After |
2 u |
1 u |
2 u - 20 |
95 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 20
= 5 u - 20
5 u - 20 = 95
5 u = 95 + 20
5 u = 115
1 u = 115 ÷ 5 = 23
Number of persimmons at first
= 2 u - 20 + 59
= 2 x 23 + 39
= 85
The number of persimmons and mangosteens at first is the same.
Number of mangosteens sold
= 85 - 23
= 62
Answer(s): 62
