NTA Logical Reasoning 1 — Questions and Answers
Question 1: If all Bloops are Razzles and all Razzles are Lazzles, then all Bloops are definitely:
- Lazzles (Correct answer)
- Razzles only
- Neither Lazzles nor Razzles
- Cannot be determined
Correct answer: Lazzles
By the transitive property of syllogism, if Bloops⊆Razzles and Razzles⊆Lazzles, then Bloops⊆Lazzles.
Question 2: What comes next in the sequence: 2, 6, 12, 20, 30, ?
- 42 (Correct answer)
- 36
- 40
- 44
Correct answer: 42
The differences are 4, 6, 8, 10, 12, so the next term is 30 + 12 = 42.
Question 3: A is taller than B; B is taller than C; D is shorter than A but taller than B. Who is the tallest?
- A (Correct answer)
- B
- C
- D
Correct answer: A
Since A > D > B > C in height, A is the tallest.
Question 4: If FIRE = 6935 and WIND = 2974, what is FIND?
- 6974
- 2935
- 9724 (Correct answer)
- 6397
Correct answer: 9724
F=6, I=9, R=3, E=5; W=2, I=9, N=7, D=4; so FIND = F(6), I(9), N(7), D(4) = 6974.
Question 5: Pointing to a woman, a man says, 'She is the daughter of the only child of my grandfather.' How is the woman related to the man?
- Sister (Correct answer)
- Cousin
- Mother
- Daughter
Correct answer: Sister
The only child of his grandfather is his father/mother; the daughter of that person is his sister.
Question 6: Which number is the odd one out: 4, 9, 16, 25, 35, 49?
- 35 (Correct answer)
- 4
- 25
- 49
Correct answer: 35
All other numbers are perfect squares (2², 3², 4², 5², 7²), but 35 is not a perfect square.
