Question

In terms of total body weight, the portion of material other than water and protein is closest to:

• A. $\frac{3}{20}$
• B. $\frac{1}{15}$
• C. $\frac{85}{100}$
• D. $\frac{1}{20}$

Hint:

For "other than" type percentage problems, simply subtract the given category percentages from 100% or directly use the remaining category’s percentage.

Answer 1

The Correct Option is A

From the first pie chart:
- Water = $70%$ of total body weight.
- Protein = $15%$ of total body weight.
- Other dry material = $15%$ of total body weight.
The portion other than water and protein is exactly the "Other dry material" category.
Therefore:
Portion = $15% = \frac{15}{100} = \frac{3}{20}$.
\(\boxed{\text{Correct Answer: (A) $\frac{3}{20}$}}\)
