- 144
- 126
- 164
- 112
Correct Option: A
Physiological value of carbohydrates is 4.0 kcal/g, proteins 4.0 kcal/g and of fats is 9.0 kcal/g. Hence,
5 g raw sugar will yield 5 × 4.0 = 20.0 kcal
4 g albumin (protein) will yield 4 × 4.0
= 16.0 kcal
10 + 2 g of fat will yield 12 × 9.0 = 108.0 kcal
Total yield = 144 kcal.
