The number of teaching males in College D is 46. If 124 males from college A of whom 62 are non-teaching, are transferred to college D. then the new number of non-teaching males in college D is.

The correct answer is

158

Analyzing Employee Data and Transfers in Colleges

The question asks us to determine the new number of non-teaching males in College D after a transfer of employees from College A. We are given a table with employee data for four colleges and additional specific information about College D and the transfer.

Initial Data for College D

Based on the provided table and the information given in the question:

  • Total employees in College D: 224
  • Male employees in College D: 142
  • Teaching males in College D: 46 (This value is given in the question statement, not directly from the table).

Calculating Initial Non-Teaching Males in College D

The total number of male employees is divided into teaching males and non-teaching males. Therefore, we can find the initial number of non-teaching males in College D by subtracting the number of teaching males from the total number of male employees.

Initial Non-Teaching Males (D) = Total Male Employees (D) - Teaching Males (D)

Initial Non-Teaching Males (D) = $142 - 46$

Initial Non-Teaching Males (D) = $96$

So, initially, there are 96 non-teaching male employees in College D.

Understanding the Transfer from College A to College D

The question states that 124 males from College A are transferred to College D. Out of these 124 transferred males, 62 are non-teaching employees.

  • Total males transferred: 124
  • Non-teaching males transferred: 62

Calculating the New Number of Non-Teaching Males in College D

To find the new number of non-teaching males in College D, we need to add the non-teaching males who were transferred from College A to the initial number of non-teaching males in College D.

New Non-Teaching Males (D) = Initial Non-Teaching Males (D) + Non-Teaching Males transferred from A

New Non-Teaching Males (D) = $96 + 62$

New Non-Teaching Males (D) = $158$

After the transfer, the new number of non-teaching males in College D is 158.

Summary of Calculations

Metric Value Calculation/Source
Initial Male Employees (D) 142 From Table
Teaching Males (D) 46 Given in Question
Initial Non-Teaching Males (D) 96 142 - 46
Males Transferred (A to D) 124 Given in Question
Non-Teaching Males Transferred (A to D) 62 Given in Question
New Non-Teaching Males (D) 158 96 + 62

Therefore, the new number of non-teaching males in college D is 158.

Revision Table: College Employee Data Analysis

It's helpful to review the categories of employees when working with such tables:

  • Total Employees = Male Employees + Female Employees
  • Male Employees = Teaching Males + Non-Teaching Males
  • Female Employees = Teaching Females + Non-Teaching Females
  • Total Employees = Teaching Males + Non-Teaching Males + Teaching Females + Non-Teaching Females

Understanding these basic relationships is crucial for filling in missing values or performing calculations based on the table.

Additional Information: Handling Data Transfers

When dealing with transfers of employees between departments or colleges, remember to track how the transfer affects specific categories. In this case, the transfer of males was broken down into teaching and non-teaching, which allowed us to specifically update the non-teaching male count in the destination college (College D).

  • Identify the specific category affected by the transfer (e.g., males, females, teaching, non-teaching).
  • Determine the number of employees in that specific category being transferred.
  • Add or subtract the transferred number from the initial count in the relevant category of the destination or source location.
  • Ensure you only use the part of the transfer relevant to the specific question being asked (here, only the non-teaching males transferred).
