Answer: 28 students are below average
Step-by-step explanation:
Now we know that 1/6 of the class students are above average and 1/4 are average and rest are below average.
We also know that there are 48 people in the class.
And we have to find teh number of people who are below average.
But first lets find out the people who are above average :
= 1/6 x 48
= 8
= So 8 students out of 48 are below average.
Now lets find out students who are average :
= 1/4 x 48
=12
= so 12 students are average
Now we know that rest are below average
So Students who are below average are 48-(12 + 8)
48-20
=28
Therefore 28 students are below average
