At a museum, there were
35 as many adults as children at first. After 33 adults left, there were 193 more children than adults remaining at a museum. How many children were at the museum?
|
Adults |
Children |
Before |
3 u |
5 u |
Change |
- 33 |
|
After |
3 u - 33 |
5 u |
In the end, the number of children was 193 more than the number of adults. If another 193 adults entered the museum, the number of children and adults would be the same.
5 u = 3 u - 33 + 193
5 u - 3 u = 193 - 33
2 u = 160
1 u = 160 ÷ 2 = 80
Number of children at first
= 5 u
= 5 x 80
= 400
Answer: 400
