For College B in the year 2021, if 20% of students were enrolled in B.Sc; 30% of students were enrolled in B.Com. and the remaining students were enrolled in BCA, then what is the difference between the number of students enrolled in BCA and B.Sc?
Correct Answer :
240
Solution :
The correct option is 240.
Let's solve this step-by-step to understand how we arrive at this answer.
Step 1: Extract the relevant data from the table
From the table, we locate the row for the year 2021 and the column for College B.
The number of students enrolled in College B in the year 2021 is 800.
Step 2: Determine the percentage distribution of students in College B in 2021
According to the question, the distribution of students is as follows:
- Enrolled in B.Sc: 20%
- Enrolled in B.Com: 30%
- Enrolled in BCA: Remaining percentage
First, let's find the percentage of students enrolled in BCA:
Step 3: Calculate the difference in percentage between BCA and B.Sc
We need to find the difference between the number of students enrolled in BCA and B.Sc.
We can first find the difference in their percentage shares:
Step 4: Calculate the absolute difference in the number of students
Now, we calculate 30% of the total number of students enrolled in College B in 2021 (which is 800):
Thus, the difference between the number of students enrolled in BCA and B.Sc is 240.
