Percentage of sweets after Valen received from Michael
= 100% + 25%
= 125%
Percentage of Valen's sweets that Linda had after receiving from Valen
= 60% x 125%
=
60100 x 125%
= 75%
Percentage of sweets that Valen had left after giving to Linda
= 125% - 75%
= 50%
100% = 30
Number of sweets that Valen had left
= 50% x 30
=
50100 x 30
= 15
