At a fruit stall, there were
13 as many apples as mangosteens. After 45 mangosteens were sold, the number of apples became
34 as many as the mangosteens. How many fruits were at the fruit stall at first?
|
Apples |
Mangosteens |
Before |
1x3 = 3 u |
3x3 = 9 u |
Change |
|
- 45 |
After |
3x1 = 3 u |
4x1 = 4 u |
The number of apples at first and in the end remains unchanged. Make the number of apples the same. LCM of 1 and 3 is 3.
Number of mangosteens sold
= 9 u - 4 u
= 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Number of fruits at first
= 3 u + 9 u
= 12 u
= 12 x 9
= 108
Answer(s): 108
