Question

Draw a pie chart for the given data.

The following table illustrates the data on the mode of transport used by the office goers to go to their office:

Transport to the office	Walk	Bus	Cycle	Train	Car	Total
Number of office goers	$10$	$12$	$18$	$24$	$8$	$72$

Accepted Answer

Following table illustrates the data on the mode of transport used by the office goers to go to their office:

Transport to the office Walk Bus Cycle Train Car Total

Number of office goers $10$ $12$ $18$ $24$ $8$ $72$

Total number of office goers = $10 + 12 + 18 + 24 + 8 = 72$
Number of office goers in each mode of transport is converted into component parts of $360 °$ , using the formula:
$Central angle for a mode of tranport = {(\frac{Number of office goers using that mode of Transport}{Total number of office goers} \times 360)}^{°}$

Calculation of central angles:

Transport to the office Number of office goers Measure of central angle

Walk $10$ $\frac{10}{72} \times 360 ° = 50 °$

Bus $12$ $\frac{12}{72} \times 360 ° = 60 °$

Cycle $18$ $\frac{18}{72} \times 360 ° = 90 °$

Train $24$ $\frac{24}{72} \times 360 ° = 120 °$

Car $8$ $\frac{8}{72} \times 360 ° = 40 °$

Total $72$ $360 °$

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:

Country	India	USA	Germany	UK	South Africa
Number of stamps	$105$	$150$	$90$	$120$	$75$

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

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	$24000$	$24000$	$18000$	$58000$	$20000$

Draw a pie chart for the given data.

The following table illustrates the data on the mode of transport used by the office goers to go to their office:

Transport to the office Walk Bus Cycle Train Car Total

Number of office goers $10$ $12$ $18$ $24$ $8$ $72$
