    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

    Answer:

    45%

    Step-by-step explanation:

    200g milk chocolate

    200g dark chocolate

    = 400g of chocolate

    x = the %

    x/100 = 180/400

    18000 = 400x

    x = 45

    45%
