Percentage of mini cupcakes after George received from Cody
= 100% + 20%
= 120%
Percentage of George's mini cupcakes that Esther had after receiving from George
= 50% x 120%
=
50100 x 120%
= 60%
Percentage of mini cupcakes that George had left after giving to Esther
= 120% - 60%
= 60%
100% = 10
Number of mini cupcakes that George had left
= 60% x 10
=
60100 x 10
