A fruit stall had 4 times as many mangoes as starfruits. After 6 mangoes were added, the number of mangoes became 12 more than the number of starfruits. How many starfruits were there at the fruit stall at first?

Mangoes |
Starfruits |
Before |
4 u |
1 u |
Change |
+ 6 |
|
After |
4 u + 6 |
1 u |
If another 6 starfruits are added, the number of mangoes and starfruits will be the same.
4 u + 6 = 1 u + 12
4 u - 1 u = 12 - 6
3 u = 6
1 u = 6 ÷ 3 = 2
Number of starfruits at the fruit stall at first
= 1 u
= 2
Answer(s): 2
