                The number of students in a hostel, speaking different languages is given below. Display the data in a pie chart.                                                       

Language	Hindi	English	Marathi	Tamil	Bengali	Total
Hindi	40	\[\frac{40}{72}=\frac{5}{9}\]
English	12	\[\frac{12}{72}=\frac{1}{6}\]
Marathi	9	\[\frac{8}{72}=\frac{1}{9}\]
Tamil	7	\[\frac{7}{72}\]
Bengali	4	\[\frac{4}{72}=\frac{1}{18}\]
Total	72	1

Answer:

Language	Number of Students	In Fraction	Central angle
Hindi	40	\[\frac{40}{72}=\frac{5}{9}\]	\[\frac{5}{9}\times {{360}^{\text{o}}}={{200}^{\text{o}}}\]
English	12	\[\frac{12}{72}=\frac{1}{6}\]	\[\frac{1}{6}\times {{360}^{\text{o}}}={{60}^{\text{o}}}\]
Marathi	9	\[\frac{8}{72}=\frac{1}{9}\]	\[\frac{1}{9}\times {{360}^{\text{o}}}={{40}^{\text{o}}}\]
Tamil	7	\[\frac{7}{72}\]	\[\frac{7}{72}\times {{360}^{\text{o}}}={{35}^{\text{o}}}\]
Bengali	4	\[\frac{4}{72}=\frac{1}{18}\]	\[\frac{1}{18}\times {{360}^{\text{o}}}={{20}^{\text{o}}}\]
Total	72	1	\[{{360}^{\text{o}}}\]

Now, we make the pie chart.
