At a fruit stall, there were
13 as many oranges as starfruits. After 27 starfruits were sold, the number of oranges became
23 as many as the starfruits. How many fruits were at the fruit stall at first?
| |
Oranges |
Starfruits |
| Before |
1x2 =
2 u |
3x2 =
6 u |
| Change |
|
- 27 |
| After |
2x1 =
2 u |
3x1 =
3 u |
The number of oranges at first and in the end remains unchanged. Make the number of oranges the same. LCM of 1 and 2 is 2.
Number of starfruits sold
= 6 u - 3 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Number of fruits at first
= 2 u + 6 u
= 8 u
= 8 x 9
= 72
Answer(s): 72
