At a fruit stall, there were
15 as many lemons as apples. After 28 apples were sold, the number of lemons became
23 as many as the apples. How many fruits were at the fruit stall at first?
|
Lemons |
Apples |
Before |
1x2 = 2 u |
5x2 = 10 u |
Change |
|
- 28 |
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 apples sold
= 10 u - 3 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Number of fruits at first
= 2 u + 10 u
= 12 u
= 12 x 4
= 48
Answer(s): 48
