Number of mangoes that Tom used
=
45 x 65
= 52
Number of mangoes that Tom had left
= 65 - 52
= 13
Number of pears that Tom used
=
45 x 70
= 56
Number of pears that Tom had left
= 70 - 56
= 14
Fraction of the fruits left that were pears
= 1 -
14=
34 Number of mangoes left = 1 u = 13
Number of pears left in the end
= 3 u
= 3 x 13
= 39
Number of pears that Tom bought
= 39 - 14
= 25
