Answer:
180 grams
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
