A fruit stall had 3 times as many peaches as pears. After 12 peaches were added, the number of peaches became 18 more than the number of pears. How many pears were there at the fruit stall at first?

Peaches |
Pears |
| Before |
3 u |
1 u |
| Change |
+ 12 |
|
| After |
3 u + 12 |
1 u |
If another 12 pears are added, the number of peaches and pears will be the same.
3 u + 12 = 1 u + 18
3 u - 1 u = 18 - 12
2 u = 6
1 u = 6 ÷ 2 = 3
Number of pears at the fruit stall at first
= 1 u
= 3
Answer(s): 3
