Calculating the Difference in Type-C Car Production Between 2019 and 2020

This problem requires us to analyze the provided table showing the percentage distribution of different types of cars produced by a company over two years and calculate the specific difference in the production quantity for Type-C cars.

Analyzing the Car Production Data

We are given the total number of cars produced in two consecutive years, 2019 and 2020, and the percentage breakup of five different car types (A, B, C, D, E) for each year. To find the difference in the production of Type-C cars, we first need to calculate the actual number of Type-C cars produced in each year.

Here is the distribution data:

Step-by-Step Calculation of Type-C Car Production

Step 1: Calculate Type-C Car Production in 2019

In 2019, the total production was 4,50,000 cars. The percentage of Type-C cars produced was 30%.

Number of Type-C cars produced in 2019 = Percentage of Type-C cars in 2019 × Total production in 2019

Number of Type-C cars in 2019 = $\frac{30}{100} \times 4,50,000$

Number of Type-C cars in 2019 = $0.30 \times 4,50,000 = 1,35,000$

So, 1,35,000 Type-C cars were produced in 2019.

Step 2: Calculate Type-C Car Production in 2020

In 2020, the total production was 5,20,000 cars. The percentage of Type-C cars produced was 25%.

Number of Type-C cars produced in 2020 = Percentage of Type-C cars in 2020 × Total production in 2020

Number of Type-C cars in 2020 = $\frac{25}{100} \times 5,20,000$

Number of Type-C cars in 2020 = $0.25 \times 5,20,000 = 1,30,000$

So, 1,30,000 Type-C cars were produced in 2020.

Step 3: Calculate the Difference in Type-C Car Production

To find the difference, we subtract the smaller number of cars from the larger number.

Difference = Number of Type-C cars in 2019 - Number of Type-C cars in 2020

Difference = $1,35,000 - 1,30,000 = 5,000$

The difference in the production of Type-C cars between 2019 and 2020 was 5,000.

Conclusion on Car Production Difference

The difference in the production quantity of Type-C cars between the years 2019 and 2020 is 5,000.

Additional Information on Data Interpretation

Data interpretation questions often involve extracting relevant information from tables, charts, or graphs and performing calculations based on percentages, ratios, averages, or differences. Key steps usually include:

• Carefully reading the question to understand what is being asked.
• Identifying the specific data points needed from the table or chart.
• Understanding the units (e.g., total numbers, percentages).
• Applying the correct mathematical operations (addition, subtraction, multiplication, division, percentage calculation).
• Performing calculations accurately.
• Double-checking the result against the options provided.

In this problem, converting the percentages into actual numbers for each year was the crucial first step before calculating the difference.
