Number of mangosteens that Perry used
=
38 x 64
= 24
Number of mangosteens that Perry had left
= 64 - 24
= 40
Number of persimmons that Perry used
=
34 x 144
= 108
Number of persimmons that Perry had left
= 144 - 108
= 36
Fraction of the fruits left that were persimmons
= 1 -
16=
56 Number of mangosteens left = 1 u = 40
Number of persimmons left in the end
= 5 u
= 5 x 40
= 200
Number of persimmons that Perry bought
= 200 - 36
= 164
Answer(s): 164
