$\begin{array}{cc}\text{Language}& \text{No. of Students}\\ \text{Hindi}& 40\\ \text{English}& 12\\ \text{Marathi}& 9\\ \text{Tamil}& 7\\ \text{Bengali}& 4\\ \text{Total}& 72\end{array}$
If a pie chart is drawn for the above data, what is the central angle for the number of students speaking hindi?

• A. ${200}^{\circ }$
• B. ${100}^{\circ }$
• C. ${60}^{\circ }$
• D. ${35}^{\circ }$

Answer 1

The correct option is A

${200}^{\circ }$

Total number of students = 72

Then 72 = $={360}^{\circ }$
Therefore, central angle for number of students speaking hindi $=\frac{40}{72}\times {360}^{\circ }={200}^{\circ }$
