In a class total students are 200, 180 appeared in exams 70% qualified. how many students failed in exam.

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
