You can solve this problem using proportions.
If you had 20% of all particpants and 200 taking it, you can set up your proportion like this:

x 20
---- = ------
200 100
The 20/100 represents the percent.
Cross multiply
100x = 20 x 200
Divide by 100 to get x alone.
100x/100 = 200 x 20/100
You would get 40 people who will fail the exam.

To find out who will pass the exam, you simply subtract 200-40 and you would get 160 people will pass the test.
