SSC CGL GK Questions 2026

Static GK decides the General Awareness score in SSC CGL. Of the 25 questions in Tier-I and the 25 in Tier-II Paper-I, most come from Indian Polity, History, Geography, the Economy and General Science, the areas the CGL 2026 notice lists as History, Culture, Geography, Economic Scene, General Policy and Scientific Research relating to India and its neighbouring countries. Polity questions ask about articles, parts and schedules of the Constitution, amendments, the President, Parliament, the Supreme Court and constitutional bodies. History covers the Indus Valley, the Mauryas and Guptas, the Delhi Sultanate and Mughals, and the freedom struggle from 1857 to 1947. Geography asks about rivers, soils, climate, national parks, minerals and world physical features. The Economy part asks about budget terms, the RBI, banking and basic concepts. General Science is school-level Physics, Chemistry and Biology. This page holds GK24's topic-wise GK notes for SSC CGL, written as short facts and tables so a topic can be revised in one sitting. Read a topic, then solve its previous-year questions and quiz on this site to check what you retained.

Which one of the following statements regarding Cholera is correct?

  1. A.Cholera is a disease that causes loss of memory
  2. B.Cholera is a disease of muscles due to consumption of alcohol
  3. C.Cholera is a disease due to consumption of contaminated food or water
  4. D.Cholera is a genetic disease

It is caused by the bacterium Vibrio cholerae, which spreads through food and water polluted with human faeces. The bacterium was identified by Robert Koch in 1883.

Q1645.Indian HistoryAsked in: NDA · NDA-I 2017, GATMedium

Which one of the following statements regarding King Krishnadevaraya is NOT correct ?

  1. A.He was a great scholar of Telugu and Sanskrit
  2. B.Foreign travellers Paes and Nuniz visited his court
  3. C.Barbosa praised him for the great justice and equity prevailing in his empire
  4. D.He wrote his magnum opus Amuktamalyada in Sanskrit
Show answer
Correct answer: D. He wrote his magnum opus Amuktamalyada in Sanskrit

Amuktamalyada is a Telugu work, not a Sanskrit one, so this statement is wrong. Krishnadevaraya (ruled 1509–1529) was the greatest king of the Tuluva dynasty of Vijayanagara.

Q1646.General ScienceAsked in: NDA · NDA-II 2017, GATMedium

Which one of the following is a chemical change?

  1. A.Cutting of hair
  2. B.Graying of hair naturally
  3. C.Swelling of resin in water
  4. D.Cutting of fruit
Show answer
Correct answer: B. Graying of hair naturally

Hair turns grey because the chemical make-up of the hair changes as the body stops producing the pigment melanin, so new substances form and the change cannot be reversed.

Q1648.General ScienceAsked in: NDA · NDA-I 2017, GATMedium

Which one of the following physical quantities does NOT affect the resistance of a cylindrical resistor ?

  1. A.The current through it
  2. B.Its length
  3. C.The resistivity of the material used in the resistor
  4. D.The area of cross-section of the cylinder
Show answer
Correct answer: A. The current through it

The resistance of a conductor depends on its material and shape, not on how much current flows through it. For a cylindrical conductor, R = ρL/A, where ρ is the resistivity of the material, L the length and A the area of cross-section.

Q1651.General ScienceAsked in: NDA · NDA-I 2019, GATMedium

Which one of the following statements regarding Penicillin is correct ?

  1. A.Penicillin resistant bacteria can store this antibiotic in vacuole
  2. B.Penicillin resistant bacteria can degrade this antibiotic by an enzyme called β-lactamase
  3. C.Penicillin resistant bacteria can degrade this antibiotic by an enzyme called lactic acid dehydrogenase
  4. D.Penicillin is not absorbed by bacteria; so most bacteria are resistant
Show answer
Correct answer: B. Penicillin resistant bacteria can degrade this antibiotic by an enzyme called β-lactamase

The enzyme breaks the β-lactam ring that gives penicillin its power. Penicillin was discovered by Alexander Fleming in 1928 from the mould Penicillium notatum.

Which one of the following statements is correct with regard to the material of electrical insulators ?

  1. A.They contain no electrons
  2. B.Electrons do not flow easily through them
  3. C.They are crystals
  4. D.They have more number of electrons than the protons on their surface
Show answer
Correct answer: B. Electrons do not flow easily through them

In an insulator the electrons are tightly bound to their atoms, so there are almost no free electrons to carry a current.

Q1653.General ScienceAsked in: NDA · NDA-II 2017, GATMedium

Zinc is used to protect iron from corrosion because zinc is

  1. A.more electropositive than iron
  2. B.cheaper than iron
  3. C.a bluish white metal
  4. D.a good conductor of heat and electricity
Show answer
Correct answer: A. more electropositive than iron

Zinc gives up electrons more readily than iron, so it corrodes first and keeps the iron safe. Coating iron or steel with a thin layer of zinc is called galvanisation.

Which one of the following statements regarding Electrocardiogram is correct ?

  1. A.Electrocardiogram is graphical representation of electrical activity of cornea
  2. B.Electrocardiogram is graphical representation of activity of kidney
  3. C.Electrocardiogram is graphical representation of activity of brain
  4. D.Electrocardiogram is graphical representation of electrical activity of heart
Show answer
Correct answer: D. Electrocardiogram is graphical representation of electrical activity of heart

An ECG records the electrical signals that make the heart muscle contract with each beat. Each heartbeat starts at the sino-atrial (SA) node, the natural pacemaker in the right atrium.

Q1655.General ScienceAsked in: NDA · NDA-I 2025, GATEasy

We hear an echo due to

  1. A.Refraction of sound waves
  2. B.Reflection of sound waves
  3. C.Diffraction of sound waves
  4. D.Resonance due to sound waves
Show answer
Correct answer: B. Reflection of sound waves

An echo is sound that bounces back from a hard surface such as a wall, cliff or hill and reaches our ears again.

Q1657.General ScienceAsked in: NDA · NDA-II 2017, GATEasy

Step-up transformers are used for

  1. A.increasing electrical power
  2. B.decreasing electrical power
  3. C.decreasing voltage
  4. D.increasing voltage
Show answer
Correct answer: D. increasing voltage

A step-up transformer raises an alternating voltage, using more turns in its secondary coil than in its primary. A transformer works on electromagnetic induction and only with alternating current.

Q1659.General ScienceAsked in: NDA · NDA-I 2020, GATMedium

In case of a concave mirror, if an object is kept between principal focus F and pole P of the mirror, then which one of the following statements about the image is NOT correct?

  1. A.The image will be virtual
  2. B.The image will be enlarged or magnified
  3. C.The image will be formed at infinity
  4. D.The image will be erect
Show answer
Correct answer: C. The image will be formed at infinity

For an object between F and P, the image forms behind the mirror, not at infinity. When an object is placed between the pole and the principal focus of a concave mirror, the reflected rays spread out and never meet in front of the mirror.
