RRB NTPC GK Questions 2026

Static General Knowledge makes up the rest of the General Awareness section in RRB NTPC, and the notices name its topics: General Science and Life Science up to Class 10, History of India and the freedom struggle, Physical, Social and Economic Geography of India and the world, Indian Polity and Governance, Indian Economy, Art and Culture, Indian Literature, Monuments and Places, Flora and Fauna, Famous Personalities, the UN and other world organisations, environmental issues, Transport Systems in India, Important Government and Public Sector Organisations, Common Abbreviations, and Basics of Computers and Computer Applications. RRB frames these as short factual questions: the unit of a physical quantity, the year of a battle, the article of the Constitution, the river a city stands on, the full form of an abbreviation, the headquarters of an organisation. GK24's GK notes on this page cover each topic in English and Hindi, arranged the way the syllabus lists them, with the facts RRB tends to ask placed first. Work through one topic at a time, note the lists (national parks, dances, articles, schedules, awards), and pair each topic with its quiz on GK24 to check what has stayed with you.

Q4022.General ScienceAsked in: NDA · NDA-I 2021, GATMedium

Which one of the following statements about the cleansing action of soap is not true?

  1. A.The oil and dirt gets collected in the centre of the micelle.
  2. B.Soap micelles scatter light.
  3. C.Soaps are ammonium salts of long chain carboxylic acids.
  4. D.Soap forms insoluble precipitates with the calcium and magnesium ions in hard water.
Show answer
Correct answer: C. Soaps are ammonium salts of long chain carboxylic acids.

Soaps are sodium or potassium salts of long-chain carboxylic (fatty) acids, not ammonium salts. A soap molecule has a long hydrocarbon tail that mixes with oil and an ionic head that faces water.

Q4023.GeographyAsked in: NDA · NDA-II 2021, GATEasy

Which one of the following is not a feature of agriculture in India?

  1. A.Subsistence agriculture
  2. B.Pressure of population on agriculture
  3. C.Dependence upon Monsoon
  4. D.Predominance of cash crops
Show answer
Correct answer: D. Predominance of cash crops

Indian farming is dominated by food crops, not cash crops. Most of India’s cropped area is under food grains such as rice, wheat, millets and pulses, grown largely to feed the farm family and the country.

Q4026.General ScienceAsked in: NDA · NDA-II 2023, GATMedium

Which of the following statements are correct about the electrical resistance and resistivity of a wire? 1. Both quantities depend on the area of cross-section of the wire 2. Both depend on the temperature 3. Resistance of the wire is directly proportional to the resistivity of the wire 4. Resistivity of the wire is directly proportional to the length of the wire Select the correct answer using the code given below :

  1. A.1 and 2
  2. B.1 and 3
  3. C.2 and 3
  4. D.2 and 4
Show answer
Correct answer: C. 2 and 3

Both quantities change with temperature, and resistance is directly proportional to resistivity, while resistivity does not depend on the wire’s size.

Q4027.General ScienceAsked in: NDA · NDA-I 2024, GATHard

Which one of the following statements regarding simple pendulum is correct? Simple pendulum has a time period independent of amplitude :

  1. A.only for small amplitudes because then the net force on its bob is independent of its displacement.
  2. B.for any amplitude because the net force on the bob is always proportional to its displacement.
  3. C.for any amplitude because the net force on the bob is independent of its displacement.
  4. D.only for small amplitudes because then the net force on its bob is proportional to its displacement.
Show answer
Correct answer: D. only for small amplitudes because then the net force on its bob is proportional to its displacement.

The restoring force on the bob is mg sin θ. For small angles sin θ is almost equal to θ, so the force becomes proportional to the displacement and points back towards the mean position.

Q4028.General ScienceAsked in: NDA · NDA-II 2024, GATEasy

Which one among the following is correct for a person suffering from myopia?

  1. A.The person can see near objects clearly
  2. B.The person can see distant objects clearly
  3. C.The person cannot distinguish colours
  4. D.The person can neither see near objects nor distant objects clearly
Show answer
Correct answer: A. The person can see near objects clearly

Myopia is short-sightedness: near objects look sharp but distant ones look blurred. In a myopic eye the eyeball is too long or the eye lens is too curved, so light from a distant object comes to a focus in front of the retina instead of on it.

Q4030.Indian EconomyAsked in: NDA · NDA-II 2025, GATMedium

With which of the following was the Bretton Woods System NOT associated?

  1. A.International Monetary Fund
  2. B.Economic recovery after the Second World War
  3. C.International Bank for Reconstruction and Development
  4. D.Establishment of a monetary system based on floating exchange rate
Show answer
Correct answer: D. Establishment of a monetary system based on floating exchange rate

Bretton Woods set up fixed, not floating, exchange rates. At the Bretton Woods Conference in New Hampshire, USA, in July 1944, 44 Allied nations agreed on a new post-war money order.

Q4031.General ScienceAsked in: NDA · NDA-II 2026, GATMedium

Consider the following pairs : Chemical Reaction — Type of Chemical Reaction I. Fe(s) + CuSO₄(aq.) → FeSO₄(aq.) + Cu(s) — Displacement reaction II. Na₂SO₄(aq.) + BaCl₂(aq.) → BaSO₄(s) + 2NaCl(aq.) — Double displacement reaction III. Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g) — Redox reaction IV. 2KClO₃(s) → 2KCl(s) + 3O₂(g) — Thermal decomposition reaction How many of the pairs given above are correctly matched?

  1. A.One
  2. B.Two
  3. C.Three
  4. D.All four
Show answer
Correct answer: D. All four

Each reaction is labelled with its correct type, so every pair is matched correctly. In I, iron is more reactive than copper and pushes it out of copper sulphate, a displacement reaction.

Q4032.EnvironmentMedium

Over which period is the Green Diwali Campaign being run?

  1. A.1 October to 31 October 2026
  2. B.20 October to 8 November 2026
  3. C.20 October to 20 November 2026
  4. D.8 October to 8 November 2026
Show answer
