A store owner had the same number of pears, kiwis and mangoes at first. After 55 mangoes, some pears and kiwis were sold, there were 106 fruits left. There were four times as many pears as kiwis left. The number of mangoes left was 11 fewer than the number of pears. How many kiwis were sold?

1 u |
4 u - 11 |
106 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 11
= 9 u - 11
9 u - 11 = 106
9 u = 106 + 11
9 u = 117
1 u = 117 ÷ 9 = 13
Number of mangoes at first
= 4 u - 11 + 55
= 4 x 13 - 11 + 55
= 52 - 11 + 55
= 96
The number of kiwis and mangoes at first was the same.
Number of kiwis sold
= 96 - 1 u
= 96 - 13
= 83
Answer(s): 83
