1 МБ = 8388608 б
2^18 = 262144 б/с

1МБ информации передается за  8388608 /  262144 = 32 секунды.

Способ А: 
сжать = 20с
+ передать 50% = 4МБ * 50/100 = 2МБ * 32с = 64с
                            8МБ * 50% = 4 * 32 = 128с
 + распаковать = 5с
20 + 64 + 5 = 89с; 20 + 128 + 5 = 153с

Способ Б: 
передать 4МБ = 4МБ * 32с = 128с
               8МБ = 8МБ * 32с = 256с 

128 - 89 = 39с; 256 - 153 = 103с

Ответ: для 4МБ - А39; для 8МБ - А103
