Items of expenditure			Amount spent (Rs)
(a)		Food and fuel		1,250
(b)		Clothing		400
(c)		Rent		800
(d)		Education		550
(e)		Savings		600

Answer 1

Total expenditure = Rs.3600

Angle at the center of the circle = 360°

Ratio between the angle at the center and total time

= 360°: 3600

=

Angle of each sector

Activity		Amount Spent (In Rs.)		Angle of the sector
Food and fuel		1250		1250 × = 125°
Clothing		400		400 × = 40°
Rent		800		800 × = 80°
Education		550		550 × = 55°
Savings		600		600 × = 60°
Total		3600		360°

Following is the required pie chart:
