What is a Pie Chart ?

A pie chart is a circularly shaped geometrical visual graphic that exhibits data, information, figures, and statistics in the format of an easy-to-read ‘pie slice’ with fluctuating sizes describing how much one data component exists. The larger the part, the more of that precise data were grouped.

How to solve Pie Chart Questions and Answers

  • Start with what you want to illustrate: The main topic will be the title of your chart.
  • Gather the data: Pie charts depict percentages. Make sure your percentages add up to 100% and get rid of any rounding issues that would make the total something other than 100%. SmartDraw allows you to write the percentage directly into a pie chart template or you can drag the edge of a wedge to make it bigger or smaller.
  • Consider creating a legend: If a wedge is too small to hold text, you can create a label and draw a line identifying the appropriate slice. Alternatively, you can create a key that shows what each color represents.

Some Important Points about Pie Chart:

  • Pie charts are easy to understand and require minimal effort to interpret.
  • Pie charts are ideal for displaying data that represents parts of a whole, such as budget allocations, market share, or the composition of a population.
  • They are visually appealing and can make your data presentation more engaging and memorable.

For the seller wants to earn 20 % profit, then selling price = 120% of cost price.

Also editing and proofreading cost = 30% of C.P.

Then, let us assume the selling price of 4200 books as x

Then, 30: 120 = 65800: x

x = 120 * 65800 / 30 = 263200

Therefore, selling price of one book = 263200/4200 = Rs. 62.66

: Editing Cost = 30% of the cost price of the book

Formatting cost = 25% of the cost price of the book

Difference = (30%) - (25%) = 5%

Therefore, percentage difference = 5% / Editing cost * 100

= 5/30 * 100 = 16.66%
