At the stadium, there were
58 as many boys as girls. After 44 boys came and 25 girls left the stadium, there was an equal number of boys and girls who remained at the stadium. How many children were at the stadium in the end?

8 u |
Change |
+ 44 |
- 25 |
After |
5 u + 44 |
8 u - 25 |
Number of children in the end is the same.
8 u - 25 = 5 u + 44
8 u - 5 u = 44 + 25
3 u = 69
1 u = 69 ÷ 3 = 23
Number of children in the end
= 2 x (5 u + 44)
= 10 u + 88
= 10 x 23 + 88
= 230 + 88
= 318
Answer(s): 318
