Pomegranates |
Avocados |
| Before |
3 u |
1 u |
| Change |
+ 30 |
+ 74 |
| After |
3 u + 30 |
1 u + 74 |
The number of pomegranates and avocados is the same in the end.
3 u + 30 = 1 u + 74
3 u - 1 u = 74 - 30
2 u = 44
1 u = 44 ÷ 2 = 22
Number of pomegranates at first
= 3 u
= 3 x 22
= 66
Answer(s): 66
