Number of starfruits that Harry used
=
38 x 80
= 30
Number of starfruits that Harry had left
= 80 - 30
= 50
Number of persimmons that Harry used
=
611 x 187
= 102
Number of persimmons that Harry had left
= 187 - 102
= 85
Fraction of the fruits left that were persimmons
= 1 -
16=
56 Number of starfruits left = 1 u = 50
Number of persimmons left in the end
= 5 u
= 5 x 50
= 250
Number of persimmons that Harry bought
= 250 - 85
= 165
Answer(s): 165
