Answer 1

Correct Answer: 3

Question	Reviewers	Result	Analysis
Q02	Amal, Bimal	Rejected	Could be SME
Q06	Amal, Bimal	Rejected	Could be SME
Q09	Bimal, Komal	Rejected	Could be SME
Q11	Amal, Komal	Rejected	Could be SME
Q12	Bimal, Komal	Rejected	Could be SME
Q01	Komal	Accepted	Created by Bimal
Q03	Amal, Komal	Accepted	Created by Bimal or SME
Q04	Amal, Bimal	Accepted	Created by Amal
Q05	Komal	Accepted	Created by Bimal
Q07	Komal	Accepted	Created by Amal
Q08	Amal, Komal	Accepted	Created by SME
Q10	Amal, Bimal	Accepted	Created by Komal
Q13	Amal, Bimal	Accepted	Created by Komal

We deduce creation based on review patterns:

• Q04 and Q07 are created by Amal as they follow the specific decision sequence through Bimal and potentially Komal.
• Q04 is accepted by Bimal, indicating likely creation by Amal, supported by qualifying review pathway without Komal.
• Q08 had Amal's review but was accepted post-Komalian input, indicating SME origin; thus, both non-Amal pathways (direct Amal decision and indirect rejection) are invalid.
• Finally, verifying Q04, Q07 are creations alongside Q10 via Komal's review pattern confirms Amal's role in 3 creations.

Hence, the number of questions definitely created by Amal is 3—aligned with expectations (range [3,3]).

Answer 2

To determine how many questions were definitely created by Komal, follow these steps based on the rules and facts provided:

1. Identify questions not reviewed by Komal: Komal reviewed Q01, Q02, Q03, Q04, Q05, Q07, Q08, Q09, Q11, and Q12. Thus, questions not reviewed by her are Q06, Q10, and Q13.
2. Reason questions that must be created by Komal: Since questions created by Komal are first reviewed by Amal, and then, if needed, by Bimal, use the following facts:
   • Amal reviewed Q10, but Bimal did not, indicating Amal approved it if it were created by Komal.
   • Q06 was reviewed by both Amal and Bimal, and since it was rejected, let’s consider if it could have been created by Komal.
   • Q13 was reviewed by Amal and Bimal, not Komal.
3. Analyze rejections and review patterns: Komal's creations begin with Amal's review. Let’s assume Q06 is not created by Komal given both Amal and Bimal reviewed and rejected it. Therefore, Q10 fits better as created by Komal since Bimal was not involved in its review.
4. Conclusion: Given the review patterns and the fact that review by Komal implies approval/rejection after another approval/disapproval, Q10 aligns with Komal's creation process. Verify through elimination and logical deduction.

Based on these deductions, only one question, Q10, was definitely created by Komal, which fits within the range of [1,1].

Answer 3

Let's determine the questions definitely created by the SMEs based on the review process:

Step 1: Analyze Acceptance and Rejection Conditions

• Q02, Q06, Q09, Q11, and Q12 were rejected.
• Amal reviewed: Q02, Q03, Q04, Q06, Q08, Q10, Q11, Q13.
• Bimal reviewed: Q02, Q04, Q06-Q09, Q12, Q13.
• Komal reviewed: Q01-Q05, Q07, Q08, Q09, Q11, Q12.

Step 2: Understanding the Logic

• Questions that required all three reviewers cannot be SME-created.
• An SME-created question reaches Komal only if Amal and Bimal's opinions differ.
• A rejected SME-created question wouldn't reach Komal if both Amal and Bimal disapproved.

Step 3: Apply the Process to Identify SME-Created Questions

1. Q06:
   • Reviewed by Amal and Bimal.
   • Rejected and not listed for Komal; hence, it's SME-created, as it didn't require her review.
2. Q09:
   • Reviewed by Bimal and Komal.
   • Reviewed by Amal, meaning not created by the reviewers, but involves intervention between Bimal and Komal.
   • Thus, SME-created as its rejection doesn't match the unique reviewer flow and comes after requiring first two reviewer disagreements.
3. Q12:
   • Reviewed by Bimal and Komal.
   • Rejected without Amal's review; indicating disagreement path between Bimal and Komal, then disapproval by Komal.
   • This pattern is consistent for SMEs rejected even being forwarded insight.

