children than adults at the bird park. Given that the number of boys was 3 times the number of girls at the bird park, how many boys were at the bird park?
| Adults |
Children |
Total |
| 4 u - 32 |
4 u |
336 |
| |
Boys |
Girls |

3 u |
1 u |

Number of girls = 1 u
Number of boys = 3 u
Number of children = 1 u + 3 u = 4 u
Number of adults = 4 u - 32
Total number of people
= 4 u + 4 u - 32
= 8 u - 32
8 u - 32 = 336
8 u = 336 + 32
8 u = 368
1 u = 368 ÷ 8 = 46
Number of boys
= 3 u
= 3 x 46
= 138
Answer(s): 138
