Number of kiwis that Simon used
=
411 x 154
= 56
Number of kiwis that Simon had left
= 154 - 56
= 98
Number of chikoos that Simon used
=
58 x 80
= 50
Number of chikoos that Simon had left
= 80 - 50
= 30
Fraction of the fruits left that were chikoos
= 1 -
19=
89 Number of kiwis left = 1 u = 98
Number of chikoos left in the end
= 8 u
= 8 x 98
= 784
Number of chikoos that Simon bought
= 784 - 30
= 754
Answer(s): 754
