RRB NTPC Previous Year Paper 01 — Kerala PSC PYQ Practice with Answers

Correct answer (Option A):\nLet us trace the subjects for each person based on the given passage:\n- Rahul: Hindi, Maths, Biology\n- Kusum: Hindi, Maths, Marathi\n- Sameer: Hindi, Biology, History\n- Gita: Marathi, Maths, History, Biology\n- Mihir: History, Biology\n\nLooking at the list, Gita is good in both Marathi and Biology.\nOption A is correct.\n\nWhy others are wrong:\nOption B is incorrect because Kusum is good in Hindi, Maths, and Marathi, but not Biology. Option C is incorrect because Sameer is good in Hindi, Biology, and History, but not Marathi. Option D is incorrect because Mihir is good in History and Biology, but not Marathi.\n\nStudy tip:\nCreating a matrix table with names as rows and subjects as columns helps solve multi-person puzzle questions quickly and accurately.

Correct answer (Option C):\nBased on the analysis of the text:\n- Rahul is good in Hindi, Maths, and Biology.\n- Kusum is good in Hindi and Maths from the first statement, and Marathi and Maths from the third statement. Thus, Kusum is good in Hindi, Marathi, and Maths.\n- Sameer is good in Hindi, Biology, and History.\n- Gita is good in Marathi, Maths, History, and Biology.\n\nTherefore, Kusum is good in only Hindi, Marathi, and Maths.\nOption C is correct.\n\nWhy others are wrong:\nOption A is incorrect because Sameer is good in Hindi, Biology, and History. Option B is incorrect because Rahul is good in Hindi, Maths, and Biology. Option D is incorrect because Gita is good in Marathi, Maths, History, and Biology.\n\nStudy tip:\nPay close attention to the word 'only' in reasoning questions. It means the person must possess exactly those three traits and no other traits.

Correct answer (Option B):\nLet us evaluate the subjects for each person to find the match:\n- Rahul is good in Hindi and Maths. He is also good in Hindi and Biology. Combining these, Rahul is good in Hindi, Maths, and Biology.\n- Kusum is good in Hindi, Maths, and Marathi.\n- Sameer is good in Hindi, Biology, and History.\n- Gita is good in Marathi, Maths, History, and Biology.\n\nThus, Rahul is the one who is good in Maths, Biology, and Hindi.\nOption B is correct.\n\nWhy others are wrong:\nOption A is incorrect because Gita is good in Marathi, Maths, History, and Biology, not Hindi. Option C is incorrect because Sameer is not good in Maths. Option D is incorrect because Mihir is only good in History and Biology.\n\nStudy tip:\nWhen a name appears across multiple clues, aggregate their attributes systematically to avoid confusion during competitive exams.

Correct answer (Option D):\nThe given statement mentions that Hrithik manages to find time to rest despite having a very busy schedule. Let us examine the conclusions:\n- Conclusion I states that Hrithik is an organized person. Being busy and finding time to rest does not conclusively prove or guarantee that someone is generally organized; it could be due to necessity or assistance.\n- Conclusion II states that rest is the most important thing for a busy person. The statement does not mention any hierarchy of importance regarding rest or work for busy individuals.\n\nSince neither conclusion can be logically derived from the statement, neither follows.\nOption D is correct.\n\nWhy others are wrong:\nOption A is incorrect because we cannot definitively assume Hrithik's organizational skills from this single fact. Option B is incorrect because the statement does not claim that rest is the absolute most important requirement. Option C is incorrect because both conclusions are external assumptions.\n\nStudy tip:\nIn statement and conclusion problems, never assume facts outside the scope of the given statement. Avoid general assumptions or absolute terms like 'most important' unless explicitly stated.

Correct answer (Option C):\nTo find the correct order, let us convert each fraction into its decimal value:\nStep 1: 13 / 33 ≈ 0.3939\nStep 2: 20 / 47 ≈ 0.4255\nStep 3: 32 / 47 ≈ 0.6808\nStep 4: 25 / 27 ≈ 0.9259\n\nComparing the decimal values:\n0.3939 < 0.4255 < 0.6808 < 0.9259\n\nThis gives the ascending order:\n13/33 < 20/47 < 32/47 < 25/27\nOption C matches this exact sequence.\nOption C is correct.\n\nWhy others are wrong:\nOption A is incorrect because it places 32/47 before 20/47, which is mathematically false since they have the same denominator and 32 > 20. Option B is incorrect because it incorrectly claims 25/27 < 32/47. Option D is incorrect because it incorrectly states that 20/47 is smaller than 13/33.\n\nStudy tip:\nWhen comparing fractions with the same denominator, such as 20/47 and 32/47, the fraction with the larger numerator is always greater. For others, a quick decimal conversion helps save time.
