Answer:
4
Step-by-step explanation:
The computation is shown below:
Given that
There are total number of students i.e. 48
The ratio at present is 4:1
Now the computer needed to make the ratio be 3:1
So let us assume the number of students be 4x
And, the number of computers be x
So the 4x = 48
x = 12
So the computer be 12
Now the new ratio is 3:1
Students be 3x
And, computers be x
So
3x = 48
x = 16
Now the more computer needed is
= 16 - 12
= 4
hence, this is the answer but the same is not provided in the given options
