2 u |
1 u |
2 u - 17 |
188 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 17
= 5 u - 17
5 u - 17 = 188
5 u = 188 + 17
5 u = 205
1 u = 205 ÷ 5 = 41
Number of grapefruits at first
= 2 u - 17 + 62
= 2 x 41 + 45
= 127
The number of grapefruits and guavas at first is the same.
Number of guavas sold
= 127 - 41
= 86
Answer(s): 86
