• C. $\frac{85}{100}$
• D. $\frac{1}{20}$

Answer 1

The Correct Option is B

From the first pie chart, we know that the total protein content in Ghosh Babu’s body is $15%$ of his total body weight.
From the second pie chart, we know that this total protein is distributed among various organs:
- Skin: $8%$ of total protein weight
- Bones: $15%$ of total protein weight
- Muscles: $25%$ of total protein weight
- Other proteins: $52%$ of total protein weight
We are asked about muscular and skin protein combined.
Muscle protein share = $25%$ of total protein weight.
Skin protein share = $8%$ of total protein weight.
Therefore, the combined percentage of protein (relative to total protein weight) from muscle and skin is:
$25% + 8% = 33%$ of the total protein.
Now, the protein content itself is $15%$ of the total body weight.
Thus, muscular + skin protein = $33%$ of $15%$ of body weight.
Calculation:
$0.33 \times 0.15 = 0.0495$ of total body weight.
In fractional form:
$0.0495 \approx \frac{1}{20.2}$ but exactly,
$\frac{33}{100} \times \frac{15}{100} = \frac{495}{10000} = \frac{99}{2000}$.
Now, $\frac{99}{2000} = \frac{1}{20.202...}$, but among the given options, the closest exact match is $\frac{1}{30}$? Wait, let's check:
Actually, $33%$ means $\frac{33}{100}$ and $15%$ means $\frac{15}{100}$.
Multiplication gives: $\frac{33 \times 15}{100 \times 100} = \frac{495}{10000}$.
This is $\frac{99}{2000}$. In decimal: $0.0495$.
$0.0495$ in fractional approximation is close to $\frac{1}{20}$.
Rechecking the given options — correct nearest fraction match to $0.0495$ is actually $\frac{1}{20}$.
So the answer should be option (C) $\frac{1}{20}$.
\(\boxed{\text{Correct Answer: (C) $\frac{1}{20}$}}\)

Answer 2

From the second pie chart, protein distribution in:
- Muscles = $25%$ of total protein weight.
- Skin = $8%$ of total protein weight.
We take the ratio:
Muscle : Skin = $25 : 8$.
Now, $25:8$ simplifies by dividing both numbers by their GCD (which is 1), so it remains $25:8$.
However, if we express $25:8$ approximately in whole number ratio form with small integers, we get:
$25 \div 8 \approx 3.125 \Rightarrow \text{about } 3:1$.
Given the options, the ratio is best represented as $3:1$.
\(\boxed{\text{Correct Answer: (A) $3:1$}}\)

Answer 3

Total protein in the body = $15%$ of body weight.
Skin protein share = $8%$ of the protein weight.
Therefore, percentage of total body weight made up of skin protein is:
$8%$ of $15%$ = $\frac{8}{100} \times \frac{15}{100} = \frac{120}{10000} = 0.012$.
Converting to percentage:
$0.012 \times 100 = 1.2%$.
Hence, skin accounts for $1.2%$ of the total body weight.
\(\boxed{\text{Correct Answer: (C) 1.2}}\)

Answer 4

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 = $15% = \frac{15}{100} = \frac{3}{20}$.
\(\boxed{\text{Correct Answer: (A) $\frac{3}{20}$}}\)
