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.

RRB NTPC GK Questions with Answers

Q5761.General ScienceAsked in: CDS · CDS-I 2017, GKEasy

Bleeding of gums, falling of teeth, fragile bones and delayed wound healing occur due to the deficiency of which one of the following vitamins?

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

These are the signs of scurvy, the disease caused by a lack of vitamin C (ascorbic acid). Vitamin C is needed to make collagen, the protein that holds together gums, skin, blood vessels and bone.

Q5763.General ScienceAsked in: CDS · CDS-I 2018, GKMedium

Consider the following statements:

1. There is no net moment on a body which is in equilibrium.

2. The momentum of a body is always conserved.

3. The kinetic energy of an object is always conserved.

Which of the statements given above is/are correct?

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

A body in equilibrium has no net force and no net moment on it, while neither momentum nor kinetic energy is conserved in every situation.

Q5766.General ScienceAsked in: CDS · CDS-I 2022, GKEasy

Which one of the following statements is correct about the cell membrane?

  1. A.It is made up of cellulose.
  2. B.It is a permeable structure for all substances.
  3. C.It is flexible and enables the cell to engulf many materials.
  4. D.It does not allow diffusion of gases like oxygen and carbon dioxide.
Show answer
Correct answer: C. It is flexible and enables the cell to engulf many materials.

The cell membrane is flexible, and this lets a cell fold it around food and other material and take it in.

Q5767.General ScienceAsked in: CDS · CDS-II 2022, GKMedium

Which one of the following statements about the process of photosynthesis is correct?

  1. A.Light energy is directly converted to kinetic energy which oxidizes carbon dioxide.
  2. B.Light energy is directly converted to chemical energy which causes reduction of water.
  3. C.Chlorophyll absorbs the chemical energy of light which causes oxidation of carbon dioxide.
  4. D.Chlorophyll absorbs light energy which causes splitting of water molecules and reduction of carbon dioxide.
Show answer
Correct answer: D. Chlorophyll absorbs light energy which causes splitting of water molecules and reduction of carbon dioxide.

Chlorophyll absorbs light energy, which is used to split water and then to reduce carbon dioxide to sugar. In the light reactions, energy trapped by chlorophyll splits water molecules (photolysis), releasing oxygen, hydrogen ions and electrons and producing ATP and NADPH.

Q5768.General ScienceAsked in: CDS · CDS-II 2024, GKEasy

The surface of the concrete structure of a new construction is covered with straw/gunny bags by wetting. This is done to:

  1. A.prevent fast evaporation, until hydration has proceeded well
  2. B.protect the concrete structure from contamination by dust particles
  3. C.prevent development of any fungus on the surface
  4. D.give smoother and cleaner surface over cement structure
Show answer
Correct answer: A. prevent fast evaporation, until hydration has proceeded well

Wet straw or gunny bags keep the fresh concrete moist, so water does not evaporate before the cement has hydrated properly.

Q5770.General ScienceAsked in: CDS · CDS-I 2026, GKMedium

Which one among the following statements regarding the electrical resistivity of a conducting wire is correct?

  1. A.The resistivity of the conductor increases if the length of the wire is increased.
  2. B.The resistivity of the conductor decreases if the length of the wire is increased.
  3. C.The resistivity of the conductor remains the same if the length of the wire is changed.
  4. D.The resistivity of the conductor increases if the cross-sectional area of the wire is increased.
Show answer
Correct answer: C. The resistivity of the conductor remains the same if the length of the wire is changed.

Resistivity is a property of the material itself, so it stays the same when the length of the wire is changed.

Q5772.GeographyAsked in: UPSC Civil Services · CSE Prelims 2019, GS Paper IEasy

On 21st June, the Sun

  1. A.does not set below the horizon at the Arctic Circle
  2. B.does not set below the horizon at Antarctic Circle
  3. C.shines vertically overhead at noon on the Equator
  4. D.shines vertically overhead at the Tropic of Capricorn
Show answer
Correct answer: A. does not set below the horizon at the Arctic Circle

21 June is the summer solstice of the Northern Hemisphere, when the North Pole is tilted towards the Sun and the whole Arctic Circle gets 24 hours of daylight.
