The table shows how a boy spent his pocket money during a week.
Expenditure | Bus fare | Food | Stationery | Drinks
---|---|---|---|---
Amount | 50k | 80k | 20k | 60k
Draw a bar chart and a pie chart to show this expenditure.
Answer (2)
To represent the boy's expenditure using both a bar chart and a pie chart, we will first understand how these charts work and then proceed step-by-step.
Bar Chart
A bar chart displays data with rectangular bars representing the amount of each category. Each bar's length is proportional to the value it represents.
Steps to Draw a Bar Chart:
Identify the Categories:
Bus fare
Food
Stationery
Drinks
Determine the Amounts for Each Category (in k):
Bus fare: 50
Food: 80
Stationery: 20
Drinks: 60
Draw the Axes:
The x-axis will represent expenditure categories (Bus fare, Food, Stationery, Drinks).
The y-axis will indicate the amount in thousands (k).
Draw Bars for Each Category:
Each category will have a bar corresponding to its amount.
For example, the bar for 'Food' will be 80 units high.
Pie Chart
A pie chart shows data as slices of a circle, with each slice's angle proportional to its value.
Steps to Draw a Pie Chart:
Calculate Total Expenditure:
Total = 50k + 80k + 20k + 60k = 210k
Calculate the Percentage for Each Category:
Bus fare: 210 50 × 100 ≈ 23.81%
Food: 210 80 × 100 ≈ 38.10%
Stationery: 210 20 × 100 ≈ 9.52%
Drinks: 210 60 × 100 ≈ 28.57%
Draw the Pie Chart:
Divide the circle into slices based on the percentage value for each category.
For example, the slice for 'Food' will cover about 38.10% of the circle.
Conclusion
Both the bar chart and pie chart will help visualize how the boy spends his pocket money across different categories. The bar chart highlights the exact amount spent on each category, while the pie chart shows the proportion of each expenditure as part of the whole.
Creating these visual representations can aid in understanding spending patterns and making data-driven decisions.
To visualize the boy's weekly spending, create a bar chart that represents the expenditure amounts for Bus fare, Food, Stationery, and Drinks. Additionally, create a pie chart to illustrate the percentage of total spending for each category. Both charts will provide clear insights into how the boy allocates his pocket money.
