In an Examination a candidate has to score minimum of 24 marks in order to clear the exam. The maximum that he can score is 40 marks. Identify the Valid Equivalence values if the student clears the exam

  1. 22, 23, 26

  2. 21, 39, 40

  3. 29, 30, 31

  4. 0, 15, 22

C Correct answer
Explanation

The valid equivalence class for passing the exam is scores from 24 to 40 (inclusive). Option C (29, 30, 31) contains only valid passing scores. Option A includes 22 and 23 which are failing. Option D includes 0, 15, and 22 which are all failing. Option B has 21 (failing) and 39, 40 (passing) - mixed classes.

AI explanation

To answer this question, we need to understand the given conditions. The candidate needs to score a minimum of 24 marks to clear the exam, and the maximum score possible is 40 marks.

Let's go through each option to determine if it contains valid equivalence values for the candidate to clear the exam:

Option A) 22, 23, 26

  • None of these values are equal to or greater than 24. Therefore, this option is incorrect.

Option B) 21, 39, 40

  • The values 39 and 40 are greater than 24, so they are valid equivalence values. However, the value 21 is less than 24, so it is not valid. Therefore, this option is incorrect.

Option C) 29, 30, 31

  • All of these values are equal to or greater than 24. Therefore, this option is correct.

Option D) 0, 15, 22

  • None of these values are equal to or greater than 24. Therefore, this option is incorrect.

Therefore, the valid equivalence values for the candidate to clear the exam are 29, 30, and 31. The correct answer is option C.
