Explanation
Step 1: Calculate the initial number of sections.
Total current sections =16.
Since 3 new sections were added, initial sections =16−3=13.
Step 2: Calculate the initial total number of students.
Initial students =Initial sections×Initial students per section
Initial students =13×24=312.
Step 3: Calculate the current total number of students.
Current students =Current sections×Current students per section
Current students =16×21=336.
Step 4: Calculate the number of new students.
Newly admitted students =Current students−Initial students
Newly admitted students =336−312=24.
Correct Option: 2
