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

Q3361.General ScienceAsked in: NDA · NDA-I 2024, GATEasy

Water gas is a mixture of :

  1. A.CO₂ and H₂
  2. B.CO and H₂
  3. C.CO₂ and H₂O
  4. D.CO and H₂O
Show answer
Correct answer: B. CO and H₂

Water gas is made by passing steam over red-hot coke, and the reaction C + H₂O → CO + H₂ gives carbon monoxide and hydrogen in roughly equal volumes.

Q3362.General ScienceAsked in: NDA · NDA-II 2026, GATMedium

In humans, the exit of partially digested food from the stomach into the small intestine is regulated by which one of the following structures/processes?

  1. A.Peristalsis
  2. B.Muscular walls of stomach
  3. C.Sphincter muscle
  4. D.Villi in small intestine
Show answer
Correct answer: C. Sphincter muscle

A ring of muscle at the lower end of the stomach, the pyloric sphincter, opens and closes to let food pass into the small intestine a little at a time.

Q3363.Government SchemesHard

Why was PM-DAKSH subsumed under PMKVY from 2024-25?

  3. C.The three implementing corporations were wound up
  4. D.Its target groups were transferred to state governments
Show answer
Correct answer: B. Its job roles, drawn from the Skill India Digital Hub, duplicated those of PMKVY

PM-DAKSH was an additionality to PMKVY, and every job role used for skill training under it was taken from the Skill India Digital Hub portal, where PMKVY job roles are also listed.

Q3366.Government SchemesEasy

PM-DAKSH, now subsumed under PMKVY, was a scheme of which ministry?

  1. A.Ministry of Skill Development and Entrepreneurship
  2. B.Ministry of Social Justice and Empowerment
  3. C.Ministry of Rural Development
  4. D.Ministry of Labour and Employment
Show answer
Correct answer: B. Ministry of Social Justice and Empowerment

PM-DAKSH was a Central Sector Scheme of that ministry, and its Department of Social Justice and Empowerment ran it through three corporations, NSFDC, NBCFDC and NSKFDC, which reimbursed training costs to the institutes.

Q3367.Summits & ConferencesMedium

Which policy document is being released at the Fisheries Investors and Exporters Conclave 2026?

  1. A.Madhya Pradesh Fisheries Investment and Export Guidelines
  2. B.National Inland Fisheries Policy
  3. C.Blue Revolution Charter
  4. D.Reservoir Cage Culture Code
Show answer
Correct answer: A. Madhya Pradesh Fisheries Investment and Export Guidelines

This is a state policy, and its purpose is to ease investment across the parts of the fisheries value chain: hatcheries, fish seed and feed, reservoir and cage fisheries, aquatic animal health, processing, cold-chain infrastructure, logistics, value addition and market development.

Q3371.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IMedium

Which of the following statements regarding Carnot engine is/are correct?

1. It is an irreversible engine operating between two temperatures T1 (source) and T2 (sink).

2. Its efficiency is given by η = 1 − T2/T1, where T1 is the temperature of source and T2 is the temperature of sink.

Select the answer using the code given below.

  1. A.1 only
  2. B.2 only
  3. C.Both 1 and 2
  4. D.Neither 1 nor 2
Show answer
Correct answer: B. 2 only

A Carnot engine is an ideal reversible engine, not an irreversible one, and its efficiency is 1 − T2/T1 with temperatures in kelvin.

Q3373.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IMedium

Which one among the following statements is correct?

  1. A.The total mechanical energy of a system is conserved if the forces, doing work on it, are conservative.
  2. B.The total mechanical energy of a system is conserved if the forces, doing work on it, are non-conservative.
  3. C.The total mechanical energy of a system remains constant.
  4. D.Every force encountered in mechanics does have an associated well-defined potential energy.
Show answer
Correct answer: A. The total mechanical energy of a system is conserved if the forces, doing work on it, are conservative.

When only conservative forces do work on a system, the sum of its kinetic and potential energy stays the same; this is the principle of conservation of mechanical energy.

Q3374.GeographyAsked in: UPSC CAPF · CAPF 2025, Paper IEasy

The seasonal variations in the amount of solar energy that any place on the Earth receives are influenced by

  1. A.the speed of rotation of the Earth
  2. B.pollution
  3. C.cloudiness
  4. D.the inclination of the Earth about its axis
Show answer
Correct answer: D. the inclination of the Earth about its axis

Because the axis is tilted and keeps pointing the same way as the Earth goes round the Sun, each place gets more sunlight in one half of the year and less in the other.

Q3375.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IMedium

For a particle in uniform circular motion (radius R and angular velocity ω), the magnitude and direction of acceleration, respectively are

  1. A.ωR, along the radius outward
  2. B.ωR, towards the centre of the circle
  3. C.ω²R, towards the centre of the circle
  4. D.ω²R, along the linear velocity
Show answer
Correct answer: C. ω²R, towards the centre of the circle

In uniform circular motion the speed stays the same but the direction keeps turning, and that change needs an acceleration pointing to the centre.

Q3376.Computer AwarenessAsked in: UPSC CAPF · CAPF 2025, Paper IEasy

1 gigabyte in binary system is equivalent to

  1. A.1000 kilobytes
  2. B.1024 megabytes
  3. C.1200 megabytes
  4. D.10000 kilobytes
Show answer
Correct answer: B. 1024 megabytes

In the binary system every step up the ladder of memory units is a factor of 2 raised to 10, that is 1024, so one gigabyte holds 1024 megabytes.

Q3377.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IEasy

A uniform current-carrying narrow solenoid produces

  1. A.uniform magnetic field inside the solenoid
  2. B.uniform magnetic field outside the solenoid
  3. C.magnetic field with straight field lines in all the regions
  4. D.magnetic field with oscillating nature
Show answer
Correct answer: A. uniform magnetic field inside the solenoid

Inside a long, narrow solenoid the field lines run straight and parallel and are evenly spaced, which is the picture of a uniform field.
