Number of mangosteens that Asher used
=
411 x 198
= 72
Number of mangosteens that Asher had left
= 198 - 72
= 126
Number of starfruits that Asher used
=
59 x 144
= 80
Number of starfruits that Asher had left
= 144 - 80
= 64
Fraction of the fruits left that were starfruits
= 1 -
15=
45 Number of mangosteens left = 1 u = 126
Number of starfruits left in the end
= 4 u
= 4 x 126
= 504
Number of starfruits that Asher bought
= 504 - 64
= 440
Answer(s): 440
