What is the concentration of cocoa in the resulting mixture?

Answers

  1. Answer:

    180 grams

    Step-by-step explanation:

    Given that:

    Grams of dark chocolate = 200

    % cocoa = 60%

    Grams of milk chocolate = 200

    % cocoa = 30%

    Amount of cocoa in resulting mixture :

    (Proportion of milk chocolate + proportion of dark chocolate)

    (30% of 200) + (60% of 200)

    (0.3 * 200) + (0.6 * 200)

    60 + 120

    = 180 grams
