Percentage of sweets after Jeremy received from Glen
= 100% + 20%
= 120%
Percentage of Jeremy's sweets that Hilda had after receiving from Jeremy
= 50% x 120%
=
50100 x 120%
= 60%
Percentage of sweets that Jeremy had left after giving to Hilda
= 120% - 60%
= 60%
100% = 90
Number of sweets that Jeremy had left
= 60% x 90
=
60100 x 90
= 54
