Percentage of chocolate bars after Gabriel received from Glen
= 100% + 25%
= 125%
Percentage of Gabriel's chocolate bars that Winnie had after receiving from Gabriel
= 60% x 125%
=
60100 x 125%
= 75%
Percentage of chocolate bars that Gabriel had left after giving to Winnie
= 125% - 75%
= 50%
100% = 70
Number of chocolate bars that Gabriel had left
= 50% x 70
=
50100 x 70
= 35
