Question

Moisture content of grain is 22% on wet basis, what will be its value in dry basis:

• A. 48.2%
• B. 38.3%
• C. 28.2%
• D. 18.2%

Hint:

Dry basis value is ALWAYS higher than the wet basis value.

Answer 1

The Correct Option is C

Step 1: Concept Moisture content can be expressed on a Wet Basis ($M_w$) or Dry Basis ($M_d$).

Step 2: Meaning The conversion formula is: $M_d = \frac{M_w}{100 - M_w} \times 100$.

Step 3: Analysis Given $M_w = 22%$. Calculation: $M_d = \frac{22}{100 - 22} \times 100 = \frac{22}{78} \times 100$. $22 \div 78 \approx 0.28205$.

Step 4: Conclusion $0.28205 \times 100 = 28.2%$.
Final Answer: (C)
