Understanding Staff Distribution in a Five Star Corporation

This problem requires us to interpret data from a table showing the distribution of women staff across different grades in a corporation and use additional notes to calculate the number of men in Managerial Grades.

Calculating Women Staff in Different Grades

First, let's extract the number of women staff from the provided table for both Professional and Managerial Grades.

Now, let's sum up the number of women in each grade type:

• Total women in Professional Grades = $30 + 15 + 15 + 20 + 10 = 90$ women.
• Total women in Managerial Grades = $25 + 1 + 4 = 30$ women.

Using Corporation Notes to Find Staff Numbers

The problem provides additional notes that give us more information about the staff distribution:

• Note (a): There are five times as many men in Professional Grades as women.
• Note (b): The Corporation employs a total of 1300 staff in both Professional and Managerial Grades.
• Note (c): 8% of the total workforce at the Corporation is employed in Professional and Managerial Grades.

Using Note (a), we can calculate the number of men in Professional Grades:

Number of men in Professional Grades = $5 \times (\text{Number of women in Professional Grades})$

Number of men in Professional Grades = $5 \times 90 = 450$ men.

Note (b) tells us the total number of staff (men + women) in both Professional and Managerial Grades is 1300.

Note (c) provides information about the total workforce, but Note (b) directly gives us the total staff specifically in Professional and Managerial Grades, which is what we need for this calculation. So, Note (c) is not required to answer this specific question.

Determining the Number of Men in Managerial Grades

We know the total staff in Professional and Managerial Grades is the sum of women and men in both categories:

Total Staff (Professional & Managerial) = Women (Professional) + Men (Professional) + Women (Managerial) + Men (Managerial)

We have the following values:

• Total Staff (Professional & Managerial) = $1300$ (from Note b)
• Women (Professional) = $90$ (calculated from table)
• Men (Professional) = $450$ (calculated using Note a)
• Women (Managerial) = $30$ (calculated from table)
• Men (Managerial) = ? (this is what we need to find)

Let's plug the known values into the equation:

$1300 = 90 + 450 + 30 + \text{Men (Managerial)}$

$1300 = (90 + 450 + 30) + \text{Men (Managerial)}$

$1300 = 570 + \text{Men (Managerial)}$

Now, solve for Men (Managerial):

$\text{Men (Managerial)} = 1300 - 570$

$\text{Men (Managerial)} = 730$

Therefore, there are 730 men in Managerial Grades.

Additional Information: Data Interpretation Concepts

Data interpretation questions often require you to extract information from tables or charts and use additional notes or conditions to perform calculations. It's important to carefully read all the given information and identify which pieces are relevant to the specific question being asked. In this case, understanding the total staff count in the relevant grades (Professional and Managerial) was key, as provided by Note (b). While Note (c) gives a percentage of the total workforce, Note (b) gives the direct count for the Professional and Managerial grades, making it more useful here.

Break down the problem into smaller steps:

• Identify the known values from the table and notes.
• Determine what value needs to be calculated.
• Set up the appropriate equations or formulas based on the relationships given in the notes.
• Perform the calculations step-by-step to arrive at the solution.

Always double-check your sums and calculations to avoid errors.
