Analyzing Employee Data by Department

The question asks us to find the percentage of employees promoted from the HR department relative to the total number of employees working in the HR department. We are given a table with percentage distributions for the total number of employees, male employees, and recently promoted employees across five departments: Accounts, Production, IT, HR, and Marketing. The total numbers for each category are also provided.

Calculating Number of Employees in HR Department

First, we need to determine the total number of employees in the HR department. The table shows that 12% of the total employees are in the HR department. The total number of employees is 1800.

Number of employees in HR = 12% of 1800

Expressed as a calculation:

$$ \text{Employees in HR} = \frac{12}{100} \times 1800 $$ $$ \text{Employees in HR} = 0.12 \times 1800 $$ $$ \text{Employees in HR} = 216 $$

So, there are 216 employees working in the HR department.

Calculating Number of Promoted Employees in HR Department

Next, we need to determine the number of employees who got promoted from the HR department. The table shows that 11% of the recently promoted employees are from the HR department. The total number of recently promoted employees is 600.

Number of promoted employees in HR = 11% of 600

Expressed as a calculation:

$$ \text{Promoted employees in HR} = \frac{11}{100} \times 600 $$ $$ \text{Promoted employees in HR} = 0.11 \times 600 $$ $$ \text{Promoted employees in HR} = 66 $$

So, 66 employees from the HR department were recently promoted.

Finding the Percentage of Promoted Employees in HR

We want to find what percentage the number of promoted employees in HR (66) is of the total number of employees in HR (216).

Percentage = $\left( \frac{\text{Number of promoted employees in HR}}{\text{Total number of employees in HR}} \right) \times 100$

Substituting the calculated values:

$$ \text{Percentage} = \left( \frac{66}{216} \right) \times 100 $$

Now, we perform the calculation:

$$ \text{Percentage} = 0.30555... \times 100 $$ $$ \text{Percentage} \approx 30.555 $$

Rounding to two decimal places, the percentage is approximately 30.56%.

Conclusion

The number of employees who got promoted from the HR department is approximately 30.56% of the total number of employees working in the HR department.

Additional Information: Percentage Calculations in Data Interpretation

In data interpretation questions involving percentages, it's crucial to identify the correct base for the percentage calculation. For example, a percentage of promoted employees from a specific department refers to the promoted employees from that department as a proportion of the *total* employees in that department, unless otherwise specified. Similarly, understanding that percentages in a table represent proportions of different totals (e.g., % of total employees vs. % of total promoted employees) is key to setting up the calculations correctly. Always read the column headers carefully to determine what the percentages represent.
