3 u |
1 u |
3 u - 27 |
85 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 27
= 7 u - 27
7 u - 27 = 85
7 u = 85 + 27
7 u = 112
1 u = 112 ÷ 7 = 16
Number of chikoos at first
= 3 u - 27 + 42
= 3 x 16 + 15
= 63
The number of chikoos and kiwis at first is the same.
Number of kiwis sold
= 63 - 16
= 47
Answer(s): 47
