At a fruit stall, there were
15 as many mangosteens as oranges. After 14 oranges were sold, the number of mangosteens became
23 as many as the oranges. How many fruits were at the fruit stall at first?
|
Mangosteens |
Oranges |
Before |
1x2 = 2 u |
5x2 = 10 u |
Change |
|
- 14 |
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 oranges sold
= 10 u - 3 u
= 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Number of fruits at first
= 2 u + 10 u
= 12 u
= 12 x 2
= 24
Answer(s): 24
