Question

The following pie chart gives the distribution of constituents in the human body. The central angle of the part showing the distribution of protein and dry elements is

• A. ${68}^{\circ }$
• B. ${90}^{\circ }$
• C. ${108}^{\circ }$
• D. ${100}^{\circ }$

Answer 1

The correct option is C ${108}^{\circ }$

The sum of protein and dry elements is $16\%+14\%=30\%$
$\therefore \text{Required central angle}=\frac{\text{percentage of protein and dry elements}}{100}\times {360}^{\circ }$
$\frac{30}{100}\times {360}^{\circ }={108}^{\circ }$
The central angle of the sector showing the distribution of protein and dry elements is ${108}^{\circ }$.
