Percentage of candy canes after Ivan received from Ken
= 100% + 40%
= 140%
Percentage of Ivan's candy canes that Xuan had after receiving from Ivan
= 50% x 140%
=
50100 x 140%
= 70%
Percentage of candy canes that Ivan had left after giving to Xuan
= 140% - 70%
= 70%
100% = 70
Number of candy canes that Ivan had left
= 70% x 70
=
70100 x 70
= 49
