Construct a Pareto chart to represent the expenditure of a household with the following details: Food Rs. 800, Clothing Rs. 500, Education Rs. 400, Fuel Rs. 200, Misc. Rs. 100.

Total expenditure $= 800 + 500 + 400 + 200 + 100 = 2000$ Rs.

• Food: $\frac{800}{2000} \times 100\% = 40\%$
• Clothing: $\frac{500}{2000} \times 100\% = 25\%$
• Education: $\frac{400}{2000} \times 100\% = 20\%$
• Fuel: $\frac{200}{2000} \times 100\% = 10\%$
• Misc.: $\frac{100}{2000} \times 100\% = 5\%$

A Pareto chart is a bar chart where the bars are arranged in descending order of frequency or cost, combined with a line graph that shows the cumulative percentage.

• The x-axis would list the items in the order: Food, Clothing, Education, Fuel, Misc.
• The left y-axis would represent the expenditure in Rupees, ranging from 0 to 800. Bars would be drawn for each item corresponding to its expenditure.
• The right y-axis would represent the cumulative percentage, ranging from 0% to 100%. A line graph would be plotted using the cumulative percentages for each item.

The table above provides all the necessary data to construct the Pareto chart.
