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

Q11462.Science & TechnologyMedium

Quantum key distribution is considered secure mainly because of which principle?

  1. A.Keys are encrypted twice before transmission
  2. B.An unknown quantum state cannot be copied and measuring it disturbs it
  3. C.Photons travel faster than electrical signals
  4. D.Quantum channels use frequencies that cannot be received
Show answer
Correct answer: B. An unknown quantum state cannot be copied and measuring it disturbs it

The no cloning theorem forbids an exact copy of an unknown state, and any measurement changes the state, so an eavesdropper on the channel inevitably leaves statistical traces that the two legitimate parties detect when they compare a sample of their key.

Q11463.Science & TechnologyMedium

Shor’s algorithm is significant for quantum computing because it can efficiently perform which task?

  1. A.Searching an unsorted database
  2. B.Factoring large integers
  3. C.Sorting a list of numbers
  4. D.Compressing image data
Show answer
Correct answer: B. Factoring large integers

Peter Shor published the algorithm in 1994, and it would let a sufficiently large quantum computer break the large number factorisation on which public key encryption such as the RSA system depends.
