Question

Group of students have Average Score of 75 in that 28% Genius student scored Average 85 and Slow students that are 27% in number Scored Average of 38 what is the Score of Remaining Students.?​

Answer 1

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
