At a fruit stall, there were
13 as many lemons as passion fruits. After 30 passion fruits were sold, the number of lemons became
34 as many as the passion fruits. How many fruits were at the fruit stall at first?

Lemons |
Passion Fruits |
| Before |
1x3 =
3 u |
3x3 =
9 u |
| Change |
|
- 30 |
| After |
3x1 =
3 u |
4x1 =
4 u |
The number of lemons at first and in the end remains unchanged. Make the number of lemons 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
