The National Crime Records Bureau compiles crime statistics from across the country and maintains records such as fingerprints through its systems. It supports police work with data rather than performing judicial or appointing functions.

Question 12General Knowledge and Current Affairs

An operator receives an email claiming to be from a bank and asking for an OTP to 'verify' an account. What is the most appropriate action?

  1. Forward the OTP to colleagues to check if it works
  2. Enter the OTP on the link provided in the email
  3. Reply with the OTP after confirming the sender's name
  4. Ignore and report the email without sharing the OTP Correct answer.

Explanation

A one-time password should never be shared, because no genuine bank asks for it by email or phone. The safest response is to ignore the message and report it as a phishing attempt.

Question 13General Knowledge and Current Affairs

In Uttar Pradesh, which officer heads the police administration at the district level?

  1. The Chief Development Officer
  2. The District Education Officer
  3. The District Judge
  4. The Superintendent of Police or Senior Superintendent of Police Correct answer.

Question 17General Knowledge and Current Affairs

Which Indian institution is responsible for conducting the decennial census of population?

  1. The Reserve Bank of India
  2. The Office of the Registrar General and Census Commissioner Correct answer.
  3. The National Sample Survey Office
  4. The Election Commission of India

Explanation

The census is conducted by the Office of the Registrar General and Census Commissioner of India under the Ministry of Home Affairs. It is a national statistical exercise carried out every ten years.

Question 18General Knowledge and Current Affairs

A police operator must send an urgent official message to several district offices. Which method is most appropriate for ensuring delivery and accountability?

  1. Sending it through the official government communication channel with a record kept Correct answer.
  2. Writing it on a notice board at the police station
  3. Telling a colleague to pass on the message verbally
  4. Posting the message on a public social media page

Explanation

Official communication should travel through authorised government channels, such as official email or a secure messaging system, so that a record is maintained. This supports accountability and confidentiality.

Question 19General Knowledge and Current Affairs

Which statement correctly describes the relationship between the Fundamental Rights and the Directive Principles of State Policy in the Indian Constitution?

  1. Fundamental Rights apply only to government employees
  2. Directive Principles override Fundamental Rights in every case
  3. Fundamental Rights are justiciable, while Directive Principles are guidelines for governance Correct answer.
  4. Both are enforceable in courts in exactly the same manner

Explanation

Fundamental Rights in Part III are enforceable through courts, whereas Directive Principles in Part IV are non-justiciable guidelines for making policy. Courts have held that the two must be read harmoniously.

Question 20General Knowledge and Current Affairs

The Uttar Pradesh Police has a specialised wing for investigating economic offences and serious fraud. Which of the following best matches this description?

  1. The Criminal Investigation Department, which handles specialised investigations Correct answer.
  2. The Fire Services, which responds to fires
  3. The Home Guards, which assist during emergencies
  4. The Traffic Police, which manages road movement

Explanation

The Criminal Investigation Department (CID) is a specialised wing that investigates complex and serious crimes, including economic offences, in support of district police. Traffic, fire and Home Guards units perform distinct operational roles.

Question 21General Knowledge and Current Affairs

Which of the following best explains why an operator should use a strong, unique password for each official account?

  1. It makes the computer run faster
  2. It increases the storage capacity of the computer
  3. It removes the need for any backup
  4. It prevents a breach on one account from giving access to other accounts Correct answer.

Explanation

Reusing one password means a single data breach can expose multiple accounts, a risk known as credential stuffing. Unique passwords limit the damage of any one compromise.

Question 22General Knowledge and Current Affairs

Which of the following pairs correctly matches a state with its capital?

  1. Bihar - Ranchi
  2. Uttar Pradesh - Lucknow Correct answer.
  3. Rajasthan - Indore
  4. Madhya Pradesh - Nagpur

Explanation

Lucknow is the capital of Uttar Pradesh. Knowing state capitals is a standard part of general awareness for state-level recruitment examinations.

Question 23General Knowledge and Current Affairs

An operator is asked to prepare a summary of monthly crime figures for a senior officer. Which approach is most sound?

  1. Present only the lowest figures to show improvement
  2. Compile figures from the official registers and verify totals before submission Correct answer.
  3. Estimate the figures from memory to save time
  4. Copy figures from an unrelated district's report

Explanation

Official statistics must be derived from primary records and checked for accuracy before they reach senior officers. Estimation or selective reporting would mislead decision-making.

Question 24General Knowledge and Current Affairs

Which of the following statements about the jurisdiction of the Supreme Court of India is correct?

