At a fruit stall, there were
13 as many passion fruits as oranges. After 10 oranges were sold, the number of passion fruits became
34 as many as the oranges. How many fruits were at the fruit stall at first?
|
Passion Fruits |
Oranges |
Before |
1x3 = 3 u |
3x3 = 9 u |
Change |
|
- 10 |
After |
3x1 = 3 u |
4x1 = 4 u |
The number of passion fruits at first and in the end remains unchanged. Make the number of passion fruits the same. LCM of 1 and 3 is 3.
Number of oranges sold
= 9 u - 4 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Number of fruits at first
= 3 u + 9 u
= 12 u
= 12 x 2
= 24
Answer(s): 24
