Table shows the monthly expenditure on different items:

What is the difference between the central angle of sectors for Food and Rent when data given in the table is presented in a pie-chart?

90°

Difference between the central angle of sectors for Food and Rent = 4000 - 1500 = 2500

We know that,

Total expenditure = 360^o

10000 = 360^o

then, 2500 = 90^o
