At a fruit stall, there were
18 as many lemons as kiwis. After 39 kiwis were sold, the number of lemons became
23 as many as the kiwis. How many fruits were at the fruit stall at first?
| |
Lemons |
Kiwis |
| Before |
1x2 =
2 u |
8x2 =
16 u |
| Change |
|
- 39 |
| After |
2x1 =
2 u |
3x1 =
3 u |
The number of lemons at first and in the end remains unchanged. Make the number of lemons the same. LCM of 1 and 2 is 2.
Number of kiwis sold
= 16 u - 3 u
= 13 u
13 u = 39
1 u = 39 ÷ 13 = 3
Number of fruits at first
= 2 u + 16 u
= 18 u
= 18 x 3
= 54
Answer(s): 54
