After |
2 u |
1 u |
2 u - 35 |
75 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 35
= 5 u - 35
5 u - 35 = 75
5 u = 75 + 35
5 u = 110
1 u = 110 ÷ 5 = 22
Number of lemons at first
= 2 u - 35 + 53
= 2 x 22 + 18
= 62
The number of lemons and mangosteens at first is the same.
Number of mangosteens sold
= 62 - 22
= 40
Answer(s): 40
