Percentage of candy canes after Lui received from Oliver
= 100% + 25%
= 125%
Percentage of Lui's candy canes that Tina had after receiving from Lui
= 60% x 125%
=
60100 x 125%
= 75%
Percentage of candy canes that Lui had left after giving to Tina
= 125% - 75%
= 50%
100% = 20
Number of candy canes that Lui had left
= 50% x 20
=
50100 x 20
= 10
