Question 1 Reasoning
Select the word-pair that best represents a similar relationship to the one expressed in the pair of words given below.\n\nPressure: Pascal
- A. Work: Joule
- B. Momentum: Newton
- C. Force: Watt
- D. Electric Current: Kelvin
Correct answer: A. Work: Joule
Correct answer (Option A):\nPascal is the SI unit of Pressure. Similarly, Joule is the standard SI unit of Work. Therefore, the same physical quantity-to-unit relationship is maintained.\n\nWhy others are wrong:\nOption B is incorrect because the SI unit of momentum is kg·m/s, whereas Newton is the unit of Force. Option C is incorrect because the SI unit of force is Newton, while Watt is the unit of Power. Option D is incorrect because the SI unit of Electric Current is Ampere, whereas Kelvin is the unit of Temperature.\n\nStudy tip:\nUnit-quantity pairs are common in analogy tests. Keep a list of standard SI units for mechanical and electrical parameters handy.
Question 2 Reasoning
Select the correct option that indicates the arrangement of the following words in a logical and meaningful order (in terms of food chain).\n1. Grass\n2. Grasshopper\n3. Frog\n4. Snake\n5. Eagle
- A. 1, 2, 3, 4, 5
- B. 2, 3, 4, 5, 1
- C. 3, 4, 5, 2, 1
- D. 2, 4, 3, 1, 5
Correct answer: A. 1, 2, 3, 4, 5
Correct answer (Option A):\nThe logical food chain sequence progresses from primary producer to top predator: Grass (1) is eaten by a Grasshopper (2), which is consumed by a Frog (3), which is eaten by a Snake (4), and finally the Snake is preyed upon by an Eagle (5). Hence, the exact order is 1, 2, 3, 4, 5.\n\nWhy others are wrong:\nOptions B, C, and D do not arrange the steps in a functional ecological sequence, placing consumers before producers or disrupting predator-prey linkages.\n\nStudy tip:\nFood chain hierarchies always trace linear energy transfers from primary producers upward to apex predators.
Question 3 Reasoning
CEG is related to KMO in a certain way based on the English alphabetical order. In the same way, GIK is related to OQS. To which of the following is MOQ related, following the same logic?
- A. LNP
- B. BDF
- C. UWY
- D. IKM
Correct answer: C. UWY
Correct answer (Option C):\nLet us trace the position adjustments between corresponding letters of CEG and KMO:\nC (+8) → K\nE (+8) → M\nG (+8) → O\nThe pattern involves shifting each letter forward by 8 positions. Applying this to MOQ:\nM (+8) → U\nO (+8) → W\nQ (+8) → Y\nTherefore, MOQ is related to UWY.\n\nWhy others are wrong:\nOptions A, B, and D fail to apply a steady +8 positional shifts systematically to all three tracking positions.\n\nStudy tip:\nQuickly verify positional shifts by referencing their index values (A=1, Z=26) to systematically diagnose alphabetical rules.
Question 4 Reasoning
In a certain code language, 'he is right' is coded as 'ab yo km' and 'right now here' is coded as 'km gh bd'. How is 'right' coded in the given language?
- A. gh
- B. yo
- C. ab
- D. km
Correct answer: D. km
Correct answer (Option D):\nComparing the phrase 'he is right' (coded as 'ab yo km') with 'right now here' (coded as 'km gh bd'), we identify that the only common word in both statements is 'right'. Looking at the coded sequences, the only common token present across both sets is 'km'. Thus, 'right' maps directly to 'km'.\n\nWhy others are wrong:\nOption A (gh) belongs exclusively to the second code statement. Options B and C (yo, ab) belong exclusively to components of the first phrase.\n\nStudy tip:\nFictional code language matching is solved quickly through the method of standard set intersection and eliminating unique items.
Question 5 Reasoning
A dice has its faces marked by letters R, S, T, U, V and W. Two positions of the same dice are shown. The first view presents faces T, V, S. The second view presents faces U, W, S. Which face is opposite to face R?
- A. V
- B. T
- C. W
- D. S
Correct answer: D. S
Correct answer (Option D):\nFrom the two configurations, face S is adjacent to T, V, U, and W. Since a single face can have at most four adjacent faces, the remaining unmentioned letter R must be the face that is strictly opposite to S. Consequently, the face opposite to R is S.\n\nWhy others are wrong:\nOptions A, B, and C name faces V, T, and W respectively, all of which are clearly observed to be adjacent to S and separate from R.\n\nStudy tip:\nWhen one face appears in multiple orientations alongside four distinct faces, it is always directly opposite the sixth remaining face.
