Detailed Solution

In a class, there are above average, below average and average students. Consider a class of 48 students. If 1 6  of students are above average and 1 4   of students are average, then the number of below average students are 28.
Total number of students = 48
Number of above average students = 1 6 ×48=8  
Number of average students = 1 4 ×48=12  
Total number of students = Number of above average students + Number of average students + Number of below average students
i.e., 48=8+12+  Number of below average students
Then, below average students = 48812=28  .
Therefore, there are 28 below average students in that class.
