Number series: test differences, then ratios; alternating series split into odd and even positions before applying a rule.

Coding-decoding: convert letters to positions A=1...Z=26; common shifts are +1, -1, reverse alphabet (A<->Z), and position-sum codes.

Blood relations: draw a family tree; use '+' for male, '-' for female, horizontal line for siblings, vertical line for parent-child; 'only son of my mother' = the speaker himself (if male).

Direction sense: fix north at top; right turn = clockwise 90 degrees; use Pythagoras for shortest distance (3-4-5 and 5-12-13 triples recur).

Syllogism: apply Venn diagrams; 'All A are B' does not imply 'All B are A'; a conclusion is valid only if true in every possible diagram.

Analogy and classification: identify the relation type (part-whole, cause-effect, worker-workplace, synonym/antonym) before choosing the pair.

Seating arrangement: for a circle, note facing centre (left = clockwise) versus facing outward (left = anticlockwise); fix one person and place others relative.

Clock and calendar: hands coincide every 65 5/11 minutes; a normal year shifts the day by 1, a leap year by 2; odd-day method solves day-of-week questions.

Percentage change: successive changes of a% and b% give net change = a + b + ab/100; for decrease use negative values.

Profit and loss: profit% = (SP - CP)/CP x 100; discount% is always calculated on marked price, profit% on cost price.

Simple and compound interest: SI = P x R x T/100; CI amount = P(1 + R/100)^T; for 2 years CI - SI = P(R/100)^2.

Time, speed and distance: speed = distance/time; conversion 1 km/h = 5/18 m/s; for a train crossing a platform, distance = train length + platform length.

Boats and streams: downstream speed = boat + stream, upstream = boat - stream; boat speed = (down + up)/2, stream = (down - up)/2.

Time and work: if A does work in x days and B in y days, together they take xy/(x + y) days; use LCM of days as total work units.

Averages: average = sum/count; if every item increases by k, the average increases by k; weighted average = sum of (value x weight)/sum of weights.

Mensuration: area of circle = pi r^2, circumference = 2 pi r; volume of cylinder = pi r^2 h; volume of cone = (1/3) pi r^2 h; 1 hectare = 10,000 sq m.

SI units: force in newton (kg m/s^2), work/energy in joule, power in watt, pressure in pascal, frequency in hertz; g is about 9.8 m/s^2.

Newton's laws: a body stays at rest or uniform motion unless acted on by a net force; F = ma; every action has an equal and opposite reaction.

Electricity: Ohm's law V = IR; power P = VI = I^2 R; resistors in series add, in parallel 1/R = 1/R1 + 1/R2; household supply in India is 220 V, 50 Hz AC.

Light: reflection angle of incidence equals angle of reflection; convex lens converges, concave diverges; myopia corrected by concave lens, hypermetropia by convex.

Chemistry basics: pH below 7 acidic, 7 neutral, above 7 basic; common salt is NaCl; baking soda NaHCO3; washing soda Na2CO3.10H2O; quicklime CaO.

Periodic table: atomic number = number of protons; group 1 alkali metals, group 17 halogens, group 18 noble gases; metals lose electrons to form cations.

Human body: heart has four chambers; normal adult pulse 60-100 per minute; lungs exchange gases in alveoli; the liver secretes bile; blood groups A, B, AB, O with Rh factor.

Diseases and vitamins: malaria from Plasmodium via female Anopheles mosquito; dengue via Aedes aegypti; deficiency of vitamin A causes night blindness, vitamin C scurvy, vitamin D rickets.

Indian Railways is Asia's largest rail network by route length among national systems; first train in India ran 16 April 1853 from Bori Bunder (Bombay) to Thane, about 34 km.

Establishment: Railway Servants (Discipline and Appeal) Rules 1968 govern penalties; minor penalties include censure, withholding of increments, recovery; major penalties include reduction to lower grade, removal, dismissal.

Leave rules: Railway Servants (Pass) Rules and Liberalised Active Leave Rules apply; casual leave is normally 8 days a year, and leave account rules follow the Railway Services (Liberalised Leave) Rules 1949.

Pass rules: Railway Servants (Pass) Rules 1986 provide privilege passes and PTOs; entitlement depends on pay level and length of service, with set numbers of sets per calendar year.

Hours of work: statutory maximum 10 hours a day and 54 hours a week for continuous/ intensive staff under the Hours of Employment Regulations; running staff have separate kilometre-based limits.

Medical categories: A1, A2, B1, B2, C1, C2 determine fitness for posts; A1 is the highest visual standard for loco pilots and guards, C2 for certain indoor posts.

Welfare: Staff Benefit Fund, Railway Schools, Railway Hospitals, and the Railway Recruitment Boards (RRBs) conduct recruitment; RRC handles Level-1 recruitment.

Grievance and conduct: Railway Services (Conduct) Rules 1966 regulate behaviour; DAR 1968 inquiry requires a charge sheet, defence statement, and inquiry report before major penalty.

Absolute block system: only one train in a block section at a time; the block instrument must show 'Line Clear' before a train is admitted, and 'Train Out of Section' restores normal.

Line clear conditions: preceding train must have cleared the block section and the block instrument must be normal; for long block sections, line clear can be given when the train has passed the home signal of the next station.

Signals: stop signals (home, starter, advanced starter) must be at danger by default; a 'proceed' aspect authorises movement; a calling-on signal permits entry into an occupied section at restricted speed.

Speed limits: 15 km/h when passing a signal at danger under authority (T/369(3b)), 10 km/h in sidings, and 8 km/h when shunting over points; restricted speed always applies in fog.

Fog working: use detonators (3 in number, 10 m apart, 10 m ahead of the signal), fog signalmen, and 'fog' signal aspects; the 'Fog Signal Passed without Caution' rule applies if detonators explode.

Defective signals and track: a defective signal is protected by a banner flag, detonators, and a written memo; a rail fracture is protected by red flags/detonators and reported to the Section Controller.

Accident classification: 'Averted collision', 'collision', 'derailment', 'fire', and 'breach of block rules' are reportable; the Section Controller must inform the Control Office and record in the Train Register.

Caution orders and speed restrictions: issued in writing (or by recorded telephone/message) and confirmed by the driver; engineering 'caution orders' must be acknowledged before the train leaves the station.

Ticket types: ordinary, return, season, and platform tickets; a passenger travelling without a ticket is charged under Section 137 of the Railways Act 1989 with a penalty fare.

Official Language policy: Section 3(3) of the OL Act requires documents in both Hindi and English; correspondence with states in Region A is in Hindi, Region B in Hindi or English, Region C in English.

Railway Official Language: the Railway Board's OL section issues targets for Hindi correspondence; the Department of Official Language (Rajbhasha Vibhag) monitors compliance.

Grammar: subject-verb agreement, use of articles (a/an/the), prepositions, and tense consistency are common test areas; 'an' precedes vowel sounds, 'a' precedes consonant sounds.

Hindi grammar: sangya (noun), sarvanam (pronoun), visheshan (adjective), kriya (verb); ling (gender), vachan (number), and kaal (tense) must agree.

Translation practice: technical railway terms keep standard equivalents, e.g. 'block section' = 'block khanda', 'signal' = 'signal', 'guard' = 'guard'; avoid literal word-for-word translation.

Idioms and phrases: 'at the eleventh hour' = at the last moment; 'to blow the whistle' = to signal a stop; 'in the nick of time' = just in time.

Precis and letter writing: keep official letters formal, with reference number, date, subject, and signature block; a precis retains only the central idea in about one-third of the original length.
