Mettl Logical Reasoning and Puzzles 3 — Questions and Answers
Question 1: Some doctors are teachers. All teachers are graduates. Conclusion I: Some doctors are graduates. Conclusion II: All graduates are doctors. Which is correct?
- Only Conclusion I follows (Correct answer)
- Only Conclusion II follows
- Both conclusions follow
- Neither conclusion follows

Some doctors are teachers and all teachers are graduates, so some doctors must be graduates; the converse 'all graduates are doctors' is not implied.
Question 2: In a code: '247' = 'spread red carpet', '256' = 'dust your carpet', '264' = 'dust wet carpet'. Which digit represents 'your'?
- 2
- 5 (Correct answer)
- 6
- 4
Correct answer: 5
Digit 2 = carpet (common to all three), digit 6 = dust (common to 256 and 264), so digit 5 = your (unique to 256).
Question 3: Pointing to a photo, Ravi says, 'His mother is the only daughter of my mother.' How is Ravi related to the person in the photo?
- Uncle
- Father
- Brother
- Maternal Uncle (Correct answer)
Correct answer: Maternal Uncle
The only daughter of Ravi's mother is Ravi's sister; the photo shows her son, making Ravi his maternal uncle.
Question 4: A is older than B. C is older than A. D is older than C but younger than E. Who is the youngest?
- A
- B (Correct answer)
- C
- D
Correct answer: B
The order from oldest to youngest is E > D > C > A > B, so B is youngest.

Correct answer: 250
144, 169, 196, and 225 are perfect squares (12², 13², 14², 15²); 250 is not a perfect square.
Question 6: If the day before yesterday was Saturday, what day will it be the day after tomorrow?
