After |
2 u |
1 u |
2 u - 29 |
146 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 29
= 5 u - 29
5 u - 29 = 146
5 u = 146 + 29
5 u = 175
1 u = 175 ÷ 5 = 35
Number of chikoos at first
= 2 u - 29 + 71
= 2 x 35 + 42
= 112
The number of chikoos and mangosteens at first is the same.
Number of mangosteens sold
= 112 - 35
= 77
Answer(s): 77
