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.

Q1809.General ScienceAsked in: NDA · NDA-I 2020, GATMedium

Which one of the following statements about sound is NOT correct?

  1. A.Sound travels at a speed slower than the speed of light
  2. B.Sound waves are transverse waves
  3. C.Sound waves are longitudinal waves
  4. D.Sound travels faster in moist air than in dry air
Show answer
Correct answer: B. Sound waves are transverse waves

This statement is false, because sound in air travels as longitudinal waves, not transverse waves. In a longitudinal wave, the particles of the medium vibrate back and forth along the direction in which the wave moves, forming compressions and rarefactions.

Q1810.General ScienceAsked in: NDA · NDA-II 2021, GATEasy

Power of a lens of focal length 25 cm is

  1. A.+2.5 Dioptre
  2. B.+3 Dioptre
  3. C.+4 Dioptre
  4. D.+5 Dioptre
Show answer
Correct answer: C. +4 Dioptre

Power is the reciprocal of the focal length in metres, so P = 1 ÷ 0.25 m = +4 D. The power of a lens tells how strongly it converges or diverges light.

Q1812.General ScienceAsked in: NDA · NDA-I 2025, GATHard

Two conducting wires of the same material and of equal lengths and equal diameters are first connected in parallel and then in series in a circuit across the same potential difference. The ratio of heat produced in parallel and series combinations is

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

With the same voltage, heat varies inversely as resistance, and the parallel resistance is one-fourth of the series resistance. The two wires are identical, so each has the same resistance R. In series the total resistance is R + R = 2R; in parallel it is R/2.

Q1814.General ScienceAsked in: NDA · NDA-II 2021, GATMedium
