Answer:

54

Step-by-step explanation:

First, take the number 200. we can remove 20, because they didn't go to the exams.

Secondly, we have to find 70% of 180. This can be done by doing some math.

Let's do this by using fractions. 70/100 * 180 = 126.

Third, we find the other 30% by doing the same equation.

30/100 * 180 = 54

(This is the part where you thank me, and give your opinions, and maybe "brainliest" answer. :D)

I don’t know the step by Step of the math but I’m pretty sure it’s 54. I say pretty sure because I know it’s either 74 or 54 but I’m not sure which. I’m more confident in 54 tho
