If a person obtains 9450 kcal of energy then he has most likely consumed either
(A) 1000 g of fats
(B) 1000 g of carbohydrate and 500 g of fats
(C) 2000 g of proteins and 1000 g of fats
(D) 927 g of carbohydrates and 100 g of proteins
Calories obtained from 1000g fats = 1000 x 9 = 9000 calories
Calories obtained from 1000g carbohydrates and 500g fats = 1000 x 4 + 500 x 9 = 9500 calories
Calories obtained from 2000g proteins and 1000g fats = 2000 x 4 + 1000 x 9 = 17,000 calories
Calories obtained from 927g carbohydrates and
100g proteins = 927 X 4 + 100 X 4 = 4108 calories
So, the correct answer is 'A and B'.
