At a park, there were
27 as many adults as children at first. After 24 adults left, there were 184 more children than adults remaining at a park. How many adults were at the park at first?
| |
Adults |
Children |
| Before |
2 u |
7 u |
| Change |
- 24 |
|
| After |
2 u - 24 |
7 u |
In the end, the number of children was 184 more than the number of adults. If another 184 adults entered the park, the number of children and adults would be the same.
7 u = 2 u - 24 + 184
7 u - 2 u = 184 - 24
5 u = 160
1 u = 160 ÷ 5 = 32
Number of adults at first
= 2 u
= 2 x 32
= 64
Answer: 64