  1. It functions only as a criminal court
  2. It can hear appeals from High Courts and also has original jurisdiction over certain disputes Correct answer.
  3. It can only hear cases referred by the President
  4. It cannot interpret the Constitution

Explanation

The Supreme Court has appellate jurisdiction over High Court decisions and original jurisdiction in disputes such as those between the Union and states. It is also the final interpreter of the Constitution.

Question 25General Knowledge and Current Affairs

A police station's computer network is affected by ransomware that encrypts files and demands payment. Which immediate step best reflects sound incident response?

  1. Pay the ransom immediately to recover the files
  2. Continue working on the infected machine to finish pending work
  3. Delete all files to hide the incident
  4. Disconnect affected systems from the network and report to the designated cyber authority Correct answer.

Explanation

Isolating infected systems prevents the ransomware from spreading further, and reporting to the designated cyber authority allows proper investigation and recovery. Paying a ransom does not guarantee recovery and encourages further attacks.

Question 26General Knowledge and Current Affairs

In the context of Indian governance, which body is responsible for conducting elections to the Lok Sabha and State Legislative Assemblies?

  1. Election Commission of India Correct answer.
  2. NITI Aayog
  3. Ministry of Home Affairs
  4. Union Public Service Commission

Explanation

The Election Commission of India is a constitutional body established under Article 324, entrusted with the superintendence, direction, and control of elections to Parliament and State Legislatures. It ensures free and fair elections and is independent of the executive. The other bodies perform different functions, such as policy planning, civil service recruitment, and internal security.

Question 27General Knowledge and Current Affairs

Which of the following is the correct sequence of the four Vedas in the order they are traditionally enumerated?

  1. Rigveda, Samaveda, Yajurveda, Atharvaveda Correct answer.
  2. Atharvaveda, Yajurveda, Samaveda, Rigveda
  3. Yajurveda, Atharvaveda, Rigveda, Samaveda
  4. Samaveda, Rigveda, Atharvaveda, Yajurveda

Explanation

The four Vedas are traditionally listed as Rigveda, Samaveda, Yajurveda, and Atharvaveda. The Rigveda is the oldest and most foundational, and the others follow in that order in most traditional enumerations. The alternative sequences jumble this established order.

Question 28General Knowledge and Current Affairs

A police operator is asked to prepare a report on the status of women's representation in the Lok Sabha. Which of the following statements is correct as per the current constitutional provisions?

  1. One-third of seats in the Lok Sabha are reserved for women.
  2. There is no reservation for women in the Lok Sabha. Correct answer.
  3. Half of the seats in the Lok Sabha are reserved for women.
  4. Reservation for women in the Lok Sabha is decided by the Election Commission before each election.

Explanation

The Constitution of India currently does not provide for reservation of seats for women in the Lok Sabha. The 106th Constitutional Amendment Act, 2023, provides for one-third reservation, but it has not yet been implemented and requires a subsequent census and delimitation. Therefore, as of now, there is no reservation for women in the Lok Sabha.

Question 29General Knowledge and Current Affairs

Which of the following best describes the term 'biodiversity hotspot' as used in environmental studies?

  1. An area where a large number of migratory birds congregate during winter.
  2. A protected area where human entry is completely prohibited.
  3. A region with high species richness and a high level of endemism that is under significant threat of habitat loss. Correct answer.
  4. A zone with a high concentration of industrial activity and pollution.

Explanation

A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened by human activities. It must contain at least 1,500 species of vascular plants as endemics and have lost at least 70% of its original habitat. The other options describe different ecological or administrative concepts.

Question 30General Knowledge and Current Affairs

With reference to the Indian economy, which of the following statements about the 'repo rate' is correct?

  1. It is the rate at which the Reserve Bank of India lends short-term funds to commercial banks against government securities. Correct answer.
  2. It is the rate at which the government borrows from the public through treasury bills.
  3. It is the rate at which the Reserve Bank of India absorbs liquidity from the banking system.
  4. It is the rate at which commercial banks lend to their most creditworthy customers.

Explanation

The repo rate is the policy rate at which the Reserve Bank of India provides short-term liquidity to banks against the collateral of government securities. It is a key tool of monetary policy used to control inflation and manage liquidity. The other options describe different rates or operations.

Question 31General Science

In a police wireless room, an operator speaks into a microphone and the sound is converted into an electrical signal. Which property of sound determines its pitch?

  1. Quality
  2. Frequency Correct answer.
  3. Speed
  4. Amplitude

Explanation

Pitch is the sensation produced by the frequency of a sound wave; a higher frequency is heard as a higher pitch. Amplitude controls loudness, while speed depends on the medium and quality depends on the mixture of overtones.

Question 32General Science

A constable's body temperature is measured as 37 degrees Celsius. What is this temperature on the Fahrenheit scale?

