At the tourist attraction, there were
58 as many girls as boys. After 46 girls came and 29 boys left the tourist attraction, there was an equal number of girls and boys who remained at the tourist attraction. How many children were at the tourist attraction in the end?

Girls |
Boys |
| Before |
5 u |
8 u |
| Change |
+ 46 |
- 29 |
| After |
5 u + 46 |
8 u - 29 |
Number of children in the end is the same.
8 u - 29 = 5 u + 46
8 u - 5 u = 46 + 29
3 u = 75
1 u = 75 ÷ 3 = 25
Number of children in the end
= 2 x (5 u + 46)
= 10 u + 92
= 10 x 25 + 92
= 250 + 92
= 342
Answer(s): 342
