Question

Draw a pie chart for the given data.

The table given below provides the data on money spent (in crores) during the fourth 'Five Year Plan' :

Item	Agriculture	Communication	Industries	Power	Miscellaneous
Rupees (in crores)	$5250$	$4000$	$3750$	$2250$	$2750$

Accepted Answer

Following table provides the data on money spent (in crores) during the fourth 'Five Year Plan':

Item Agriculture Communication Industries Power Miscellaneous

Rupees (in crores) $5250$ $4000$ $3750$ $2250$ $2750$

Total money spent (in crores) = $5250 + 4000 + 3750 + 2250 + 2750 = 18000$
Money spent in each item is converted into component parts of $360 °$ , using the formula:
$Central angle for an item = {(\frac{Money spent in that item}{Total money spent} \times 360)}^{°}$

Calculation of central angles:

Item Rupees (in crores) Measure of central angle

Agriculture $5250$ $\frac{5250}{18000} \times 360 ° = 105 °$

Communication $4000$ $\frac{4000}{18000} \times 360 ° = 80 °$

Industries $3750$ $\frac{3750}{18000} \times 360 ° = 75 °$

Power $2250$ $\frac{2250}{18000} \times 360 ° = 45 °$

Miscellaneous $2750$ $\frac{2750}{18000} \times 360 ° = 55 °$

Total $18000$ $360 °$

Now we draw a pie chart using the following steps of construction:
$1 .$ Draw a circle with any convenient radius.
$2 .$ Using the protractor, draw sectors corresponding to the central angles calculated in the table above.
$3 .$ Shade/Colour the sectors so obtained differently.
$4 .$ Label each sector.
Thus we obtain the required pie chart as shown in the figure given below:

Item	Education	Food	Rent	Clothing	Others
Expenditure (in $₹$ )	$1600$	$3200$	$4000$	$2400$	$3200$

Subject	Physics	Mathematics	English	Biology	Chemistry
Number of students	$9000$	$35000$	$18000$	$4000$	$6000$

Bank	Standard Chartered	ICICI	SBI	Citibank	Bank of India
Number of credit cards issued	$24000$	$24000$	$18000$	$58000$	$20000$

Item	Rent	Wages	Electricity and Water	Taxation
Amount (in lakhs of $₹$ )	$1560$	$840$	$600$	$1320$

Head	Printing	Paper and binding charges	Advertisement	Royalty	Miscellaneous
Percentage (%)	$\frac{175}{6}$	$\frac{250}{9}$	$\frac{125}{6}$	$\frac{125}{18}$	$\frac{275}{18}$
