A fruit stall had 3 times as many peaches as mangosteens. After 6 peaches were added, the number of peaches became 10 more than the number of mangosteens. How many mangosteens were there at the fruit stall at first?
|
Peaches |
Mangosteens |
Before |
3 u |
1 u |
Change |
+ 6 |
|
After |
3 u + 6 |
1 u |
If another 6 mangosteens are added, the number of peaches and mangosteens will be the same.
3 u + 6 = 1 u + 10
3 u - 1 u = 10 - 6
2 u = 4
1 u = 4 ÷ 2 = 2
Number of mangosteens at the fruit stall at first
= 1 u
= 2
Answer(s): 2
