Question

The following pie chart represents the distribution of proteins in parts of the human body. What is the ratio of the distribution of proteins in the muscles to that of proteins in the bones?

• A. $3:1$
• B. $1:2$
• C. $1:3$
• D. $2:1$

Answer 1

The correct option is D

$2:1$

Given:

Distribution of protein in the muscles $=\frac{1}{3}$

Distribution of protein in the bones $=\frac{1}{6}$

The ratio of the distribution of proteins in the muscles to that of proteins in the bones,

= $$\begin{gathered} =\frac{1}{3}˸\frac{1}{6} \\ =\frac{1}{3}\times \frac{6}{1} \\ =\frac{1}{1}\times \frac{2}{1} \\ =\frac{2}{1} \\ =2˸1 \end{gathered}$$

Hence, the ratio of the distribution of proteins in the muscles to that of proteins in the bones is $2:1$
