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.

Previous Year Questions

Q222.Environment & EcologyAsked in: CDS · CDS-II 2026, GKEasy

Which of the following can be considered associated with mitigation of environmental problems ?

  1. A.Biomagnification
  2. B.Accelerated eutrophication
  3. C.Release of Nuclear wastes
  4. D.Categorical disposal of different wastes
Show answer
Correct answer: D. Categorical disposal of different wastes

Sorting wastes into categories and disposing of each in the proper way reduces pollution, so it helps solve environmental problems rather than cause them.

Q226.General ScienceAsked in: CDS · CDS-II 2020, GKMedium

Antibiotic such as penicillin blocks

  1. A.cell wall formation in bacteria
  2. B.RNA synthesis in bacteria
  3. C.DNA synthesis in bacteria
  4. D.division in bacteria
Show answer
Correct answer: A. cell wall formation in bacteria

Penicillin stops bacteria from building their peptidoglycan cell wall, so the weakened cells burst and die. Penicillin binds to and blocks the transpeptidase enzymes, also called penicillin-binding proteins, that cross-link the peptidoglycan chains of the wall.

Q230.Indian EconomyAsked in: CDS · CDS-II 2025, GKHard

Consider the following statements about the Indian Institute of Entrepreneurship (IIE) : 1. The IIE was established in 1999 in Guwahati. 2.

  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

The Indian Institute of Entrepreneurship in Guwahati was set up in 1993, not 1999, while its stated aim is indeed training, research and consultancy for small and micro enterprises.

Q231.General ScienceAsked in: CDS · CDS-II 2026, GKMedium

Which of the following statements is NOT correct ?

  1. A.Hardy-Weinberg Principle says that allele frequencies in a population is unstable
  2. B.Branching descent and natural selection are the two key concepts of Darwinian Theory of evolution
  3. C.Lamarckism is based on inheritance of acquired character
  4. D.The concept of mutation, gene flow, genetic drift, gene recombination and natural selection affect Hardy-Weinberg equilibrium
Show answer
Correct answer: A. Hardy-Weinberg Principle says that allele frequencies in a population is unstable

The Hardy-Weinberg principle states the opposite: allele frequencies in a population stay stable, that is constant, from generation to generation.

Q232.Indian PolityAsked in: CDS · CDS-I 2017, GKMedium

Q233.General ScienceAsked in: CDS · CDS-II 2017, GKEasy

A person throws an object on a horizontal frictionless plane surface. It is noticed that there are two forces acting on this object-(i) gravitational pull and (ii) normal reaction of the surface. According to the third law of motion, the net resultant force is zero. Which one of the following can be said for the motion of the object?

  1. A.The object will move with acceleration.
  2. B.The object will move with deceleration.
  3. C.The object will move with constant speed, but varying direction.
  4. D.The object will move with constant velocity.
Show answer
Correct answer: D. The object will move with constant velocity.

With no net force acting on it, the object keeps moving at the same speed in the same straight line.

Q235.Environment & EcologyAsked in: CDS · CDS-I 2020, GKEasy
