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%
