Number of chikoos that Ivan used
=
37 x 147
= 63
Number of chikoos that Ivan had left
= 147 - 63
= 84
Number of apples that Ivan used
=
45 x 200
= 160
Number of apples that Ivan had left
= 200 - 160
= 40
Fraction of the fruits left that were apples
= 1 -
19=
89 Number of chikoos left = 1 u = 84
Number of apples left in the end
= 8 u
= 8 x 84
= 672
Number of apples that Ivan bought
= 672 - 40
= 632
Answer(s): 632
