Question
In a class, 15% of total number of students failed in Science, 5% of total number of students failed in Maths and 10% of total number of students failed in both.How much percentage of students passed in both Maths and Science?Options89%50%70%47%
Solution
To solve this problem, we need to add the percentages of students who failed in Science and Maths, and then subtract the percentage of students who failed in both, because they were counted twice in the first step.
Here's the step-by-step calculation:
- Add the percentage of students who failed in Science and Maths: 15% + 5% = 20%
- Subtract the percentage of students who failed in both subjects, because they were counted twice in the first step: 20% - 10% = 10%
- Since the total percentage of students is 100%, the percentage of students who passed in both subjects is: 100% - 10% = 90%
So, the correct answer is 90%, which is not listed in the options. There might be a mistake in the options provided.
