After |
4 u |
1 u |
4 u - 23 |
148 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 23
= 9 u - 23
9 u - 23 = 148
9 u = 148 + 23
9 u = 171
1 u = 171 ÷ 9 = 19
Number of mangosteens at first
= 4 u - 23 + 59
= 4 x 19 + 36
= 112
The number of mangosteens and kiwis at first is the same.
Number of kiwis sold
= 112 - 19
= 93
Answer(s): 93
