At a fruit stall, there were
18 as many mangosteens as kiwis. After 39 kiwis were sold, the number of mangosteens became
23 as many as the kiwis. How many fruits were at the fruit stall at first?
| |
Mangosteens |
Kiwis |
| Before |
1x2 =
2 u |
8x2 =
16 u |
| Change |
|
- 39 |
| 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 kiwis 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
