At a stadium, there were
35 as many adults as children at first. After 52 adults left, there were 190 more children than adults remaining at a stadium. How many children were at the stadium?
|
Adults |
Children |
Before |
3 u |
5 u |
Change |
- 52 |
|
After |
3 u - 52 |
5 u |
In the end, the number of children was 190 more than the number of adults. If another 190 adults entered the stadium, the number of children and adults would be the same.
5 u = 3 u - 52 + 190
5 u - 3 u = 190 - 52
2 u = 138
1 u = 138 ÷ 2 = 69
Number of children at first
= 5 u
= 5 x 69
= 345
Answer: 345
