Number of mangoes that Glen used
=
411 x 110
= 40
Number of mangoes that Glen had left
= 110 - 40
= 70
Number of pears that Glen used
=
47 x 182
= 104
Number of pears that Glen had left
= 182 - 104
= 78
Fraction of the fruits left that were pears
= 1 -
13=
23 Number of mangoes left = 1 u = 70
Number of pears left in the end
= 2 u
= 2 x 70
= 140
Number of pears that Glen bought
= 140 - 78
= 62
