At a fruit stall, there were
13 as many mangosteens as passion fruits. After 30 passion fruits were sold, the number of mangosteens became
34 as many as the passion fruits. How many fruits were at the fruit stall at first?
| |
Mangosteens |
Passion Fruits |
| Before |
1x3 =
3 u |
3x3 =
9 u |
| Change |
|
- 30 |
| After |
3x1 =
3 u |
4x1 =
4 u |
The number of mangosteens at first and in the end remains unchanged. Make the number of mangosteens the same. LCM of 1 and 3 is 3.
Number of passion fruits sold
= 9 u - 4 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Number of fruits at first
= 3 u + 9 u
= 12 u
= 12 x 6
= 72
Answer(s): 72
