3 u |
1 u |
3 u - 32 |
80 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 32
= 7 u - 32
7 u - 32 = 80
7 u = 80 + 32
7 u = 112
1 u = 112 ÷ 7 = 16
Number of mangoes at first
= 3 u - 32 + 79
= 3 x 16 + 47
= 95
The number of mangoes and kiwis at first is the same.
Number of kiwis sold
= 95 - 16
= 79
Answer(s): 79
