CDS Previous Year GK Questions

Previous-year questions are the most reliable guide to the CDS General Knowledge paper, because the syllabus in the notice is one paragraph long and the paper is not. UPSC uploads the question papers of every CDS on upsc.gov.in the day after the exam, so a full record of what was asked exists for each cycle. Reading them shows the weight of each area, the depth UPSC expects in Polity, History, Geography, Economy and Science, and the question forms it prefers: statements with "which of the above are correct", "how many of the following pairs are correctly matched", match the lists, and arrange in chronological order. Many topics return: writs and constitutional bodies, dynasties and reform movements, Ramsar sites and World Heritage sites, budget and balance-of-payments terms, and school science applied to everyday situations. This page collects CDS previous-year General Knowledge questions in English and Hindi, each with the correct answer, an explanation and the topic it belongs to, so that a question leads you to the GK note that covers it. Use them in three passes: untimed to learn, timed to build speed, and a week later to revisit your wrong answers.

Which one of the following statements with regard to the ultraviolet light is not correct?

  1. A.It is an electromagnetic wave.
  2. B.It can travel through vacuum.
  3. C.It is a longitudinal wave.

Q475.General ScienceAsked in: CDS · CDS-I 2021, GKMedium

We are given three copper wires of different lengths and different areas of cross-section. Which one of the following would have highest resistivity?

  1. A.Copper wire of 50 cm length and 1 mm diameter
  2. B.Copper wire of 25 cm length and 0.5 mm diameter
  3. C.Copper wire of 10 cm length and 2.0 mm diameter
  4. D.All the wires would have same resistivity
Show answer
Correct answer: D. All the wires would have same resistivity

Resistivity is a property of the material and its temperature, not of the wire's shape, so every copper wire has the same resistivity.

Q477.Indian EconomyAsked in: CDS · CDS-II 2022, GKEasy

Which one of the following central features is not associated with Capitalist Economy?

  1. A.There is generalised commodity production - it has market value.
