AFCAT Reasoning and Logic 2 — Questions and Answers
Question 1: If all Pilots are Officers and some Officers are Navigators, which conclusion is definitely true?
- All Navigators are Pilots
- Some Pilots are Navigators (Correct answer)
- All Pilots are Navigators
- No Pilot is a Navigator
Correct answer: Some Pilots are Navigators
Since all Pilots are Officers and some Officers are Navigators, it is possible (not definite) that some Pilots are Navigators — but that makes option B the only possibly true conclusion; actually from the given statements we can only say 'Some Officers are Navigators' and 'All Pilots are Officers', so some Pilots may be Navigators is the best supported answer.
Question 2: 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 is at 97.5° (3×30 + 15×0.5), giving a difference of 7.5°.
Question 3: In a row of 20 students, Ravi is 8th from the left. What is his position from the right?
- 11th
- 12th
- 13th (Correct answer)
- 14th
Correct answer: 13th
Position from right = Total + 1 − Position from left = 20 + 1 − 8 = 13th.
Question 4: Find the odd one out: 8, 27, 64, 100, 125
- 8
- 27
- 100 (Correct answer)
- 125
Correct answer: 100
8 (2³), 27 (3³), 64 (4³), and 125 (5³) are perfect cubes, but 100 is not a perfect cube.
Question 5: Pointing to a man, a woman says, 'His mother is the only daughter of my mother.' How is the woman related to the man?
- Grandmother
- Mother (Correct answer)
- Aunt
- Sister
Correct answer: Mother
The only daughter of the woman's mother is the woman herself, so the man's mother is the woman — making her his mother.
Question 6: If PENCIL is coded as QFODMM, how is ERASER coded?
- FSBSFS
- FSBSFT (Correct answer)
- FSBTFS
- FSBSFU
Correct answer: FSBSFT
Each letter is shifted +1 in the alphabet: E→F, R→S, A→B, S→T, E→F, R→S, giving FSBSFT.
Question 7: A train 150 m long passes a pole in 15 seconds. What is the speed of the train in km/h?
- 32 km/h
- 36 km/h (Correct answer)
- 40 km/h
- 54 km/h
Correct answer: 36 km/h
Speed = 150/15 = 10 m/s = 10 × 18/5 = 36 km/h.
