After |
2 u |
1 u |
2 u - 22 |
168 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 22
= 5 u - 22
5 u - 22 = 168
5 u = 168 + 22
5 u = 190
1 u = 190 ÷ 5 = 38
Number of chikoos at first
= 2 u - 22 + 40
= 2 x 38 + 18
= 94
The number of chikoos and grapefruits at first is the same.
Number of grapefruits sold
= 94 - 38
= 56
Answer(s): 56
