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.

Let the amount paid for promotion be x
Then, 20: 15 = 21500: x
x = 21500 * 15/20 = 16125
Therefore, the amount paid for promotion is Rs. 16125 2. The following pie-chart displays the percentage distribution of the cost in self-publishing a book.

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 4. The following pie-chart displays the percentage distribution of the cost in self-publishing a book. Study the pie-chart below and then answer the questions accordingly. By how much amount the formatting of the book is a lesser amount for editing the book? 25%

: 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% 5. The pie-charts below displays the percentage distribution of people going out of India and the age group of those people. Study the pie-chart below carefully and then answer the questions accordingly.  What percent of Indian people went to UK or Singapore? 35%

Tourist from other countries to Germany is 25%

Among that 25%, 27% is Indian people

Therefore, 27% of 25% = 2% corresponding to Indian people in Germany

2% corresponds of Germany’s 20 Lakh.

1% = 10 lakh.

Therefore 18%(25-35 year of age) = 18 * 10 = 180 Lakh people. 8.