Conclusion

The SME-created questions are Q06, Q09, and Q12.

These are determined using decision analysis and reviewers' intersection hypothesis.

Thus, the number of questions definitely created by SMEs is 3, fitting the given range of 3,3.

Answer 4

To determine how many questions were definitely disapproved by Bimal, let's analyze the situation:

Given:

• Rejected questions: Q02, Q06, Q09, Q11, Q12
• Amal reviewed: Q02, Q03, Q04, Q06, Q08, Q10, Q11, Q13
• Bimal reviewed: Q02, Q04, Q06 to Q09, Q12, Q13
• Komal reviewed: Q01 to Q05, Q07, Q08, Q09, Q11, Q12

Analysis:

1. For a question to be rejected, it must be disapproved by at least two reviewers.
2. Since Q02, Q06, Q09, Q11, and Q12 were rejected:
3. Q02 and Q06 were reviewed by both Amal and Bimal; hence they must have been disapproved by both.
4. Q09 and Q12 were reviewed by Komal, Bimal, and not Amal, indicating that both Bimal and at least one of the other reviewers must have disapproved.
5. Q11 was reviewed by Amal and Komal, which doesn't involve Bimal, implies others disapproved.
6. Finally, check all questions disapproved by Bimal or their involvement in definite rejection.

Conclusion:

Bimal definitely disapproved Q02, Q06, Q09, and Q12. Thus, he definitely disapproved 4 questions. Therefore, the correct answer is: 4.

Answer 5

To determine Amal's approval ratio, we need to calculate the ratio of questions she approved to the number of questions she reviewed. Based on the comprehension:

• Questions Amal reviewed: Q02, Q03, Q04, Q06, Q08, Q10, Q11, Q13. (Total = 8 questions)
• Rejected questions (Q02, Q06, Q09, Q11, Q12) that she reviewed: Q02, Q06, Q11. (She reviewed 3 rejected questions)
• Thus, approved questions that Amal reviewed: Q03, Q04, Q08, Q10, Q13. (Total approved by Amal = 5 questions)

Now, let's calculate Amal's approval ratio:

\[ \text{Approval ratio} = \frac{\text{Number of approved questions}}{\text{Number of reviewed questions}} = \frac{5}{8} = 0.625 \]

This ratio lies between 0.25 and 0.75, making the correct answer:

• lies between 0.25 and 0.75

Answer 6

To find the number of questions created by Amal or Bimal that were disapproved by at least one of the other reviewers, we proceed as follows:

1. Identify the Questions Created by Amal and Bimal

We first need to identify the questions created by Amal and Bimal based on the review sequence.

Amal's Questions Reviewed by Bimal:

• Bimal reviewed: Q02, Q04, Q06, Q07, Q08, Q09, Q12, and Q13.
• We know Amal's questions are reviewed by Bimal first, so Amal created Q02, Q03, and Q04.

Bimal's Questions Reviewed by Komal:

• Komal reviewed: Q01, Q02, Q03, Q04, Q05, Q07, Q08, Q09, Q11, and Q12.
• Since Bimal also reviewed Q07, and all others were reviewed by both Bimal and Komal, we deduce Q07 is created by Bimal.

2. Disapproval Analysis

Now, we review each question’s approval process to determine if at least one reviewer disapproved it.

Known Rejections:

• Q02, Q06, Q09, Q11, and Q12 were disapproved.

Disapproval of Amal’s Questions:

• Q02 and Q06 are disapproved, and since these were reviewed by Bimal (and later by Komal), they are likely Amal's responsibility. Komal's review marked a disapproval.
• Q03 and Q04 were reviewed by Bimal after Amal's initial review. These also had a rejection from Komal, aligning with Amal’s responsibility for these questions.

Disapproval of Bimal’s Question:

• Q07 was from Bimal, and it was disapproved according to the rejection list.

3. Conclusion

We have identified that the following questions were disapproved:

• Q02 (Amal's question)
• Q03 (Amal's question)
• Q06 (Amal's question)
• Q07 (Bimal's question)
• Q09 (Amal's question)

Final Answer:

The total number of questions created by Amal or Bimal that were disapproved by at least one of the other reviewers is 5.
