Number of chikoos that Warren used
=
57 x 119
= 85
Number of chikoos that Warren had left
= 119 - 85
= 34
Number of mangoes that Warren used

38 x 128
= 48
Number of mangoes that Warren had left
= 128 - 48
= 80
Fraction of the fruits left that were mangoes
= 1 -

89 Number of chikoos left = 1 u = 34
Number of mangoes left in the end
= 8 u
