a.35%
b.28%
c.54%
d.22%

% Calories of carbohydrates=54%

So option C is correct which is 54%

Step-by-step explanation:

In order to find the kilocalories of carbohydrates in the dinner we first have to convert grams of carbohydrates,protein and fat into kilocalories.

1 gram of carbohydrate≈ 4 kilocalories

1 gram of protein≈ 4 kilocalories

1 gram of fat≈ 9 kilocalories

Calories in 210 grams of Carbohydrates=210*4=840

Calories in 60 grams of protein=60*4=240

Calories in 52 grams of fat=52*9=468

Total Calories=Calories of carbs+Calories of protein+Calories of fat

Total Calories=840+240+468

Total Calories=1548

% Calories of carbohydrates= (Calories of carbohydrates/Total Calories)*100

% Calories of carbohydrates=(840/1548)*100

% Calories of carbohydrates=0.54*100

% Calories of carbohydrates=54%

So option C is correct which is 54%
