3 u |
1 u |
3 u - 23 |
82 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 23
= 7 u - 23
7 u - 23 = 82
7 u = 82 + 23
7 u = 105
1 u = 105 ÷ 7 = 15
Number of peaches at first
= 3 u - 23 + 55
= 3 x 15 + 32
= 77
The number of peaches and starfruits at first is the same.
Number of starfruits sold
= 77 - 15
= 62
Answer(s): 62
