Percentage of mini cupcakes after Archie received from Ethan
= 100% + 25%
= 125%
Percentage of Archie's mini cupcakes that Min had after receiving from Archie
= 60% x 125%
=
60100 x 125%
= 75%
Percentage of mini cupcakes that Archie had left after giving to Min
= 125% - 75%
= 50%
100% = 40
Number of mini cupcakes that Archie had left
= 50% x 40
=
50100 x 40
= 20
