Calculating Total Students Across All Departments

The question asks for the total number of students in all the Departments of the Institute, based on the provided table. To find the total number of students, we need to sum the total number of students from each department listed in the table.

Let's look at the table and identify the 'Total No. of Students' for each department:

We need to add the numbers from the 'Total No. of Students' column for all departments.

Step-by-Step Calculation of Total Students

• Total students in Computer Department: 840
• Total students in Civil Department: 220
• Total students in Mechanical Department: 900
• Total students in Electrical Department: 360
• Total students in Electronics Department: 450
• Total students in Mining Department: 540

Summing these values gives the total number of students:

Total Students = 840 + 220 + 900 + 360 + 450 + 540

Let's perform the addition:

\(840 + 220 = 1060\)
\(1060 + 900 = 1960\)
\(1960 + 360 = 2320\)
\(2320 + 450 = 2770\)
\(2770 + 540 = 3310\)

So, the total number of students in all the Departments is 3310.

Comparing this result with the given options:

• Option 1: 2210
• Option 2: 3210
• Option 3: 3400
• Option 4: 3310

The calculated total number of students, 3310, matches Option 4.

Additional Information: Understanding Data Tables

Data tables like the one provided are useful for organizing information clearly. Each row typically represents an entity (like a department), and each column represents an attribute of that entity (like total students, percentage of females, percentage of males).

To answer questions based on a table, it's important to:

• Read the table headings carefully to understand what each column and row represents.
• Identify the specific data needed to answer the question. In this case, only the 'Total No. of Students' column was needed.
• Perform the required calculation or analysis using the identified data.

While the table also provided percentages of females and males, these were extra details not necessary for finding the overall total number of students. Questions might ask for other calculations, such as the number of female students in a specific department (which would require using the percentage and the total number of students) or the average number of students per department.
