After |
2 u |
1 u |
2 u - 30 |
195 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 30
= 5 u - 30
5 u - 30 = 195
5 u = 195 + 30
5 u = 225
1 u = 225 ÷ 5 = 45
Number of mangoes at first
= 2 u - 30 + 45
= 2 x 45 + 15
= 105
The number of mangoes and starfruits at first is the same.
Number of starfruits sold
= 105 - 45
= 60
Answer(s): 60
