    Directions : The following pie chart represents the distribution of proteins in parts of a human body.
    What is the central angle of the sector representing skin and bones together?

    A)  \[{{136}^{{}^\circ }}\left( approx \right)\]        

    B)  \[{{60}^{{}^\circ }}\left( approx \right)\]    

    C)  \[{{90}^{{}^\circ }}\left( approx \right)\]         

    D)  \[{{119}^{{}^\circ }}\left( approx \right)\]

    Correct Answer: D

    Solution :

    (d): \[skin+bones=23%+10%=33%\] \[100%\cong {{360}^{{}^\circ }}\] \[1%\cong {{3.6}^{{}^\circ }}\] \[33%\cong 3.6\times {{33}^{{}^\circ }}={{118.8}^{{}^\circ }}\cong {{119}^{{}^\circ }}.\]
