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.

Q3703.General ScienceAsked in: NDA · NDA-II 2026, GATMedium

Which of the following statements is/are correct in respect of Portland cement ? I. Adding more water (higher water-cement ratio) accelerates the initial setting time of cement. II. The addition of a small percentage of gypsum gives the desired retardation. III. Gypsum is added during manufacturing to accelerate the setting time of cement. Select the answer using the code given below :

  1. A.I and II
  2. B.I and III
  3. C.I only
  4. D.II only
Show answer
Correct answer: D. II only

Only statement II is correct: a small amount of gypsum is added to cement to slow down its setting. Portland cement is made by heating limestone and clay to form clinker, which is then ground with about 2 to 3 per cent gypsum (calcium sulphate dihydrate).

Q3704.General ScienceAsked in: NDA · NDA-I 2018, GATMedium

Which one of the following properties is NOT true for graphite ?

  1. A.Hybridisation of each carbon atom is sp³
  2. B.Hybridisation of each carbon atom is sp²
  3. C.Electrons are delocalized over the whole sheet of atoms
  4. D.Each layer is composed of hexagonal rings
Show answer
Correct answer: A. Hybridisation of each carbon atom is sp³

In graphite each carbon atom is sp² hybridised, not sp³, so statement A is the one that is not true.

Q3708.General ScienceAsked in: NDA · NDA-I 2022, GATEasy

Which one of the following reactions is an example of decomposition reaction?

  1. A.CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
  2. B.2AgCl(s) → (sunlight) 2Ag(s) + Cl₂(g)
  3. C.CuO + H₂ → (heat) Cu + H₂O
  4. D.Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s)
Show answer
Correct answer: B. 2AgCl(s) → (sunlight) 2Ag(s) + Cl₂(g)

A single compound, silver chloride, breaks down into two simpler substances, silver and chlorine, which is exactly what a decomposition reaction is.

Q3709.General ScienceAsked in: NDA · NDA-II 2023, GATEasy

What is the action of litmus on ethanol ?

  1. A.Litmus is neutral towards ethanol
  2. B.Ethanol turns blue litmus to red; confirming acidic nature of ethanol
  3. C.Ethanol turns red litmus to blue; confirming basic nature of ethanol
  4. D.Ethanol decolorizes litmus through bleaching action
Show answer
Correct answer: A. Litmus is neutral towards ethanol

Ethanol does not change the colour of either red or blue litmus, because it is neutral. Ethanol, C₂H₅OH, is an alcohol.

Q3712.General ScienceAsked in: NDA · NDA-II 2026, GATEasy

Ionic compounds have high melting and boiling points. This is due to :

  1. A.the presence of strong electrostatic forces between ions in the crystal lattice.
  2. B.the weak intermolecular van der Waals forces.
  3. C.the presence of a 'sea of delocalized electrons'.
  4. D.lower lattice energy.
Show answer
Correct answer: A. the presence of strong electrostatic forces between ions in the crystal lattice.

. Oppositely charged ions in an ionic crystal pull on each other strongly from every side, so a great deal of heat is needed to break the lattice apart.
