Logical Reasoning
A. 35
B. 49
C. 77
D. 105
Answer: All except 49 are multiples of 7 that are not perfect squares. 49 equals 7 times 7, making it a perfect square.
Logical Reasoning
A. 0 km
B. 15 km
C. 20 km
D. 35 km
Answer: After walking North 15, East 20, South 15, West 20, the person returns to the starting point. Distance is 0 km.
Logical Reasoning
A. 96
B. 128
C. 100
D. 192
Answer: Each term doubles. 64 times 2 equals 128.
Logical Reasoning
A. FSBTFS
B. FSBSFT
C. FTBTFS
D. GSCTGT
Answer: Each letter shifted by plus 1. ERASER becomes FSBTFS.
Logical Reasoning
A. 144
B. 180
C. 192
D. 168
Answer: Each term is doubled: 6×2=12, 12×2=24, 24×2=48, 48×2=96, 96×2=192.
Logical Reasoning
A. 15th
B. 16th
C. 17th
D. 18th
Answer: Reena was 10th from right, meaning 16th from left. After swapping, Meena is at Reena\'s old spot, which is 10th from right. The answer is 18th from right.
Logical Reasoning
A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows
Answer: Some red things are beautiful and all beautiful things are precious, so some red things are precious (II follows). But the chain from roses to valuable has too many partial links (I doesn\'t follow).
Logical Reasoning
A. Definitely true
B. Definitely false
C. Possibly true
D. Cannot be determined
Answer: All statements are \'some\' statements. The chain does not create a definite connection between pens and green.
Logical Reasoning
A. 42
B. 49
C. 56
D. 64
Answer: These are perfect squares: 2², 3², 4², 5², 6². The next is 7² = 49.
Logical Reasoning
A. 120
B. 144
C. 130
D. 146
Answer: The pattern is a times b plus a squared: 2 times 3 plus 4 equals 10. 4 times 5 plus 16 equals 36. 6 times 7 plus 28 equals 70. 8 times 9 plus 64 equals 136. With the given pattern, 8 times 9 equals 146.
Logical Reasoning
A. 10
B. 12
C. 8
D. 14
Answer: The @ operator adds the two numbers: 7+8=15, 3+5=8, 9+2=11, 4+6=10.
Logical Reasoning
A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows
Answer: All cats are animals and all animals are living beings, so some animals are living beings follows. But we cannot conclude some cats are plants.
Logical Reasoning
A. Definitely true
B. Definitely false
C. Possibly true
D. Cannot be determined
Answer: The chain from men to generous passes through multiple partial connections. We cannot definitively conclude that some men are generous.
Logical Reasoning
A. Definitely true
B. Definitely false
C. Possibly true
D. Cannot be determined
Answer: The chain of \'some\' statements creates only partial overlaps at each step. We cannot definitively conclude that some cats are unhealthy.
Logical Reasoning
A. 45
B. 48
C. 51
D. 43
Answer: Using position values with a pattern: S(19)+T(20)+A(1)+R(18)=58, with offset giving 41. For COMET: C(3)+O(15)+M(13)+E(5)+T(20)=56, and with the established coding pattern the answer is 45.
Logical Reasoning
A. 25
B. 36
C. 48
D. 64
Answer: 16=4², 25=5², 36=6², 64=8² are all perfect squares. 48 is not a perfect square, making it the odd one out.
Logical Reasoning
A. QVSQMF
B. QVSQNF
C. QVTQMF
D. QVSQMF
Answer: Each letter is shifted by +1: O to P, R to S, A to B, N to O, G to H, E to F. Applying +1 to PURPLE gives QVSQMF.
Logical Reasoning
A. Definitely true
B. Definitely false
C. Possibly true
D. Cannot be determined
Answer: The conclusion that some birds have eight legs contradicts the established knowledge. Additionally, the chain does not support this conclusion.
Logical Reasoning
A. 360
B. 364
C. 366
D. 358
Answer: Each term is multiplied by 3 and then 1 is added: 1×3+1=4, 4×3+1=13, 13×3+1=40, 40×3+1=121, 121×3+1=364.
Logical Reasoning
A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows
Answer: The partial chain from students to scholars and from learners to teachers cannot be definitively established.
