    There seems to have been a mistake in either the assigning or the copying of the problem. "Food energy per 100 g" should be stated in either kilogram-Calories or Joules or kilojoules.

    1 kg-Calorie = 4184 Joules oe 4.184 kJ

    In the USA, food labels state food energy in kg-Calories (although the kg is usually omitted) per "serving" size, and the mass or volume of a serving size is defined separately.
