At a fruit stall, there were
18 as many lemons as persimmons. After 39 persimmons were sold, the number of lemons became
23 as many as the persimmons. How many fruits were at the fruit stall at first?
|
Lemons |
Persimmons |
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 persimmons 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
