The question asks us to find the difference between the total semester fees for all courses in the year 2018 and the total semester fees for all courses in the year 2019. To do this, we first need to calculate the total fees for each of these years by summing up the fees for all the listed courses (BCA, MCA, MTech, MPhil) for that specific year, using the data provided in the table.

Calculating Total Semester Fees Per Year

Let's calculate the total semester fees for all courses for the years 2018 and 2019 separately.

Total Semester Fees in 2018

To find the total semester fees in 2018, we add the fees for BCA, MCA, MTech, and MPhil in 2018:

• BCA fee in 2018 = 27200
• MCA fee in 2018 = 54200
• MTech fee in 2018 = 62500
• MPhil fee in 2018 = 32600

Total fees in 2018 \(=\) Fee(BCA, 2018) \(+\) Fee(MCA, 2018) \(+\) Fee(MTech, 2018) \(+\) Fee(MPhil, 2018)

Total fees in 2018 \(=\) \(27200 + 54200 + 62500 + 32600\)

Total fees in 2018 \(=\) \(176500\)

Total Semester Fees in 2019

Similarly, to find the total semester fees in 2019, we add the fees for BCA, MCA, MTech, and MPhil in 2019:

• BCA fee in 2019 = 27600
• MCA fee in 2019 = 55700
• MTech fee in 2019 = 62900
• MPhil fee in 2019 = 33400

Total fees in 2019 \(=\) Fee(BCA, 2019) \(+\) Fee(MCA, 2019) \(+\) Fee(MTech, 2019) \(+\) Fee(MPhil, 2019)

Total fees in 2019 \(=\) \(27600 + 55700 + 62900 + 33400\)

Total fees in 2019 \(=\) \(179600\)

Finding the Difference in Total Fees

Now, we need to find the difference between the total semester fees of 2018 and 2019. The difference is calculated by subtracting the total fees of 2018 from the total fees of 2019.

Difference \(=\) Total fees in 2019 \(-\) Total fees in 2018

Difference \(=\) \(179600 - 176500\)

Difference \(=\) \(3100\)

The difference between the total semester fees (for all courses) of 2018 and 2019 is 3100.

Revision Table: Key Fee Data

Here is a summary of the total fees calculated:

Additional Information: Understanding Fee Tables

Data tables like the one presented are common in quantitative reasoning questions. They organize information clearly by categories (like Years and Courses) and values (like Fees). To answer questions based on such tables, it's important to carefully read the rows and columns to find the relevant data points. When asked for a total across different categories for a specific year, you sum the values in that year's row. When asked for a difference between years, you calculate the totals for each year and then subtract one from the other. Pay close attention to which years and courses are specified in the question.
