In a class, 15% of total number of students failed in Science, 25% 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?
Answer & explanation
Correct answer: option 2
According to the given information in the question, the above diagram is formed:
Total number of students = 100%
Total number of students who failed in either 1 or both the subjects = 30%
Thus, total number of students who passed = 70% i.e. (100% - 30%)
