Number of mangoes that Jenson used
=
38 x 184
= 69
Number of mangoes that Jenson had left
= 184 - 69
= 115
Number of kiwis that Jenson used
=
49 x 72
= 32
Number of kiwis that Jenson had left
= 72 - 32
= 40
Fraction of the fruits left that were kiwis
= 1 -
19=
89 Number of mangoes left = 1 u = 115
Number of kiwis left in the end
= 8 u
= 8 x 115
= 920
Number of kiwis that Jenson bought
= 920 - 40
= 880
Answer(s): 880
