After |
4 u |
1 u |
4 u - 17 |
118 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 17
= 9 u - 17
9 u - 17 = 118
9 u = 118 + 17
9 u = 135
1 u = 135 ÷ 9 = 15
Number of chikoos at first
= 4 u - 17 + 58
= 4 x 15 + 41
= 101
The number of chikoos and grapefruits at first is the same.
Number of grapefruits sold
= 101 - 15
= 86
Answer(s): 86
