At a fruit stall, there were
13 as many starfruits as passion fruits. After 39 passion fruits were sold, the number of starfruits became
23 as many as the passion fruits. How many fruits were at the fruit stall at first?
|
Starfruits |
Passion Fruits |
Before |
1x2 = 2 u |
3x2 = 6 u |
Change |
|
- 39 |
After |
2x1 = 2 u |
3x1 = 3 u |
The number of starfruits at first and in the end remains unchanged. Make the number of starfruits the same. LCM of 1 and 2 is 2.
Number of passion fruits sold
= 6 u - 3 u
= 3 u
3 u = 39
1 u = 39 ÷ 3 = 13
Number of fruits at first
= 2 u + 6 u
= 8 u
= 8 x 13
= 104
Answer(s): 104
