Number of chikoos that Sam used
=
37 x 84
= 36
Number of chikoos that Sam had left
= 84 - 36
= 48
Number of pears that Sam used
=
38 x 112
= 42
Number of pears that Sam had left
= 112 - 42
= 70
Fraction of the fruits left that were pears
= 1 -
19=
89 Number of chikoos left = 1 u = 48
Number of pears left in the end
= 8 u
= 8 x 48
= 384
Number of pears that Sam bought
= 384 - 70
= 314