  1. 98.6 degrees F Correct answer.
  2. 310 degrees F
  3. 37 degrees F
  4. 66.6 degrees F

Explanation

The conversion is F = (9/5)C + 32, so 37 degrees Celsius gives (9/5 x 37) + 32 = 66.6 + 32 = 98.6 degrees Fahrenheit. This is the familiar normal human body temperature.

Question 33General Science

During evidence handling, an operator notes that a sealed glass bottle of cold drink taken from a refrigerator shows water droplets on its outer surface. What causes these droplets?

  1. Condensation of water vapour in the air on the cold surface Correct answer.
  2. Absorption of light by the bottle
  3. Melting of the glass surface
  4. Leakage of the drink through the glass pores

Explanation

Air contains water vapour, and when it touches a surface colder than its dew point, the vapour loses latent heat and condenses into liquid droplets. Glass is not porous to liquid in this way, so the water comes from the surrounding air, not from inside the bottle.

Question 34General Science

Which part of the human eye controls the amount of light entering it by adjusting the size of the pupil?

  1. Optic nerve
  2. Cornea
  3. Retina
  4. Iris Correct answer.

Explanation

The iris is the coloured muscular ring that changes the pupil's diameter, widening it in dim light and narrowing it in bright light. The retina receives the image, the cornea provides most of the refraction, and the optic nerve carries signals to the brain.

Question 35General Science

Which blood cells are chiefly responsible for transporting oxygen from the lungs to body tissues?

  1. Plasma proteins
  2. White blood cells
  3. Platelets
  4. Red blood cells Correct answer.

Explanation

Red blood cells contain haemoglobin, an iron-containing pigment that binds oxygen in the lungs and releases it in the tissues. White cells defend against infection, platelets help clotting, and plasma proteins perform transport and immune roles but are not the main oxygen carriers.

Question 36General Science

A police jeep travels 120 km in 2 hours. What is its average speed?

  1. 240 km/h
  2. 120 km/h
  3. 60 km/h Correct answer.
  4. 30 km/h

Explanation

Average speed equals total distance divided by total time, so 120 km divided by 2 hours gives 60 km/h. This is the mean speed over the journey, not necessarily the speed at any instant.

Question 37General Science

An operator using a computer notices that a metal chair feels colder to touch than a wooden table in the same room. Which property explains this sensation?

  1. Reflectivity
  2. Thermal conductivity Correct answer.
  3. Specific heat capacity
  4. Latent heat

Explanation

Both objects are at the same room temperature, but metal conducts heat away from the skin much faster than wood, so the skin senses a greater loss of heat and feels cold. Specific heat capacity affects how much heat a body stores, not the rate of heat flow to the hand.

Question 38General Science

Which of the following is a chemical change rather than a physical change?

  1. Dissolving sugar in water
  2. Rusting of an iron bar kept in a damp store room Correct answer.
  3. Cutting a paper sheet into pieces
  4. Melting of ice into water

Explanation

Rusting produces a new substance, hydrated iron oxide, and cannot be reversed simply by physical means, so it is a chemical change. Melting, dissolving and cutting only alter shape or state without forming a new substance.

Question 39General Science

A wireless set is marked with a fuse rating. What is the main function of the fuse in an electrical circuit?

  1. It increases the voltage supplied to the equipment
  2. It converts alternating current into direct current
  3. It melts and breaks the circuit when current exceeds a safe value Correct answer.
  4. It stores charge to supply current during a power cut

Explanation

A fuse contains a thin wire of low melting point that heats up and melts when the current exceeds the rated value, thereby breaking the circuit and protecting equipment and wiring. Charge storage is done by capacitors, rectification by diodes, and voltage change by transformers.

Question 40General Science

Which of the following is the correct unit of electric power?

  1. Ampere
  2. Watt Correct answer.
  3. Coulomb
  4. Ohm

Explanation

Power is the rate of doing work or using energy, and its SI unit is the watt, equal to one joule per second. Coulomb measures charge, ohm measures resistance, and ampere measures current.

Question 41General Science

In a police radio communication system, a signal travels from a transmitter to a distant receiver. Which type of wave carries such radio signals?

  1. Longitudinal sound waves
  2. Transverse water waves
  3. Seismic waves
  4. Electromagnetic waves Correct answer.

Explanation

Radio signals are electromagnetic waves that can travel through vacuum at the speed of light and do not need a material medium. Sound waves need a medium, water waves need a water surface, and seismic waves travel through the earth.

Question 42General Science

Which gas is most abundant in the Earth's atmosphere, and which gas do plants use in photosynthesis?

