& (v) 50

• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (III), (B) - (IV), (C) - (II), (D) - (V)
• (A) - (IV), (B) - (V), (C) - (I), (D) - (III)
• (A) - (I), (B) - (IV), (C) - (V), (D) - (II)

Hint:

Remember the standard Atwater factors: multiply carbohydrates and proteins by 4, and fats by 9. This makes calculating calorie values straightforward.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
To determine the calorie contribution of foods, we use the physiological energy values of macronutrients (Atwater factors):
- Carbohydrates: 4 Kcal/g
- Proteins: 4 Kcal/g
- Fats: 9 Kcal/g
- Dietary fiber: Under standard Indian dietary estimations, dietary fiber is partially fermented in the large intestine, contributing approximately 2 Kcal/g of physiological energy.
Key Formula or Approach:
Calculate the energy contribution for each item:
- Energy (Carbohydrate) = $\text{Weight (g)} \times 4\text{ Kcal/g}$
- Energy (Protein) = $\text{Weight (g)} \times 4\text{ Kcal/g}$
- Energy (Fat) = $\text{Weight (g)} \times 9\text{ Kcal/g}$
- Energy (Fiber) = $\text{Weight (g)} \times 2\text{ Kcal/g}$

Step 2: Detailed Explanation:
Let us perform the calculations:
- (A) 70g carbohydrate from rice:
\[ 70\text{ g} \times 4\text{ Kcal/g} = 280\text{ Kcal} \rightarrow \text{(III)} \]
- (B) 30g protein from dal:
\[ 30\text{ g} \times 4\text{ Kcal/g} = 120\text{ Kcal} \rightarrow \text{(IV)} \]
- (C) 15g butter (Fat):
\[ 15\text{ g} \times 9\text{ Kcal/g} = 135\text{ Kcal} \rightarrow \text{(II)} \]
- (D) 25g dietary fibre:
\[ 25\text{ g} \times 2\text{ Kcal/g} = 50\text{ Kcal} \rightarrow \text{(V)} \]
This gives the sequence: (A) - (III), (B) - (IV), (C) - (II), (D) - (V).
This matches Option (B).

Step 3: Final Answer:
The correct matching sequence is (A) - (III), (B) - (IV), (C) - (II), (D) - (V).
