Answer:
230 Calories
Explanation:
Carbohydrates are the primary source of energy in our body and 4 Calories of energy is provided by each gram of carbohydrates. So 30 gram of carbohydrates will produce;
30 x 4= 120 Calories
Proteins also provide 4 Calories/gram.
5 x 4 = 20 Calories
Fats provide more energy than carbohydrates and proteins and 9 Calories of energy is provided by each gram of fat.
10 x 9 = 90 Calories
Totall energy produced by 30 grams of carbohydrates, 5 gram of proteins and 9 gram of carboydrates;
120 + 20 + 90 = 230 Calories
