After |
2 u |
1 u |
2 u - 21 |
104 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 21
= 5 u - 21
5 u - 21 = 104
5 u = 104 + 21
5 u = 125
1 u = 125 ÷ 5 = 25
Number of starfruits at first
= 2 u - 21 + 60
= 2 x 25 + 39
= 89
The number of starfruits and chikoos at first is the same.
Number of chikoos sold
= 89 - 25
= 64
Answer(s): 64
