At the concert hall, there were
17 as many boys as girls. After 88 boys came and 26 girls left the concert hall, there was an equal number of boys and girls who remained at the concert hall. How many children were at the concert hall in the end?

Before |
1 u |
7 u |
Change |
+ 88 |
- 26 |
After |
1 u + 88 |
7 u - 26 |
Number of children in the end is the same.
7 u - 26 = 1 u + 88
7 u - 1 u = 88 + 26
6 u = 114
1 u = 114 ÷ 6 = 19
Number of children in the end
= 2 x (1 u + 88)
= 2 u + 176
= 2 x 19 + 176
= 38 + 176
= 214
Answer(s): 214
