4 u |
1 u |
4 u - 20 |
196 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 20
= 9 u - 20
9 u - 20 = 196
9 u = 196 + 20
9 u = 216
1 u = 216 ÷ 9 = 24
Number of persimmons at first
= 4 u - 20 + 70
= 4 x 24 + 50
= 146
The number of persimmons and lemons at first is the same.
Number of lemons sold
= 146 - 24
= 122
Answer(s): 122
