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.
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.

The correct answer is option A. 8.
The question asked for people who finally attended the picnic.
Initially, there were 12 members. And 4 of them backed.
So, 12 - 4 = 8.
Checking whether it is correct,
96/12 = 8rs per member
12-4 = 8 people remaining
Then one should add Rs.4
So, 8 + 4 = 12rs per person should be added. 12 * 8 = 96.

Let, the number of friends are 12, then 96/12=8 which is the control of each person, suddenly 4 of them turn up, now (12-4) = 8,
a number of friends left and contro increases by 4 which now becomes 12 and makes 12x8= 9.
Hence 8 is the wrong answer and 12 is the correct answer.

Hence 8 is the wrong answer and 12 is the correct answer.

Number of persons is x.
96/x-4 - 96/x = 4,
1/x-4 - 1/x = 4/96,
x-(x-4)/x(x-4) = 1/24,
The correct answer is 8.
x2 - 4x -96 = 0,
(x-12)(x+8) = 0,
The number of people can't be -ve.
So, x = 12.
Then Req number = x-4
=> x-12,
=>8.
Total numbers who attended the picnic was 8.
96/x-4 - 96/x = 4,
1/x-4 - 1/x = 4/96,
x-(x-4)/x(x-4) = 1/24,
The correct answer is 8.
x2 - 4x -96 = 0,
(x-12)(x+8) = 0,
The number of people can't be -ve.
So, x = 12.
Then Req number = x-4
=> x-12,
=>8.
Total numbers who attended the picnic was 8.
