Question

What is the central angle corresponding to the total number of cellular phones (both Nokia and Samsung) sold by store S?

• A. ${99.2}^{\circ }$
• B. ${93.6}^{\circ }$
• C. ${100.8}^{\circ }$
• D. ${97.4}^{\circ }$
• E. ${101.2}^{\circ }$

Answer 1

The correct option is C ${100.8}^{\circ }$


Total Number = 11200
$\begin{array}{cc}Store& Nokia/Samsung\\ P& 4:3\\ Q& 3:1\\ R& 5:4\\ S& 7:6\\ T& 1:4\\ U& 11:10\end{array}$
We know, 100% = ${360}^{\circ }$
So, 1 = ${3.6}^{\circ }$
So, 28% = 28 $\times$ 3.6 = ${100.8}^{\circ }$
