At a fruit stall, there were
13 as many starfruits as pears. After 36 pears were sold, the number of starfruits became
23 as many as the pears. How many fruits were at the fruit stall at first?
|
Starfruits |
Pears |
Before |
1x2 = 2 u |
3x2 = 6 u |
Change |
|
- 36 |
After |
2x1 = 2 u |
3x1 = 3 u |
The number of starfruits at first and in the end remains unchanged. Make the number of starfruits the same. LCM of 1 and 2 is 2.
Number of pears sold
= 6 u - 3 u
= 3 u
3 u = 36
1 u = 36 ÷ 3 = 12
Number of fruits at first
= 2 u + 6 u
= 8 u
= 8 x 12
= 96
Answer(s): 96
