After |
2 u |
1 u |
2 u - 36 |
194 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 36
= 5 u - 36
5 u - 36 = 194
5 u = 194 + 36
5 u = 230
1 u = 230 ÷ 5 = 46
Number of starfruits at first
= 2 u - 36 + 40
= 2 x 46 + 4
= 96
The number of starfruits and kiwis at first is the same.
Number of kiwis sold
= 96 - 46
= 50
Answer(s): 50