  1. Oxygen is most abundant; nitrogen is used in photosynthesis
  2. Carbon dioxide is most abundant; oxygen is used in photosynthesis
  3. Nitrogen is most abundant; carbon dioxide is used in photosynthesis Correct answer.
  4. Hydrogen is most abundant; carbon dioxide is used in photosynthesis

Explanation

Dry air is roughly 78 percent nitrogen and 21 percent oxygen, so nitrogen is the most abundant gas. Plants take in carbon dioxide and water to make food during photosynthesis, releasing oxygen.

Question 43General Science

Which of the following is an example of a first-class lever?

  1. A wheelbarrow
  2. A fishing rod
  3. A pair of scissors Correct answer.
  4. A pair of tongs

Explanation

In a first-class lever the fulcrum lies between the effort and the load, as in scissors, where the pivot is between the handles and the blades. A wheelbarrow is second class, while tongs and a fishing rod are third class with the effort between the fulcrum and the load.

Question 44General Science

A police officer standing in the sun wears a white uniform while another wears a black jacket. Which statement correctly explains the difference in heat absorption?

  1. The black jacket absorbs more radiation than the white uniform Correct answer.
  2. Both absorb the same amount because colour does not affect absorption
  3. The white uniform emits more radiation because it is a good absorber
  4. The white uniform absorbs more radiation than the black jacket

Explanation

Dark surfaces are good absorbers and emitters of radiation, while light-coloured surfaces reflect most radiation and absorb less. Hence the black jacket heats up more in sunlight than the white uniform. Colour does affect absorption, so the two are not equal.

Question 45General Science

Which of the following statements about the pH scale is correct?

  1. A solution of pH 3 is acidic and has more hydrogen ions than one of pH 6 Correct answer.
  2. A solution of pH 7 is strongly acidic
  3. A solution of pH 12 is neutral
  4. A solution of pH 3 is basic and has fewer hydrogen ions than one of pH 6

Explanation

Below pH 7 a solution is acidic, and each unit decrease means a tenfold rise in hydrogen ion concentration, so pH 3 is far more acidic than pH 6. pH 7 is neutral, and values above 7 are basic.

Question 46General Science

A substance is found to have a definite volume but no definite shape, and it flows to take the shape of its container. In which state of matter is it?

  1. Solid
  2. Liquid Correct answer.
  3. Gas
  4. Plasma

Explanation

A liquid has a definite volume because its particles are close together, but the particles can slide past one another, so it takes the shape of its container. Solids have definite shape and volume, gases have neither, and plasma is an ionised gas.

Question 47General Science

An operator compares two resistors of 4 ohm and 6 ohm joined in parallel. What is the equivalent resistance of the combination?

  1. 5 ohm
  2. 2.4 ohm Correct answer.
  3. 10 ohm
  4. 24 ohm

Explanation

For two resistors in parallel, the reciprocal of the equivalent resistance equals the sum of the reciprocals, so 1/R = 1/4 + 1/6 = 5/12, giving R = 12/5 = 2.4 ohm. The equivalent resistance in parallel is always less than the smaller resistor.

Question 48General Science

A body starts from rest and moves with a uniform acceleration of 2 m/s squared for 5 seconds. What distance does it cover in this time?

  1. 25 m Correct answer.
  2. 5 m
  3. 10 m
  4. 50 m

Explanation

Using s = ut + (1/2)at squared with u = 0, a = 2 and t = 5, we get s = 0.5 x 2 x 25 = 25 m. The final velocity would be 10 m/s, but the distance is not simply velocity multiplied by time because the speed is changing.

Question 49General Science

A sample of a radioactive element has a half-life of 8 days. What fraction of the original nuclei remains undecayed after 24 days?

  1. One-eighth Correct answer.
  2. One-half
  3. One-fourth
  4. One-sixteenth

Explanation

In 24 days there are 24 divided by 8, that is three half-lives. Each half-life halves the remaining nuclei, so the fraction left is (1/2) cubed, which equals one-eighth.

Question 50General Science

A police vehicle's siren emits a sound of constant frequency. As the vehicle approaches a stationary observer, the observer hears a higher pitch. Which statement best explains this?

  1. The wavelength of the sound increases in front of the moving vehicle
  2. The speed of sound increases because the vehicle is moving
  3. The source emits more sound energy per second as it moves faster
  4. The wavefronts are compressed ahead of the source, so the observed frequency increases Correct answer.

Explanation

This is the Doppler effect: a moving source catches up with its own wavefronts, shortening the wavelength in the direction of motion. Since the wave speed in air stays nearly constant, the shorter wavelength corresponds to a higher observed frequency and higher pitch.
