At a fruit stall, there were
18 as many kiwis as mangosteens. After 40 mangosteens were sold, the number of kiwis became
34 as many as the mangosteens. How many fruits were at the fruit stall at first?
|
Kiwis |
Mangosteens |
Before |
1x3 = 3 u |
8x3 = 24 u |
Change |
|
- 40 |
After |
3x1 = 3 u |
4x1 = 4 u |
The number of kiwis at first and in the end remains unchanged. Make the number of kiwis the same. LCM of 1 and 3 is 3.
Number of mangosteens sold
= 24 u - 4 u
= 20 u
20 u = 40
1 u = 40 ÷ 20 = 2
Number of fruits at first
= 3 u + 24 u
= 27 u
= 27 x 2
= 54
Answer(s): 54
