ASET Logical Reasoning 1 — Questions and Answers
Question 1: In a sequence 2, 5, 10, 17, 26, ___, what is the next number?
- 37 (Correct answer)
- 35
- 38
- 36
Correct answer: 37
The differences are 3, 5, 7, 9, 11 (increasing odd numbers), so 26 + 11 = 37.
Question 2: All A are B. Some B are C. Which conclusion is definitely true?
- Some A may be C (Correct answer)
- All C are A
- No A are C
- All A are C
Correct answer: Some A may be C
Since all A are B and some B are C, it is possible (but not certain) that some A are also C.
Question 3: Which shape logically completes a pattern where the number of sides increases by one in each figure starting from a triangle?
- Pentagon (5 sides)
- Square (4 sides) (Correct answer)
- Hexagon (6 sides)
- Triangle (3 sides)
Correct answer: Square (4 sides)
Starting from a triangle (3 sides), the next shape with one more side is a square (4 sides).
Question 4: If P implies Q and Q implies R, what can be concluded about P and R?
- P implies R (Correct answer)
- R implies P
- P and R are unrelated
- R implies Q only
Correct answer: P implies R
By transitivity, if P → Q and Q → R, then P → R.
Question 5: A series reads: A, C, F, J, O, ___. What letter comes next?
- U (Correct answer)
- T
- V
- S
Correct answer: U
The gaps are +2, +3, +4, +5, +6, placing the next letter 6 positions after O (15th), which is U (21st).
Question 6: Five students stand in a row. Amy is to the left of Bob. Bob is to the left of Carol. Who cannot be standing at the far right?
- Amy
- Carol
- Bob
- Both Amy and Bob (Correct answer)
Correct answer: Both Amy and Bob
Amy is left of Bob, and Bob is left of Carol, so neither Amy nor Bob can occupy the far right position.
