A fruit stall had 5 times as many dragonfruits as mangoes. After 5 dragonfruits were added, the number of dragonfruits became 25 more than the number of mangoes. How many mangoes were there at the fruit stall at first?
| |
Dragonfruits |
Mangoes |
| Before |
5 u |
1 u |
| Change |
+ 5 |
|
| After |
5 u + 5 |
1 u |
If another 5 mangoes are added, the number of dragonfruits and mangoes will be the same.
5 u + 5 = 1 u + 25
5 u - 1 u = 25 - 5
4 u = 20
1 u = 20 ÷ 4 = 5
Number of mangoes at the fruit stall at first
= 1 u
= 5
Answer(s): 5
