2 u |
1 u |
2 u - 23 |
77 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 23
= 5 u - 23
5 u - 23 = 77
5 u = 77 + 23
5 u = 100
1 u = 100 ÷ 5 = 20
Number of pomegranates at first
= 2 u - 23 + 41
= 2 x 20 + 18
= 58
The number of pomegranates and kiwis at first is the same.
Number of kiwis sold
= 58 - 20
= 38
Answer(s): 38
