The average of the marks obtained in a class with 20 students has been 6. Eight students have suspended with a 3 and the rest have exceeded 5.

What has been the average grade of the approved students?


If 8 students have scored a 3, to compensate for this grade in the total average, it means that 8 students have scored a 9.
The other 4 students will have taken a 6, it is the only way to get an average of 6.
So, if 8 students have taken a 9 and 4 students have taken a 6, the average will be 8.
