Number of apples that Luis used
=
411 x 198
= 72
Number of apples that Luis had left
= 198 - 72
= 126
Number of mangoes that Luis used
=
45 x 165
= 132
Number of mangoes that Luis had left
= 165 - 132
= 33
Fraction of the fruits left that were mangoes
= 1 -
16=
56 Number of apples left = 1 u = 126
Number of mangoes left in the end
= 5 u
= 5 x 126
