8. Explain how will you find sum of each row and each column of a given table having 2

columns and 10 rows.

Ans: Let's break down the process of finding the sum of each row and each column in a table

with 2 columns and 10 rows, considering an information technology context. We'll simplify

the explanation step by step.

Understanding the Table:

Imagine you have a table with 2 columns and 10 rows, like this:

Easy2Siksha

• Each row represents some information related to information technology, and each

column represents different metrics or aspects of that information.

Finding the Sum of Each Row:

Understanding Row Sum:

To find the sum of each row, we want to add up all the values in each row.

Select a Row:

Start with the first row (Row 1) and move row by row until you reach the last row (Row 10).

Add Values in the Row:

For each row, add up the values in Column 2.

• Summing up the values in each row gives you the sum of that row.

Example Calculation:

Let's take an example. If the values in Column 2 for Rows 1 to 10 are 10, 20, 30, ..., 100, then

the sum for Row 1 would be 10, for Row 2 it would be 20, and so on.

• These sums represent the total values for each respective row.

Finding the Sum of Each Column:

Understanding Column Sum:

To find the sum of each column, we want to add up all the values in each column.

Select a Column:

Start with the first column (Column 1) and move column by column until you reach the last

column (Column 2).

Add Values in the Column:

For each column, add up the values in all the rows.

• Summing up the values in each column gives you the sum of that column.

Example Calculation:

Continuing with the previous example, if the values in Column 2 for Rows 1 to 10 are 10, 20,

30, ..., 100, then the sum for Column 2 would be the sum of these values.

• These sums represent the total values for each respective column.

Implementation in Information Technology:

In an information technology context, such a table might represent various IT metrics for

different scenarios. Let's consider a scenario where Column 1 represents different IT

parameters, and Column 2 represents the corresponding numerical values.

Example IT Table:

Suppose you have an IT table like this:

Easy2Siksha

• Here, each row represents a different IT parameter, and the corresponding values

are in Column 2.

Finding Row Sums:

To find the sum for each row, you'd simply add up the values in Column 2 for each

parameter.

These sums provide a total for each IT parameter.

Finding Column Sums:

To find the sum for each column, you'd add up all the values in each column.

• These sums give you an overall view of IT parameters and their corresponding

values.

Practical Implementation:

In a practical scenario, you might use a spreadsheet tool like Microsoft Excel or Google

Sheets to manage and analyze such data. Here's how you could do it in a spreadsheet:

Enter Data:

Enter your IT metrics data into the spreadsheet with two columns: one for IT parameters

and another for values.

Use SUM Function for Rows:

For each row, use the SUM function to add up the values in the corresponding column.

=SUM(B2:B11) // Assuming your values are in Column B (B2 to B11 for Rows 1 to 10)

• Drag this formula down for each row.

Easy2Siksha

Use SUM Function for Columns:

For each column, use the SUM function to add up all the values in that column.

=SUM(B2:B11) // Assuming your values are in Column B

• Place this formula at the bottom of the column.

Viewing Results:

You'll now see the sum for each row and each column, providing a clear summary of your IT

metrics.

Conclusion:

In summary, finding the sum of each row and each column in a table involves adding up

values either horizontally (for rows) or vertically (for columns). In an information technology

context, this process helps analyze and understand the total impact or performance metrics

associated with different IT parameters. Practical tools like spreadsheets make this task

efficient and provide a clear overview of the data, aiding in decision-making processes

within the realm of information technology.
