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.

SSC CGL GK Questions with Answers

Q7082.GeographyAsked in: NDA · NDA-I 2024, GATMedium

Consider the following statements regarding the International Date Line :

1. It is roughly 180° meridian, which deviates slightly East and West to avoid land areas surrounded by the Atlantic Ocean.

2. The date to the East of this line is (24 hours) earlier than to the West.

Which of the statements given above is/are correct?

  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 date just east of the line is one day behind the date just west of it, but the line runs through the Pacific Ocean, not the Atlantic.

Which one of the following statements about surface tension is correct?

  1. A.It increases when temperature increases
  2. B.It decreases when temperature increases
  3. C.It will remain same with increase or decrease of temperature
  4. D.It will always decrease with increase or decrease of temperature
Show answer
Correct answer: B. It decreases when temperature increases

Heating weakens the attraction between the molecules of a liquid, so its surface pulls less tightly. Surface tension arises because molecules at the surface are pulled inward by their neighbours, making the surface behave like a stretched skin.

Q7085.General ScienceAsked in: NDA · NDA-I 2026, GATEasy

It has been observed that a mirror always forms the image between the pole and the focus, irrespective of the location of the object. Which one of the following is correct in respect of the nature of the mirror?

  1. A.It is a plane mirror.
  2. B.It is a convex mirror.
  3. C.It is a concave mirror of small focal length.
  4. D.It is a concave mirror of large focal length.
Show answer
Correct answer: B. It is a convex mirror.

For any real object, a convex mirror forms a virtual, erect and smaller image behind the mirror, between the pole and the focus.

Q7086.General ScienceAsked in: NDA · NDA-II 2026, GATHard

A heating filament and an ideal resistor of fixed value are connected in series with a DC voltage source. After some time, the filament has reached its operating point so that the current in the circuit is steady. Which one of the following is correct?

  1. A.The steady current is larger than the initial value.
  2. B.The steady voltage across the ideal resistor decreases as compared to its initial value.
  3. C.Overall resistance of the circuit decreases.
  4. D.Power dissipation through the filament increases as compared to its initial value.
Show answer
Correct answer: B. The steady voltage across the ideal resistor decreases as compared to its initial value.

A metal filament's resistance rises as it heats up, so the current falls and the resistor gets a smaller share of the voltage.

Q7091.General ScienceAsked in: NDA · NDA-I 2021, GATEasy

The image we see in plane mirror is

  1. A.real and thus can be photographed.
  2. B.virtual and nearer than the object.
  3. C.virtual and is laterally inverted.
  4. D.real but cannot be photographed.
Show answer
Correct answer: C. virtual and is laterally inverted.

A plane mirror forms an image behind the mirror where light only seems to come from, with left and right swapped.

Q7093.General ScienceAsked in: NDA · NDA-I 2022, GATEasy

What is the current required to light a 60 W incandescent bulb in a domestic supply of 240 V?

  1. A.0.5 A
  2. B.0.25 A
  3. C.1.0 A
  4. D.5.0 A
Show answer
Correct answer: B. 0.25 A

Electric power equals voltage times current, so the current is 60 W ÷ 240 V = 0.25 A. The relation P = VI comes straight from the definitions: voltage is energy per unit charge and current is charge per second, so their product is energy per second, or power.

Q7095.General ScienceAsked in: NDA · NDA-I 2023, GATMedium

Consider the following statements regarding cell wall composition :

1. Bacterial cell wall is made of peptidoglycan.

2. Fungal cell wall is made of cellulose.

3. Animals lack cell wall and have extracellular matrix made up of sugar and proteins.

Select the correct answer using the code given below :

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

Bacteria have peptidoglycan walls and animal cells have no wall, but fungal walls are made of chitin, not cellulose. Statement 1 is correct: peptidoglycan, also called murein, is a mesh of sugars cross-linked by short peptides; penicillin works by blocking its formation.

Q7096.General ScienceAsked in: NDA · NDA-II 2023, GATMedium

In a sexually reproducing organism, which one of the following statements is appropriate both for the parent and offspring?

  1. A.Chromosome number increases but DNA content remains constant
  2. B.Both chromosome number and DNA content remains constant
  3. C.Chromosome number decreases but DNA content remains constant
  4. D.Both chromosome number and DNA content decreases
Show answer
Correct answer: B. Both chromosome number and DNA content remains constant

Meiosis halves them in the gametes, and fertilisation restores them in the offspring. Each parent makes gametes by meiosis, so a human egg or sperm carries 23 chromosomes instead of 46.

Q7098.Indian HistoryAsked in: NDA · NDA-I 2025, GATEasy

Who, among the following, has introduced a resolution in 1882 which is also called the Magna Carta of Local Self-Government in India?

  1. A.Lord Macaulay
  2. B.Lord Canning
  3. C.Lord Ripon
  4. D.Lord William Bentinck
Show answer
Correct answer: C. Lord Ripon

As Viceroy, he issued the Resolution on Local Self-Government of 18 May 1882, remembered as its Magna Carta. Ripon, Viceroy from 1880 to 1884, wanted local boards and municipalities with a majority of elected, non-official members and an elected chairman where possible.

Q7100.General ScienceAsked in: NDA · NDA-II 2026, GATMedium

A hollow prism is filled with water of refractive index 1.34 and white light is incident on the prism. The white light is assumed to have wavelengths ranging from 4020 Å to 6700 Å. What is the corresponding wavelength range in water?

  1. A.3000 Å to 5000 Å
  2. B.4020 Å to 6700 Å
  3. C.5000 Å to 7000 Å
  4. D.5386 Å to 8978 Å
Show answer
Correct answer: A. 3000 Å to 5000 Å

When light enters a denser medium, its wavelength is divided by the refractive index of that medium. The frequency of light is fixed by its source and does not change on refraction.
