Question

Choose the inference that can be inferred from the given statement by selecting the right option.
Statement:
Out of 1200 students who have appeared for the exam, \(30\%\) of them got more than \(80\%\) of the marks and rest all scored below \(40\%\), while the pass mark in the exam was \(50\%\).
Inferences:
I. None of the students scored marks in the range \(40\%-80\%\) 
II. Most of the students have not performed well in the exam

• A. Only inference I follows
• B. Only inference II follows
• C. Both inferences I and II follow
• D. Neither inference I nor inference II follows

Answer 1

The Correct Option is C

Step 1: Analyze the statement 

The statement clearly states that 30% of students scored more than 80%, and the rest scored below 40%.

Step 2: Evaluate the score range

This implies that no students scored in the range 40%-80%, making inference I correct.

Step 3: Evaluate overall performance

Since the majority of students scored below 40%, most students have not performed well, making inference II correct as well.

Step 4: Conclusion

Thus, the correct answer is Both inferences I and II follow.
