Number of apples that Japheth used
=
37 x 182
= 78
Number of apples that Japheth had left
= 182 - 78
= 104
Number of mangosteens that Japheth used
=
47 x 126
= 72
Number of mangosteens that Japheth had left
= 126 - 72
= 54
Fraction of the fruits left that were mangosteens
= 1 -
18=
78 Number of apples left = 1 u = 104
Number of mangosteens left in the end
= 7 u
= 7 x 104
= 728
Number of mangosteens that Japheth bought
= 728 - 54
= 674
