After |
4 u |
1 u |
4 u - 26 |
163 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 26
= 9 u - 26
9 u - 26 = 163
9 u = 163 + 26
9 u = 189
1 u = 189 ÷ 9 = 21
Number of kiwis at first
= 4 u - 26 + 76
= 4 x 21 + 50
= 134
The number of kiwis and grapefruits at first is the same.
Number of grapefruits sold
= 134 - 21
= 113
Answer(s): 113
