Question

Arrange the specific gravity of milk constituents in increasing order.
A. Fat
B. Mineral/Ash
C. Protein
D. Lactose

• A. A, C, D, B
• B. A, B, C, D
• C. D, C, B, A
• D. A, B, D, C

Hint:

Fat is lighter than water; minerals are the heaviest.

Answer 1

The Correct Option is A

Concept: Specific gravity indicates density relative to water.

Step 1: Values.

• Fat $\approx$ 0.93 (lowest)
• Protein $\approx$ 1.35
• Lactose $\approx$ 1.54
• Minerals $\approx$ 3.0 (highest)

Step 2: Increasing order.
\[ \text{Fat} < \text{Protein} < \text{Lactose} < \text{Minerals} \]

Step 3: Mapping.
\[ A, C, D, B \] Conclusion: Option (1) is correct.
