At a fruit stall, there were
14 as many mangosteens as starfruits. After 40 starfruits were sold, the number of mangosteens became
23 as many as the starfruits. How many fruits were at the fruit stall at first?
| |
Mangosteens |
Starfruits |
| Before |
1x2 =
2 u |
4x2 =
8 u |
| Change |
|
- 40 |
| After |
2x1 =
2 u |
3x1 =
3 u |
The number of mangosteens at first and in the end remains unchanged. Make the number of mangosteens the same. LCM of 1 and 2 is 2.
Number of starfruits sold
= 8 u - 3 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of fruits at first
= 2 u + 8 u
= 10 u
= 10 x 8
= 80
Answer(s): 80
