RBI began work on 1 April 1935, was nationalised in 1949, and serves as India's central bank and the government's banker, agent and debt manager. Monetary policy changes money, credit and liquidity through repo/reverse repo, bank rate, CRR, SLR and market operations; tighter rates or reserves usually restrain lending and inflation.

• Repo is RBI lending against government securities; reverse repo is RBI borrowing from banks; bank rate is longer-term central-bank lending without collateral.
• CRR is cash held with RBI; SLR is liquid assets such as cash, gold and unencumbered government securities.

GDP values final output produced within domestic territory; value added prevents counting intermediate goods twice. GDP at market prices equals GDP at factor cost plus net indirect taxes, and depreciation converts gross measures to net. NNP at factor cost is National Income, while per-capita income divides National Income by population.

• Transfer payments such as pensions and scholarships are excluded because they pay for no current production; depreciation covers wear, age and obsolescence.
• Primary activities directly use nature: agriculture, forestry, fishing and mining; potential GDP is sustainable full-employment output without inflation.
• HDI combines longevity, education and GNI per head; Gini ranges from 0 (equality) to 1 (maximum inequality).
• The Environmental Kuznets Curve proposes an inverted-U: degradation first rises with income, then may fall after a threshold.

Draw a tiny family tree, mark gender only when stated, and move one generation per parent–child link. Resolve possessives from the speaker outward: 'my grandfather's only son' is the speaker's father, while 'my mother's only daughter' can be the female speaker herself. Translate coded symbols before joining links.

• Siblings share a parent: father of one sibling is father of the other; two parent links upward give grandfather.
• For A+B as father and B−C as mother, A is C's grandfather; avoid changing a person's stated gender.
• Some bank items mixed into this topic use total rank = top + bottom −1, weekday remainder mod 7, simple series and analogies; solve each by its own rule.

Fiscal policy uses taxation, expenditure and borrowing. Fiscal deficit is total expenditure minus revenue receipts and non-debt capital receipts—the borrowing need; revenue deficit is revenue expenditure minus revenue receipts. Revenue spending normally creates no asset, while capital spending creates assets or reduces liabilities.

• Direct-tax impact and incidence fall on the same person; progressive rates rise with income. GST is a destination-based indirect tax on supply and subsumed many central and state levies.
• Capital receipts include borrowings and loan recovery; borrowings create liabilities. Subsidies lower selected producer or consumer costs.

Summer heating creates low pressure over north-west India and draws moisture-bearing south-west winds from the Indian Ocean; the onset reaches Kerala first. Mountains force air upward, cooling it into orographic rain, while descending leeward air creates rain shadow. Wind-direction reversal is the defining monsoon feature.

• Positive Indian Ocean Dipole—warmer west than east—usually strengthens Indian summer rain; Rajasthan stays dry because Aravallis run parallel to the winds.
• Western Ghats give heavy rain to Kerala/Karnataka and a semi-arid leeward interior; the hot dry loo affects north-west India.
• Retreating/north-east monsoon collects Bay moisture and rains on Tamil Nadu's Coromandel Coast, often with Bay cyclones.
• Nor'westers are pre-monsoon storms of Bengal, Assam and nearby eastern India.

At an exact hour, each adjacent clock mark is 30°, so 3:00 gives 90° and 6:00 gives 180°. In 12 hours the hands coincide 11 times and form right angles 22 times; double these for a full day. Calendar shifts reduce the number of elapsed days modulo 7.

• An ordinary 365-day year has one odd day because 365 leaves remainder 1 on division by 7.
• For 'after N days', use N mod 7: 61→5 and Monday+5→Saturday; 17→3 and Monday+3→Thursday.
• At non-exact times use |30h−5.5m| and take the smaller angle if needed.

Most TNPSC coding questions are letter shifts: compare one code letter with its original, count the jump, and verify on a second pair before applying it to the whole word. CAT->DBU, MADRAS->NBESBT and FRIEND->GSJFOE are all +1 shifts (so DOG->EPH, DELHI->EFMIJ, MOTHER->NPUIFS), while PAPER->OZODQ shifts one step BACK (PENCIL->ODMBHK). If shifting fails, test reversal (BOOK->KOOB, so WORD->DROW) and number codes — positional values A=1...Z=26 (CAB = 3+1+2 = 6) or a sequence/letter-count rule.

• Work the offset from ONE pair, confirm on a second: H->I, E->F, A->B, D->E turns HEAD into IFBE — one uniform +1 shift.
• Shifts run backward too: PAPER->OZODQ is -1, so PENCIL codes to ODMBHK; always fix the direction before answering.
• Non-shift patterns, in the order to try them: whole-word reversal (WORD->DROW), A=1...Z=26 positional sums (sum of CAB = 6), then arbitrary sequences ('cat'=3, 'dog'=4, 'fish'=5 makes 'bird'=6).

Answer from the passage, not from outside knowledge. For a direct question, locate the repeated noun and copy its stated fact; for purpose, follow signals such as 'so that'; for vocabulary, replace the word with the option that preserves the sentence. Contrast markers such as 'although' connect opposing ideas.

• Banyan details: aerial roots form extra trunks, the canopy shelters birds/animals, and villagers gather beneath it.
• Farmer details: Ramu rose before dawn, grew paddy, and 'toil' means hard work.

Data sufficiency asks whether the question can be answered uniquely, not whether you can calculate extra information. Test Statement I alone, reset, test II alone, then combine only if neither settles the question. A statement can be sufficient even when the answer to a yes/no question is 'no'.

• Length alone or breadth alone cannot give rectangle area; together they can. A relative age plus the other person's age is likewise a two-statement case.
• Divisible by 4 alone proves even; 2x=12 alone fixes x; a=b+5 alone fixes which is greater.
• Divisibility by 6 needs both divisibility by 2 and by 3; reject irrelevant statements after sufficiency is established.

Fix north on paper and update facing after every turn: clockwise moves N→E→S→W, anticlockwise reverses it. Plot each walk as a vector; cancel opposite legs and use Pythagoras for perpendicular displacement. Morning sun is east, so the shadow falls west.

• A 3-east, 4-north displacement is 5 by the 3–4–5 triangle; 5 north, 3 east, 5 south ends 3 km east.
• Row formulas mixed into this topic: people between seats a,b = |a−b|−1; total = left rank + right rank −1.
• Right rank = total−left rank+1; a vertical mirror reverses left and right, so simplified b becomes d.

Check agreement, comparison and paired conjunctions. 'One/each of the + plural noun' takes a singular verb: one of the boys is; each boy has. News is grammatically singular. Use prefer X to Y and senior to—not 'than'. Use either though/although or but, not both together.

• Say 'my cousin', not the redundant Indian-English form 'cousin brother'.
• Correct patterns: each of the boys has; she is senior to her cousin; I prefer tea to coffee.
• Read the whole sentence before selecting the faulty segment because the correction may depend on its paired word.

CPI measures the household retail basket, and price-index numbers compare price levels over time.

• Stagflation combines high inflation with stagnant or negative growth and high unemployment.
• The short-run Phillips Curve proposes an inverse inflation–unemployment relationship.
• Deflation is a sustained decline—not merely a slower rise—in the general price level.
• Classify a cause before choosing the label: excess spending is demand-pull; increased production cost is cost-push.
