Answer : 3. "6000"
Explanation :

Let's denote the total number of students who appeared in the examination as 𝑥x.

Given that 92% of the students passed, it means 8% failed because the total percentage is 100%.

We can set up the equation:

8% of 𝑥=4808% of x=480

To find 8% of 𝑥x, we multiply 𝑥x by 81001008 (which is the same as multiplying by 0.08):

0.08𝑥=4800.08x=480

Now, we can solve for 𝑥x:

𝑥=4800.08x=0.08480𝑥=6000x=6000

So, 6000 students appeared in the examination.
