Percentage of caramel apples after Pierre received from Ivan
= 100% + 20%
= 120%
Percentage of Pierre's caramel apples that Yoko had after receiving from Pierre
= 50% x 120%
=
50100 x 120%
= 60%
Percentage of caramel apples that Pierre had left after giving to Yoko
= 120% - 60%
= 60%
100% = 40
Number of caramel apples that Pierre had left
= 60% x 40
=
60100 x 40
= 24
