4 u |
1 u |
4 u - 30 |
195 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 30
= 9 u - 30
9 u - 30 = 195
9 u = 195 + 30
9 u = 225
1 u = 225 ÷ 9 = 25
Number of persimmons at first
= 4 u - 30 + 51
= 4 x 25 + 21
= 121
The number of persimmons and starfruits at first is the same.
Number of starfruits sold
= 121 - 25
= 96
Answer(s): 96
