The following table shows the percentage (%) breakup of (i) number of employees, (ii) number of male employees, and (iii) number of employees who recently got promoted in five different departments, namely, Accounts, Production, IT, HR, and Marketing, of an organization. Total number of employees, male employees and recently promoted employees are 1800, 1020 and 600 respectively. Based on the data in the table, answer the question. Department -wise Breakup of Employees Department Distribution (%) of Employees Number of Employees (1800) Number of Male Employees (1020) Number of recently promoted Employees (600) Accounts 20% 5% 6% Production 35% 50% 35% IT 15% 20% 26% HR 12% 10% 11% Marketing 18% 15% 22%
How many females work in the Accounts department?
This question requires us to calculate the number of female employees specifically within the Accounts department using the data provided in the table. To find the number of females, we need to know the total number of employees in the Accounts department and the total number of male employees in the Accounts department. The difference between these two numbers will give us the number of female employees.
Here is the data table provided:
| Department | Distribution (%) of Employees (1800) | Number of Male Employees (%) (1020) | Number of recently promoted Employees (%) (600) |
|---|---|---|---|
| Accounts | 20% | 5% | 6% |
| Production | 35% | 50% | 35% |
| IT | 15% | 20% | 26% |
| HR | 12% | 10% | 11% |
| Marketing | 18% | 15% | 22% |
The total number of employees in the organization is 1800. The table shows that 20% of the total employees are in the Accounts department.
Total employees in Accounts = 20% of 1800
$$ \text{Total employees in Accounts} = \frac{20}{100} \times 1800 $$
$$ \text{Total employees in Accounts} = 0.20 \times 1800 $$
$$ \text{Total employees in Accounts} = 360 $$
So, there are 360 employees working in the Accounts department.
The total number of male employees in the organization is 1020. The table shows that 5% of the total male employees are in the Accounts department.
Number of male employees in Accounts = 5% of 1020
$$ \text{Male employees in Accounts} = \frac{5}{100} \times 1020 $$
$$ \text{Male employees in Accounts} = 0.05 \times 1020 $$
$$ \text{Male employees in Accounts} = 51 $$
So, there are 51 male employees working in the Accounts department.
The number of female employees in a department is the total number of employees in that department minus the number of male employees in that department.
Number of female employees in Accounts = Total employees in Accounts - Male employees in Accounts
$$ \text{Female employees in Accounts} = 360 - 51 $$
$$ \text{Female employees in Accounts} = 309 $$
Therefore, there are 309 female employees in the Accounts department.
Based on the calculations, the number of females who work in the Accounts department is 309.
| Metric | Calculation | Result |
|---|---|---|
| Total Employees in Accounts | 20% of 1800 | 360 |
| Male Employees in Accounts | 5% of 1020 | 51 |
| Female Employees in Accounts | Total Employees in Accounts - Male Employees in Accounts | 360 - 51 = 309 |
When working with data interpretation problems involving percentages and totals, it's crucial to identify which total corresponds to which percentage distribution. In this question, the percentages for total employees are based on 1800, the percentages for male employees are based on 1020, and the percentages for recently promoted employees are based on 600. Always read the table headings and introductory text carefully to avoid mixing up the bases for percentage calculations. Calculating specific numbers from percentages of different totals is a common technique in data analysis.
