Bihar Previous Year GK Questions

Previous-year questions show what BPSC and BSSC actually ask, which the broad syllabus in an advertisement cannot. Reading the papers of recent cycles shows the weight of each area, the level of detail expected in Polity, History, Geography, the Economy and Science, how current affairs are framed, and how often Bihar-specific facts appear. Many questions return in substance with the options changed: the same constitutional articles, freedom movement events, rivers, schemes and awards. BPSC publishes question booklets of its exams on its website, and the answer keys are released after each exam. This page collects previous-year questions for Bihar exams as GK24 adds them, in English and Hindi, each with the correct answer, a short explanation and the topic it belongs to, so a question leads you to the GK note that covers it. Use them in three passes: solve a set untimed to learn, solve a set timed to build speed, and return to your wrong answers a week later. Remember the marking while practising: one-third of a mark is lost for a wrong or unmarked answer in the CCE Prelims, and 1 mark for a wrong answer in BSSC. Pair PYQs with the quizzes and daily current affairs on this site.

  4. D.Rolling friction > Kinetic friction > Static friction
Show answer
Correct answer: B. Static friction > Kinetic friction > Rolling friction

For the same pair of surfaces the order of friction is always static, then kinetic, then rolling. Static friction is the largest because the surfaces interlock while at rest and that grip has to be broken to start motion.

Q38.General ScienceAsked in: Bihar · 13th September 2025Medium

The potential energy of a freely falling body continuously decreases.

  1. A.The principle of conservation of energy is not violated
  2. B.The principle of conservation of energy is violated
  3. C.Gravitational force is violated
  4. D.Gravitational force is not violated
Show answer
Correct answer: A. The principle of conservation of energy is not violated

As the body falls its height shrinks, so the potential energy m g h falls, but exactly that much energy reappears as kinetic energy, half m v squared, because the body speeds up.
