Number of persimmons that Tim used
=
57 x 77
= 55
Number of persimmons that Tim had left
= 77 - 55
= 22
Number of chikoos that Tim used
=
34 x 80
= 60
Number of chikoos that Tim had left
= 80 - 60
= 20
Fraction of the fruits left that were chikoos
= 1 -
110=
910 Number of persimmons left = 1 u = 22
Number of chikoos left in the end
= 9 u
= 9 x 22
= 198
Number of chikoos that Tim bought
= 198 - 20
= 178
Answer(s): 178
