At a tourist attraction, there were
35 as many adults as children at first. After 46 adults left, there were 196 more children than adults remaining at a tourist attraction. How many adults were at the tourist attraction at first?
|
Adults |
Children |
Before |
3 u |
5 u |
Change |
- 46 |
|
After |
3 u - 46 |
5 u |
In the end, the number of children was 196 more than the number of adults. If another 196 adults entered the tourist attraction, the number of children and adults would be the same.
5 u = 3 u - 46 + 196
5 u - 3 u = 196 - 46
2 u = 150
1 u = 150 ÷ 2 = 75
Number of adults at first
= 3 u
= 3 x 75
= 225
Answer: 225
