Percentage of lollipops after Rael received from Tommy
= 100% + 25%
= 125%
Percentage of Rael's lollipops that Jean had after receiving from Rael
= 40% x 125%
=
40100 x 125%
= 50%
Percentage of lollipops that Rael had left after giving to Jean
= 125% - 50%
= 75%
100% = 100
Number of lollipops that Rael had left
= 75% x 100
=
75100 x 100
= 75
Answer(s): 75
