In a certain school, the number of students in each section was 24. After admitting some students, three new sections have been started and now there are 16 sections with 21 students in each. What is the number of newly admitted students?
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
