Percentage of lollipops after John received from Elijah
= 100% + 20%
= 120%
Percentage of John's lollipops that Jane had after receiving from John
= 50% x 120%
=
50100 x 120%
= 60%
Percentage of lollipops that John had left after giving to Jane
= 120% - 60%
= 60%
100% = 40
Number of lollipops that John had left
= 60% x 40
=
60100 x 40
= 24
