Calculating the Difference in Candidates for City K

The problem asks us to find the difference between the total number of candidates who appeared and the total number of candidates who passed the Civil Services Examination from City K across all six years (2014 to 2019).

First, we need to extract the data for City K from the provided table for each year.

Step 1: Calculate Total Candidates Appeared from City K

We sum the number of candidates who appeared from City K for all years from 2014 to 2019.

Total Appeared $= 782 + 804 + 720 + 750 + 824 + 850$

Total Appeared $= 4730$

Thus, the total number of candidates who appeared from City K over the six years is 4730.

Step 2: Calculate Total Candidates Passed from City K

Next, we sum the number of candidates who passed from City K for all years from 2014 to 2019.

Total Passed $= 360 + 472 + 448 + 360 + 504 + 496$

Total Passed $= 2640$

So, the total number of candidates who passed from City K over the six years is 2640.

Step 3: Calculate the Difference

The question asks for the difference between the total candidates who appeared and the total candidates who passed from City K. We subtract the total passed from the total appeared.

Difference = Total Appeared - Total Passed

Difference $= 4730 - 2640$

Difference $= 2090$

The difference between the total candidates who appeared and the total candidates who passed from City K in all the six years together is 2090.

Summary of Calculations

We can summarize the totals and the difference:

• Total Appeared (City K, 2014-2019): 4730
• Total Passed (City K, 2014-2019): 2640
• Difference: $4730 - 2640 = 2090$

Additional Information: Analyzing Data Tables

Data interpretation questions often involve analyzing tables that contain structured information. To effectively answer questions based on tables, follow these steps:

• Understand the Table Structure: Look at the rows, columns, and headings. Understand what each cell represents. In this table, rows represent years and cities, while columns show 'Appeared' (A) and 'Passed' (P) for each city.
• Identify the Specific Data Needed: Read the question carefully to know exactly which data points are required. Here, we needed data only for City K.
• Perform Calculations: Based on the question, perform the necessary calculations like summing, averaging, finding percentages, ratios, differences, etc.
• Be Mindful of Units and Context: Ensure you are using the correct numbers for the required calculation. Double-check additions and subtractions.
• Review Your Work: Before concluding, quickly review the steps and calculations to avoid simple errors.

Practicing with different types of data tables helps improve speed and accuracy in data interpretation questions.
