A total of 257 adults and children went to a safari park. There were 23 more children than adults at the safari park. Given that the number of boys was 4 times the number of girls at the safari park, how many boys were at the safari park?

4 u |
1 u |

Number of girls = 1 u
Number of boys = 4 u
Number of children = 1 u + 4 u = 5 u
Number of adults = 5 u - 23
Total number of people
= 5 u + 5 u - 23
= 10 u - 23
10 u - 23 = 257
10 u = 257 + 23
10 u = 280
1 u = 280 ÷ 10 = 28
Number of boys
= 4 u
= 4 x 28
= 112
Answer(s): 112
