After |
2 u |
1 u |
2 u - 29 |
81 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 29
= 5 u - 29
5 u - 29 = 81
5 u = 81 + 29
5 u = 110
1 u = 110 ÷ 5 = 22
Number of pomegranates at first
= 2 u - 29 + 51
= 2 x 22 + 22
= 66
The number of pomegranates and peaches at first is the same.
Number of peaches sold
= 66 - 22
= 44
Answer(s): 44
