A fruit stall had 4 times as many peaches as grapefruits. After 8 peaches were added, the number of peaches became 11 more than the number of grapefruits. How many grapefruits were there at the fruit stall at first?

Peaches |
Grapefruits |
| Before |
4 u |
1 u |
| Change |
+ 8 |
|
| After |
4 u + 8 |
1 u |
If another 8 grapefruits are added, the number of peaches and grapefruits will be the same.
4 u + 8 = 1 u + 11
4 u - 1 u = 11 - 8
3 u = 3
1 u = 3 ÷ 3 = 1
Number of grapefruits at the fruit stall at first
= 1 u
= 1
Answer(s): 1
