Type of Commodity

Expenditure (in rupees)

Food

300

Rent

200

Clothes

125

Education

110

Miscellaneous

Sum of expenditure =Rs. 300+Rs. 200+Rs. 125+Rs.110+Rs.75+RS.90
Sum of expenditure =Rs. 900
So, Rs.900 is equivalent to 360. Re.1 is equivalent to 360900. Rs.200 is equivalent to  360900×200
Rs.200 is equivalent to 40×2
Rs.200 is equivalent to 80 So, item Rent subtends 80 at the center of the pie chart.
Hence, the correct option is 2.
