🚂 RRB ALP Technical

These essential MCQ questions are carefully selected from the most important topics in RRB ALP (Railway Recruitment Board — Assistant Loco Pilot) and Technician examinations — conducted by the Railway Recruitment Boards for recruitment into Indian Railways, one of the largest employers in the world. The practice set covers all major sections as per the official RRB ALP syllabus — Mathematics covering number systems, decimals, fractions, percentages, time and work, time and distance and mensuration; Basic Science covering Physics concepts like electricity, magnetism, motion and optics, and Chemistry concepts like elements, compounds and reactions; General Intelligence and Reasoning covering analogies, coding-decoding, syllogisms, series and spatial reasoning; General Awareness covering current affairs, Indian geography, history, polity and science and technology; and Technical Subjects covering trade-specific topics in Electrician, Fitter, Mechanic, Electronics and other relevant ITI trades. Every session on Vooo AI generates fresh, AI-powered MCQs so your RRB ALP and Technician preparation stays thorough, trade-focused and exam-ready. For truly unlimited MCQ practice across all Railways ALP Technical topics, visit Vooo AI Education.

General Intelligence and Reasoning tests the analytical and logical thinking ability that railway operations demand in practical decision-making situations. Analogies, classification, series completion, coding and decoding, blood relations, direction sense, syllogisms, Venn diagrams, spatial reasoning, mirror and water images, and data sufficiency are question types that reward candidates who have developed sharp, flexible, and systematic logical thinking. The reasoning section is particularly valuable because it is one of the few areas of the examination where dedicated practice can produce rapid and significant score improvements — candidates who practice reasoning MCQs daily find that their accuracy and speed improve substantially within a relatively short preparation period.

General Awareness covers the broad knowledge of current affairs, Indian history, geography, polity, economy, and science and technology that the Railway Recruitment Boards expect from every candidate selected into their workforce. Important developments in Indian Railways itself — new train launches, electrification milestones, station redevelopment projects, safety initiatives, and technological upgrades — carry particular importance in the RRB ALP General Awareness section and reward candidates who follow railway news alongside mainstream current affairs. Static GK covering India's physical geography, constitutional framework, historical landmarks, scientific discoveries, and important national institutions rounds out a General Awareness syllabus that is broad in scope but manageable in depth for candidates who prepare systematically and practice regularly. Consistent daily MCQ practice across every section of the RRB ALP and Technician syllabus on platforms like Vooo AI Education ensures that every aspirant builds the technical mastery, scientific understanding, mathematical accuracy, and examination confidence needed to clear every stage of this competitive examination and secure a proud and rewarding career with Indian Railways.

1ALP in Railways stands for:
A. Assistant Loco Pilot
B. Auxiliary Loco Pilot
C. Assistant Line Pilot
D. Advanced Loco Pilot
Answer: A — Assistant Loco Pilot
ALP (Assistant Loco Pilot) drives trains under the supervision of the Loco Pilot (LP). The RRB ALP examination also recruits Technicians. An ALP can be promoted to Loco Pilot after qualifying required tests and gaining experience. It is one of the most sought-after railway jobs.
2Ohm's Law states V = IR. If V = 12V and R = 4Ω, then I =
A. 2A
B. 3A
C. 4A
D. 6A
Answer: B — 3A
Using Ohm's Law: I = V/R = 12/4 = 3 Amperes. Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, provided temperature and physical conditions remain constant.
3Which type of current is used in homes in India?
A. Direct Current (DC)
B. Alternating Current (AC)
C. Both AC and DC
D. Pulsating DC
Answer: B — Alternating Current (AC)
Homes in India use Alternating Current (AC) at 230 volts and 50 Hz frequency. AC is used because it can be easily transformed to different voltages using transformers, making long-distance transmission efficient. DC is used in batteries and electronic devices.
4The unit of electrical power is:
A. Volt
B. Ampere
C. Ohm
D. Watt
Answer: D — Watt
The SI unit of electrical power is the Watt (W), named after James Watt. Power = Voltage × Current (P = VI). 1 Watt = 1 Joule per second. 1 kilowatt (kW) = 1000 W. Electricity bills are calculated in kilowatt-hours (kWh), also called units.
5What does LCM stand for in mathematics?
A. Lowest Common Multiple
B. Largest Common Multiple
C. Lowest Common Measure
D. Largest Common Measure
Answer: A — Lowest Common Multiple
LCM stands for Lowest Common Multiple (also called Least Common Multiple). It is the smallest positive integer divisible by both numbers. For example, LCM of 4 and 6 is 12. LCM and HCF problems are standard in RRB ALP Mathematics sections.
6Which material is a good conductor of electricity?
A. Rubber
B. Glass
C. Copper
D. Wood
Answer: C — Copper
Copper is an excellent conductor of electricity due to its free electrons. It is widely used in electrical wiring, motors and transformers. Other good conductors include silver (best conductor), gold and aluminium. Rubber, glass and wood are insulators.
7Diesel engines work on which principle?
A. Otto cycle
B. Diesel cycle
C. Carnot cycle
D. Rankine cycle
Answer: B — Diesel cycle
Diesel engines work on the Diesel cycle, where air is compressed to a high pressure causing it to heat up, then diesel fuel is injected and ignites spontaneously. Diesel engines have no spark plugs unlike petrol engines. They are more fuel-efficient and are used in locomotives.
8The boiling point of water at high altitude is:
A. Higher than 100°C
B. Equal to 100°C
C. Lower than 100°C
D. Depends on humidity
Answer: C — Lower than 100°C
At higher altitudes, atmospheric pressure is lower, so water boils at temperatures below 100°C. For example, at the top of Mount Everest, water boils at about 70°C. This is why cooking takes longer at high altitudes.
9If a train travels 240 km in 4 hours, its speed is:
A. 50 km/h
B. 55 km/h
C. 60 km/h
D. 65 km/h
Answer: C — 60 km/h
Speed = Distance / Time = 240 / 4 = 60 km/h. Speed, distance and time problems are very common in RRB ALP Mathematics. Formula: Speed = Distance/Time, Distance = Speed × Time, Time = Distance/Speed.
10Which gas is filled in electric bulbs?
A. Oxygen
B. Nitrogen or Argon
C. Carbon dioxide
D. Hydrogen
Answer: B — Nitrogen or Argon
Electric bulbs are filled with inert gases like nitrogen or argon to prevent the tungsten filament from burning out due to oxidation. The inert gas slows down the evaporation of the filament. CFL and LED bulbs have largely replaced traditional incandescent bulbs.
