Question
In a class 30% students passed in economics, and 40% passed in accountancy. And 22% passed in both accounts and economics. How much % of students failed in both the subjects?
Solution
To find the percentage of students who failed in both subjects, we first need to find the percentage of students who passed in at least one of the subjects.
-
We know that 30% of students passed in economics and 40% passed in accountancy. If we simply add these two percentages, we get 70%.
-
However, this would count the students who passed in both subjects twice. Since 22% of students passed in both subjects, we need to subtract this percentage from our total.
-
So, 70% - 22% = 48% of students passed in at least one of the subjects.
-
Since this is out of a total of 100%, the percentage of students who failed in both subjects is 100% - 48% = 52%.
So, 52% of students failed in both subjects.
