Calculating Average Semester Fees Difference

The question asks for the difference between the average semester fees of BCA and MCA courses over the years 2016 to 2020, based on the provided table.

First, let's look at the given data in the table:

To find the average semester fees for BCA over the years 2016-2020, we need to sum the BCA fees for each year and divide by the number of years, which is 5.

Total BCA Fees (2016-2020) $= 25000 + 26500 + 27200 + 27600 + 28000 = 134300$

Average BCA Fees $= \frac{\text{Total BCA Fees}}{\text{Number of Years}}$

Average BCA Fees $= \frac{134300}{5} = 26860$

Next, we calculate the average semester fees for MCA over the same period (2016-2020). We sum the MCA fees for each year and divide by 5.

Total MCA Fees (2016-2020) $= 52000 + 53500 + 54200 + 55700 + 56800 = 272200$

Average MCA Fees $= \frac{\text{Total MCA Fees}}{\text{Number of Years}}$

Average MCA Fees $= \frac{272200}{5} = 54440$

Finally, we need to find the difference between the average semester fees of BCA and the average semester fees of MCA.

Difference $= \text{Average MCA Fees} - \text{Average BCA Fees}

Difference $= 54440 - 26860 = 27580$

The difference between the average semester fees of BCA and average semester fees of MCA during 2016-2020 is 27580.

Additional Information: Understanding Averages and Data Analysis

An average (specifically, the arithmetic mean) is calculated by summing a set of values and dividing by the number of values. In this problem, we used the average to get a single representative value for the semester fees of each course over a five-year period. Calculating the difference between these averages helps us compare the typical fee structure of two different courses over the same duration. Data analysis often involves calculating averages, differences, percentages, and other metrics to understand trends and make comparisons from tables or datasets.

• The average provides a central value for a dataset.
• Comparing averages helps in understanding the general difference between two groups or categories.
• This type of question tests your ability to extract data from a table and perform basic arithmetic calculations.
