Question

Diet jam contains half the sugar and twice the fruit of regular jam.

Assuming that the ingredients other than sugar and druit make up 4% of both types of jam, what is the percentage of sugar in diet jam?

Answer 1

s + f = 96

s/2 + 2f = 96

Löse das Gleichungssystem und erhalte: f = 32 ∧ s = 64

Die Diätmarmelade enthält daher nur 64/2 = 32 Prozent Zucker.
