IDBI Bank ESO cheat sheet

RBI was established on 1 April 1935 under the RBI Act, 1934, and nationalised on 1 January 1949; it is India's monetary authority, banker to the government and lender of last resort.

Policy repo rate is the rate at which RBI lends to banks against government securities under LAF; reverse repo absorbs liquidity, SDF (introduced April 2022) is the floor of the LAF corridor and MSF the ceiling.

CRR is the share of NDTL kept as cash with RBI and earns no interest; SLR is held in government securities and other approved assets and does earn interest.

Priority Sector Lending target for domestic scheduled commercial banks is 40% of ANBC (or off-balance-sheet exposure, whichever is higher), with sub-targets of 18% for agriculture and 7.5% for micro enterprises.

Basel III capital ratios for Indian banks: minimum CET1 5.5%, Tier 1 7%, total CRB 9%, plus a capital conservation buffer of 2.5% taking the effective total to 11.5%.

Banking Regulation Act, 1949 governs banking companies; RBI Act, 1934 governs monetary policy and currency; a banking licence is issued under Section 22 of the BR Act.

Key regulators: SEBI (securities), IRDAI (insurance), PFRDA (pensions), IBBI (insolvency), IFSCA (GIFT City); NPCI operates UPI, IMPS, RuPay, NACH and FASTag.

IBC 2016 sets a 330-day outer limit for corporate insolvency resolution including extensions; SARFAESI Act 2002 allows secured creditors to enforce security without court intervention.

Direct taxes are levied on income and wealth (income tax, corporate tax, capital gains); indirect taxes are on consumption - GST, customs duty - with GST having CGST, SGST/UTGST and IGST components.

Simple interest = PRT/100; compound interest = P(1 + R/100)^T − P. For two years, CI − SI = P(R/100)², and for three years CI − SI = P(R/100)²(3 + R/100).

Effective annual rate for compounding n times a year = (1 + R/n)^n − 1; if a sum doubles in T years at simple interest, R = 100/T percent per annum.

Profit and loss: profit% = profit/CP × 100; a dishonest dealer's gain% = error/(true weight − error) × 100; successive discounts of a% and b% equal a + b − ab/100.

Speed conversions: 1 km/h = 5/18 m/s; for a train of length L crossing a platform of length P at speed S, time = (L + P)/S; relative speed adds for opposite directions and subtracts for same direction.

Ratio and mixtures: alligation rule gives ratio of quantities = (mean − cheaper) : (dearer − mean); if a vessel of volume V has x litres replaced by water n times, final pure liquid = V(1 − x/V)^n.

Time and work: if A does work in a days and B in b days, together they take ab/(a + b) days; work done is inversely proportional to time, and efficiency ratios invert time ratios.

Permutation and combination: nPr = n!/(n − r)!; nCr = n!/(r!(n − r)!); number of diagonals of an n-sided polygon = n(n − 3)/2.

Mensuration: cylinder volume = πr²h, curved surface = 2πrh; cone volume = (1/3)πr²h; sphere volume = (4/3)πr³, surface = 4πr²; equilateral triangle area = (√3/4)a².

Averages and percentages: new average after adding a value = (old average × n + value)/(n + 1); if a number increases by x% then decreases by x%, net change is a decrease of x²/100 percent.

Syllogism: 'All A are B' converts to 'Some B are A'; 'No A is B' converts to 'No B is A'; 'Some A are B' converts to 'Some B are A'. 'Some A are not B' has no valid conversion.

In syllogistic conclusions, a possibility statement ('Some A being B is a possibility') is false only when it contradicts a definite given relation; otherwise treat it as true.

Coding-decoding: check letter positions (A = 1 … Z = 26), opposite letters (sum 27), and shifts separately for each letter of the word before assuming a single rule.

Blood relations: draw a family tree with symbols; vertical lines for generations, horizontal for siblings/marriage. 'Only son of my grandfather' can be the speaker's father or the speaker himself if no siblings exist.

Direction sense: use a coordinate grid; after a sequence of turns compute net displacement, and remember the Pythagorean theorem for the shortest distance (e.g., 3 km north then 4 km east = 5 km).

Ordering and ranking: if a person is nth from the left and mth from the right, total = n + m − 1; to find the number between two people, subtract positions and then subtract 1.

Seating arrangement: fix the person with the maximum definite information first; for circular arrangements facing the centre, left means clockwise and right means anticlockwise.

Inequality: in 'A > B ≥ C', the conclusion 'A > C' follows; conclusions with 'either-or' apply when two conclusions are individually false but complementary (e.g., A ≥ B and A < B).

Data sufficiency: decide after each statement whether the answer is uniquely determined; do not solve fully - stop as soon as sufficiency is established.

Subject-verb agreement: 'one of + plural noun' takes a singular verb; 'either/neither/each/every' take singular verbs; 'none' may be singular or plural depending on the noun it refers to.

Articles: 'a' before consonant sounds (a university, a one-rupee coin), 'an' before vowel sounds (an hour, an MBA); the definite article is used with superlatives and unique objects.

Prepositions: 'since' with a point of time, 'for' with a duration; 'between' for two, 'among' for more than two; 'comprise' takes no 'of' (the class comprises 40 students).

Tenses: present perfect ('has done') for an action with present relevance; past perfect ('had done') for the earlier of two past actions; 'if' clauses use present for real conditions and past for unreal ones.

Conditionals and subjunctives: after 'wish', 'as if', 'if only' use past subjunctive ('were'); after 'had better', 'would rather' use the bare infinitive.

Active to passive: object becomes subject, verb becomes 'be + past participle', and the agent is introduced by 'by'; intransitive verbs have no passive form.

Common confusions: 'affect' (verb) vs 'effect' (noun); 'principal' (main/head) vs 'principle' (rule); 'lie/lay', 'its/it's', 'complement/compliment' - check part of speech before choosing.

Cloze and error spotting: look for parallel structure in lists, misplaced modifiers (a modifier must sit next to what it modifies), and redundancy such as 'return back' or 'discuss about'.

Reading comprehension: answers must be supported by the passage, not by general knowledge; identify the main idea from the first and last sentences of each paragraph and watch for 'except' and 'not' in the question stem.
