Answer:
The average mark of the remaining students = 90.98
Step-by-step explanation:
Let the total number of students be x then the number of each group of students are :
Genius = 28% of x = 0.28x
Slow = 27% of x = 0.27x
Others = x - (0.27x + 0.28x) = 0.45x
The total marks for all the students = 75 × x = 75x
The total marks for each group is given by :
Genius = 0.28x × 85 = 23.8x
Slow = 0.27x × 38 = 10.26x
Others = 75x - (23.8x + 10.26x)
= 40.94x
The total marks for the remaining students = 40.94x
The total remaining students = 0.45x
The average mark of the remaking students = 40.94x/0.45x = 90.98
The average mark of the other students is 90.98
