Railway GK Questions 2026

Static GK in railway exams starts with one shared block: Class 10 science. Every RRB exam on GK24 tests it. Group D has 25 questions on Physics, Chemistry and Life Sciences of 10th CBSE level. JE has 30 in CBT-1 and another 15 on Physics and Chemistry in CBT-2. ALP tests General Science in CBT-1 and Basic Science and Engineering in CBT-2, and NTPC lists general science up to 10th inside General Awareness. Beyond science, the lists differ. NTPC names history and the freedom struggle, geography, polity, the economy, art and culture, environment, computers, abbreviations, transport systems in India, world organisations and government bodies. JE names geography, history and culture, polity, the economy and environmental issues, and adds computers and pollution control in CBT-2. This page holds GK24's topic-wise GK notes for railway exams in English and Hindi: General Science, History, Geography, Polity, Economy, Art and Culture, Environment, Computers and static GK, including Indian Railways. Each note is short facts and tables that can be revised in one sitting. Begin with the science notes, since they serve every railway exam, then add the static topics your exam lists, and test each note with its quiz.

Railway GK Questions with Answers

Q5081.General ScienceAsked in: NDA · NDA-I 2023, GATEasy

Browning of the chopped apple can be minimized by:

  1. A.using table sugar.
  2. B.preserving in a container.
  3. C.using lemon juice.
  4. D.using milk of magnesia.
Show answer
Correct answer: C. using lemon juice.

Lemon juice is acidic and rich in vitamin C, which together slow the enzyme reaction that browns cut apple. When an apple is cut, the enzyme polyphenol oxidase in its cells meets oxygen in the air and oxidises the fruit's phenolic compounds into brown pigments (melanins).

Q5082.General ScienceAsked in: NDA · NDA-I 2025, GATMedium

Which one of the following statements is NOT correct?

  1. A.The molecules of soap are sodium or potassium salts of long chain fatty acids
  2. B.The molecules of soap contain both hydrophobic and hydrophilic ends
  3. C.Detergents are more effective than soaps in hard water
  4. D.In micelles the ionic-end of the molecules is towards oil droplet while the other end faces outside
Show answer
Correct answer: D. In micelles the ionic-end of the molecules is towards oil droplet while the other end faces outside

In a micelle it is the long hydrocarbon tail that points into the oil droplet, while the ionic end faces outward into the water, so statement D reverses the real picture.

Q5084.General ScienceAsked in: NDA · NDA-II 2026, GATHard

An insulating container contains 250 g of water at 20°C. Steam at 100°C is passed through it, heating it up to 25°C. During this process, part of the steam also gets condensed, raising the mass of water to 252 g. If the specific heat of water is 1 Cal g⁻¹ °C⁻¹, then what is the value of the latent heat of steam?

  1. A.530 Cal/g
  2. B.540 Cal/g
  3. C.550 Cal/g
  4. D.560 Cal/g
Show answer
Correct answer: C. 550 Cal/g

The heat given out by 2 g of steam equals the heat taken in by 250 g of water, and that balance gives L = 550 Cal/g. The water warms from 20°C to 25°C, so it absorbs 250 × 1 × 5 = 1250 Cal.

Lactic acid is formed in the muscles during exercise or running. It is formed :

  1. A.to give extra energy from fat.
  2. B.to give extra oxygen from lungs.
  3. C.to give extra energy from glucose.
  4. D.to give extra energy from vitamins.
Show answer
Correct answer: C. to give extra energy from glucose.

When oxygen runs short during hard exercise, muscle cells break glucose down anaerobically, and lactic acid is the by-product. In glycolysis, which takes place in the cytoplasm, one molecule of glucose splits into two molecules of pyruvate and yields a little ATP.
