Calculation: 1 Mark
Graph: 3 Marks

Total 72 $={360}^{\circ }$

so central angle for hindi $=\frac{40}{72}\times {360}^{\circ }={200}^{\circ }$

central angle for english $=\frac{12}{72}\times {360}^{\circ }={60}^{\circ }$

central angle for marathi $=\frac{9}{72}\times {360}^{\circ }={45}^{\circ }$

central angle for tamil $=\frac{7}{72}\times {360}^{\circ }={35}^{\circ }$

central angle for bengali $=\frac{4}{72}\times {360}^{\circ }={20}^{\circ }$
