Steps:

Since the angle about the center of a circle is 360°, divide 360° in proportion to the given data. In this question, divide 360° in proportion 1,800 : 2,700 : 900 : 1,200 to obtain the corresponding central angles.
Make a table as given.

Monthly spends	Rupees (Rs.)	Central Angles
Rent	1,800	$\dfrac{1,800}{7,200} \times 360°$ = 90°
Food	2,700	$\dfrac{2,700}{7,200} \times 360°$ = 135°
Education	900	$\dfrac{900}{7,200} \times 360°$ = 45°
Other	1,200	$\dfrac{1,200}{7,200} \times 360°$ = 60°
Savings	600	$\dfrac{600}{7,200} \times 360°$ = 30°
Total	7,200	360°

Draw a circle of any suitable radius.
For each central-angle, draw a sector.
