Percentage of lollipops after Oscar received from Glen
= 100% + 25%
= 125%
Percentage of Oscar's lollipops that Erika had after receiving from Oscar
= 40% x 125%
=
40100 x 125%
= 50%
Percentage of lollipops that Oscar had left after giving to Erika
= 125% - 50%
= 75%
100% = 100
Number of lollipops that Oscar had left
= 75% x 100
=
75100 x 100
= 75
