RRB Group D GK Questions 2026

Static GK is not a separate section in RRB Group D, but it decides most of the paper's recall marks. General Science is 25 questions of Physics, Chemistry and Life Sciences at 10th standard (CBSE) level as per CEN 09/2025, and the 20 General Awareness questions lean on the standing facts behind the news: the sport, the award, the institution, the state, the river or the scientist an event touches. This page holds GK24's topic-wise GK notes for RRB Group D. The General Science notes go topic by topic through motion and force, work, energy and power, gravitation, heat, light, sound, electricity and magnetism, atomic structure and the periodic table, chemical reactions, acids, bases and salts, metals and non-metals, and carbon compounds, and the Life Sciences notes cover cells, the human body, nutrition, diseases, plants and genetics. The static GK notes cover Indian Railways zones and facts, national symbols, first and largest in India and the world, awards and honours, important days, books and authors, sports GK, art and culture, and the basics of Indian Polity, Geography, History and the Economy. Each note is short facts and tables that can be revised in one sitting. Read a note, then solve its quiz and the previous-year questions on this site to check what stayed.

  2. B.Embryo → egg → zygote → seed
  3. C.Egg → embryo → zygote → seed
  4. D.Egg → seed → zygote → embryo

Starting from rest a vehicle accelerates at the rate of 2 m/s² towards east for 10 s. It then stops suddenly. It then accelerates again at a rate of 4√2 m/s² for next 10 s towards south and then again comes to rest. The net displacement of the vehicle from the starting point is

  1. A.100 m
  2. B.200 m
  3. C.300 m
  4. D.400 m
Show answer
Correct answer: C. 300 m

The vehicle goes 100 m east and 200√2 m south, and the straight-line distance between start and finish is √(100² + (200√2)²) = 300 m. Each leg starts from rest, so the distance covered is s = ½at².

Q664.General ScienceAsked in: NDA · NDA-I 2018, GATEasy

The Poisonous nature of Carbon monoxide (CO) is due to its

  1. A.insolubility in water
  2. B.ability to form a complex with haemoglobin
  3. C.ability to reduce some metal oxides
  4. D.property of having one sigma bond
Show answer
Correct answer: B. ability to form a complex with haemoglobin

Carbon monoxide binds to the haemoglobin of red blood cells to form carboxyhaemoglobin, so the blood can no longer carry oxygen to the tissues.

Q675.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IEasy

Which combination of three resistors R1, R2 and R3 has minimum total resistance? (Consider R1 = 1 Ω, R2 = 2 Ω and R3 = 3 Ω)

  1. A.When all are connected in parallel
  2. B.When all are connected in series
  3. C.When R1 and R2 are connected in parallel and R3 is in series of them
  4. D.When R1 and R3 are connected in parallel and R2 is in series of them
Show answer
Correct answer: A. When all are connected in parallel

In parallel the equivalent resistance is always smaller than the smallest single resistor, so here it falls below 1 Ω. For resistors in parallel, 1/R = 1/R1 + 1/R2 + 1/R3 = 1/1 + 1/2 + 1/3 = 11/6, so R = 6/11 Ω, about 0.55 Ω. Each extra parallel…

Para athletics places competitors in classes so that athletes with a comparable degree of impairment face one another, and an event is then named by the distance along with the class, which is why Dilip Gavit's gold is recorded as the Men's 100m T47 and not merely as the 100…
