Analysing Civil Services Exam Pass Percentage in 2019

The question asks us to determine which city among K, L, M, and N had the minimum percentage of candidates who passed the Civil Services Examination compared to those who appeared in the year 2019. To answer this, we need to extract the relevant data for the year 2019 from the provided table and calculate the pass percentage for each city.

Extracting Data for Year 2019

Let's look at the data provided in the table for the year 2019 for each city:

Calculating Pass Percentage for Each City in 2019

The pass percentage for a city is calculated using the formula:

$$\text{Pass Percentage} = \left( \frac{\text{Number of Candidates Passed}}{\text{Number of Candidates Appeared}} \right) \times 100$$

Let's calculate the pass percentage for each city for the year 2019:

City K Pass Percentage (2019)

For City K, Appeared = 850, Passed = 496.

$$\text{Pass Percentage (K)} = \left( \frac{496}{850} \right) \times 100$$ $$\text{Pass Percentage (K)} \approx 0.5835 \times 100 \approx 58.35\%$$

City L Pass Percentage (2019)

For City L, Appeared = 600, Passed = 315.

$$\text{Pass Percentage (L)} = \left( \frac{315}{600} \right) \times 100$$ $$\text{Pass Percentage (L)} = 0.525 \times 100 = 52.5\%$$

City M Pass Percentage (2019)

For City M, Appeared = 740, Passed = 464.

$$\text{Pass Percentage (M)} = \left( \frac{464}{740} \right) \times 100$$ $$\text{Pass Percentage (M)} \approx 0.6270 \times 100 \approx 62.70\%$$

City N Pass Percentage (2019)

For City N, Appeared = 1165, Passed = 780.

$$\text{Pass Percentage (N)} = \left( \frac{780}{1165} \right) \times 100$$ $$\text{Pass Percentage (N)} \approx 0.6695 \times 100 \approx 66.95\%$$

Comparing Pass Percentages in 2019

Now, let's list the calculated pass percentages for each city in 2019:

• City K: Approximately 58.35%
• City L: 52.5%
• City M: Approximately 62.70%
• City N: Approximately 66.95%

Comparing these values, we can see the percentages are: 58.35% (K), 52.5% (L), 62.70% (M), 66.95% (N).

The minimum percentage among these is 52.5%, which corresponds to City L.

Therefore, the percentage of candidates passed among those who appeared for the examination is minimum in the year 2019 for City L.

This table clearly shows that City L has the lowest pass percentage in 2019.

Additional Information: Understanding Percentages in Data Analysis

Percentages are frequently used in data analysis to compare proportions across different groups or categories. A percentage expresses a quantity as a fraction of 100. In this context, calculating the pass percentage helps us understand the success rate of candidates in each city relative to the number who attempted the exam, providing a standardized measure for comparison. A lower pass percentage indicates that a smaller proportion of appeared candidates successfully passed the exam in that particular city and year.
