At the stadium, there were
111 as many boys as girls. After 82 boys came and 38 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?

| Before |
1 u |
11 u |
| Change |
+ 82 |
- 38 |
| After |
1 u + 82 |
11 u - 38 |
Number of children in the end is the same.
11 u - 38 = 1 u + 82
11 u - 1 u = 82 + 38
10 u = 120
1 u = 120 ÷ 10 = 12
Number of children in the end
= 2 x (1 u + 82)
= 2 u + 164
= 2 x 12 + 164
= 24 + 164
= 188
Answer(s): 188
