Question: How many students passed in first class?
I. 85% of the students who appeared in the examination have passed either in first class or in second class or in pass class.
II. 750 students have passed in the second class.
III. The number of students who passed in pass class is 28% of those passed in the second class.
Solution:
To find out the number of students who passed in the first class, we need to analyze all the given statements.
Statement I: 85% of the students who appeared in the examination have passed either in first class or in second class or in pass class.
This statement gives us information about the percentage of students who have passed in the examination, but it doesn't give us any specific number for the students who passed in the first class.
Statement II: 750 students have passed in the second class.
This statement gives us the number of students who passed in the second class, but it doesn't give us any information about the number of students who passed in the first class.
Statement III: The number of students who passed in the pass class is 28% of those passed in the second class.
This statement gives us information about the number of students who passed in the pass class, but it doesn't give us any information about the number of students who passed in the first class.
Therefore, we cannot answer the question with the given information in all three statements, and option D is the correct answer.
Conclusion:
To answer the given question, we need to have specific information about the number of students who passed in the first class, which is not provided in any of the given statements. Hence, we cannot answer the question with the given information in all three statements.
