Number of mangoes that Seth used
=
411 x 154
= 56
Number of mangoes that Seth had left
= 154 - 56
= 98
Number of mangosteens that Seth used
=
78 x 56
= 49
Number of mangosteens that Seth had left
= 56 - 49
= 7
Fraction of the fruits left that were mangosteens

56 Number of mangoes left = 1 u = 98
Number of mangosteens left in the end
= 5 u
