The given data can be represented as a pie chart.

To represent the given data as a pie chart, calculate the central angles for each section 

Central angle for people who chose North Indian food $=\frac{30}{120} \times 360^{\circ}=\frac{1}{4} \times 360^{\circ}=90^{\circ}$

Central angle for people who chose South Indian food $=\frac{40}{120} \times 360^{\circ}=\frac{1}{3} \times 360^{\circ}=120^{\circ}$

Central angle for people who chose Chinese food $=\frac{25}{120} \times 360^{\circ}=\frac{5}{24} \times 360^{\circ}=75^{\circ}$

Central angle for people who chose Other food $=\frac{25}{120} \times 360^{\circ}=\frac{5}{24} \times 360^{\circ}=75^{\circ}$
