After |
3 u |
1 u |
3 u - 27 |
120 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 27
= 7 u - 27
7 u - 27 = 120
7 u = 120 + 27
7 u = 147
1 u = 147 ÷ 7 = 21
Number of grapefruits at first
= 3 u - 27 + 80
= 3 x 21 + 53
= 116
The number of grapefruits and peaches at first is the same.
Number of peaches sold
= 116 - 21
= 95
Answer(s): 95
