Question

On a particular day, the sales (in Rupees) of different items of a baker’s shop are given below. Draw a pie chart for this data.

Item	Ordinary bread	Fruit bread	Cakes	Biscuits	Others
Money (rupees)	320	80	160	120	40

Answer 1

Hint: Here there are different items with different sales. Add the sales of all items. Get the percentage fraction of each item by dividing its sale by total sales. Multiply the percentage fraction with 360 to get the area it occupies on a pie chart.

Complete step-by-step answer:
We are given the sales in rupees of different items of a baker’s shop.

Item	Ordinary bread	Fruit bread	Cakes	Biscuits	Others
Money (rupees)	320	80	160	120	40

We have to draw a pie chart for this data.
Total sales = Sum of all sales of different items.
 $ = 320 + 80 + 160 + 120 + 40 = 720 $
Divide sales of each item with 720 and multiply it with 360
Percentage fraction of Ordinary bread is $ \dfrac{{320}}{{720}} = \dfrac{4}{9} $
 $ \dfrac{4}{9} \times 360 = {160^ \circ } $
Percentage fraction of Fruit bread is $ \dfrac{{80}}{{720}} = \dfrac{1}{9} $
 $ \dfrac{1}{9} \times 360 = {40^ \circ } $
Percentage fraction of Cakes is $ \dfrac{{160}}{{720}} = \dfrac{2}{9} $
 $ \dfrac{2}{9} \times 360 = {80^ \circ } $
Percentage fraction of Biscuits is $ \dfrac{{120}}{{720}} = \dfrac{1}{6} $
 $ \dfrac{1}{6} \times 360 = {60^ \circ } $
Percentage fraction of others is $ \dfrac{{40}}{{720}} = \dfrac{1}{{18}} $
 $ \dfrac{1}{{18}} \times 360 = {20^ \circ } $
Now using these values of angles draw a pie chart.
Draw a circle with a certain radius and mark its centre.
Draw a radius at any point on the circle and using this radius of circle as the base of the protractor, marks 160 which is the highest angle on it.

Using the Ordinary bread boundary, mark the next highest angle and repeat this for all other items.

Therefore, the pie chart is ready.

Note: A pie chart which is also called as a circle chart is a circular statistical graphic, which is divided into parts to illustrate numerical proportion. In a pie chart, the arc length of each part is proportional to the quantity it represents.
