Percentage of mini cupcakes after Henry received from Sam
= 100% + 25%
= 125%
Percentage of Henry's mini cupcakes that Irene had after receiving from Henry
= 60% x 125%
=
60100 x 125%
= 75%
Percentage of mini cupcakes that Henry had left after giving to Irene
= 125% - 75%
= 50%
100% = 70
Number of mini cupcakes that Henry had left
= 50% x 70
=
50100 x 70
= 35
