Number of chikoos that Bobby used
=
37 x 161
= 69
Number of chikoos that Bobby had left
= 161 - 69
= 92
Number of persimmons that Bobby used
=
67 x 63
= 54
Number of persimmons that Bobby had left
= 63 - 54
= 9
Fraction of the fruits left that were persimmons
= 1 -

67 Number of chikoos left = 1 u = 92
Number of persimmons left in the end
= 6 u
