At a fruit stall, there were
14 as many oranges as mangosteens. After 50 mangosteens were sold, the number of oranges became
23 as many as the mangosteens. How many fruits were at the fruit stall at first?
| |
Oranges |
Mangosteens |
| Before |
1x2 =
2 u |
4x2 =
8 u |
| Change |
|
- 50 |
| After |
2x1 =
2 u |
3x1 =
3 u |
The number of oranges at first and in the end remains unchanged. Make the number of oranges the same. LCM of 1 and 2 is 2.
Number of mangosteens sold
= 8 u - 3 u
= 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Number of fruits at first
= 2 u + 8 u
= 10 u
= 10 x 10
= 100
Answer(s): 100
