The following pie charts give the information about the distribution of weight in the human body according to different kinds of components. Study the pie charts carefully to answer these questions.
We are given in the first graph that skin isĀ $$\dfrac{1}{10}$$,Ā bones is $$\dfrac{1}{5}$$, muscles isĀ $$\dfrac{3}{10}$$ and the rest is others.
The total sum must be equal to 1.
Skin + Bones + Muscles + others = 1
Others = 1 - Skin - Bones - Muscles
OthersĀ $$=\ 1\ -\ \dfrac{1}{10}\ -\ \dfrac{1}{5}\ -\ \dfrac{3}{10}\ =\ \dfrac{10\ -\ 1\ -\ 2\ -\ 3}{10}\ =\ \dfrac{4}{10}$$
Neither bones nor skin = Muscles +Ā others =Ā $$\ \dfrac{3}{10}\ +\ \dfrac{4}{10}\ =\ \dfrac{7}{10}\ =\ \dfrac{7}{10}\ \times\ 100\ =\ 70\%$$
Hence, the correct answer is option D.
