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%
