Rainy 120
Winter 150

(i) Winter season got the most votes (i.e) $150$.

(ii)  Total Votes$ = 90+120+150 = 360$

The central angle of summer $=\frac{90^{\circ}}{360^{\circ}} \times 360^{\circ}=90^{\circ}$

The central angle of rainy $=\frac{120^{\circ}}{360^{\circ}} \times 360^{\circ}=120^{\circ}$

The central angle of winter $=\frac{150^{\circ}}{360^{\circ}} \times 360^{\circ}=150^{\circ}$

(iii) With the help of the central angles calculated, let us draw a pie chart.
