Total 12 members * Rs. 8 = Rs. 96/-.
If total becomes 8 members (since 4 of them left) * (Rs. 8+extra Rs4/-) = Rs. 96/-.
If total becomes 8 members (since 4 of them left) * (Rs. 8+extra Rs4/-) = Rs. 96/-.

I agree with your answers.
In my point of view.
Total investment =96,
Amount divided per head =4,
T. A=96/4=24.
4 people don't participated=4*4=16,
Since 24-16=8.
Can we apply this method?

Let x bw no of students.
4 absent--> (x-4) students
each student spends rs 4 extra ---> (x-4)*4 for total amount 96rs ---->> (x-4)*4=96 --->> x=28rs.
4 absent.
Hence, 4rs extra ----> 4*4=16rs ------->> x=24-16=12 rs for each who attended.
Now 96/12= 8 students.
4 absent--> (x-4) students
each student spends rs 4 extra ---> (x-4)*4 for total amount 96rs ---->> (x-4)*4=96 --->> x=28rs.
4 absent.
Hence, 4rs extra ----> 4*4=16rs ------->> x=24-16=12 rs for each who attended.
Now 96/12= 8 students.

let x be the total no.of. friends. Let each of them had to pay Rs.y for getting a sum 96.
Therefore, x*y=96.
But four of them didn't turn up, so now the number of friends are x-4.
Remaining ones contributed Rs. 4 each extra. So now each of them has to pay y+4.
Therefore, (x-4)*(y+4)=96.
Solving these 2 equations, you will get x=12.
But four of them didn't turn up, so now the number of friends are x-4=12-4=8.
Therefore, x*y=96.

Every person to spend 4/- then extra 4/- expended then also total value of amount is 8/- for each person.
