General Logical Reasoning and Puzzles 2 — Questions and Answers
Question 1: All doctors are professionals. Some professionals are wealthy. Which conclusion must be true?
- All doctors are wealthy
- Some doctors are wealthy
- No doctors are wealthy
- Some doctors may be wealthy (Correct answer)
Correct answer: Some doctors may be wealthy
The premises only guarantee that some professionals are wealthy, but don't confirm any doctors fall in that subset.
Question 2: A train leaves Chicago at 8 AM traveling east at 60 mph. Another leaves New York at 9 AM traveling west at 80 mph. The cities are 790 miles apart. Where do they meet?
- 360 miles from Chicago (Correct answer)
- 420 miles from Chicago
- 430 miles from Chicago
- 390 miles from Chicago
Correct answer: 360 miles from Chicago
After 1 hour the first train is 60 miles out; remaining 730 miles close at 140 mph (≈5.21 hrs), putting meeting point at 60+5.21×60≈373 miles — closest answer is 360 miles from Chicago.
Question 3: If PENCIL is coded as RGPEKN, what is the code for PAPER?
- RCRGT
- RCRGT (Correct answer)
- QBQFS
- RCQGT
Correct answer: RCRGT
Each letter shifts +2 positions in the alphabet: P→R, A→C, P→R, E→G, R→T giving RCRGT.
Question 4: Which number replaces the question mark? 3, 6, 11, 18, 27, ?
- 36
- 38
- 40 (Correct answer)
- 38
Correct answer: 40
Differences are 3, 5, 7, 9, 11 — an arithmetic sequence of odd numbers — so 27+13=40.
Question 5: In a row of 10 students, Mia is 4th from the left and 7th from the right. How many students are in the row?
- 9
- 10 (Correct answer)
- 11
- 12
Correct answer: 10
Position from left + position from right − 1 = total: 4+7−1=10.
Question 6: Six friends sit in a circle. Ana is directly opposite Ben. Carlos sits two seats left of Ana. Who is directly opposite Carlos?
- The person two seats right of Ben (Correct answer)
- Ana
- Ben
- The person two seats left of Ben
Correct answer: The person two seats right of Ben
In a 6-person circle, opposite seats are 3 apart; Carlos is 2 left of Ana, so his opposite is 3 seats from Carlos, which is 2 seats right of Ben.
Question 7: A clock shows 3:15. What is the angle between the hour and minute hands?
- 0°
- 7.5° (Correct answer)
- 15°
- 22.5°
Correct answer: 7.5°
At 3:15, the minute hand is at 90° and the hour hand has moved 3×30°+15×0.5°=97.5°, giving a difference of 7.5°.
