This set of notes consolidates Simple and Compound Interest formulas and their applications into a single, easy-to-revise reference. One crucial distinction - that Compound Interest calculated half-yearly at an annual rate of r% uses r/2 as the period rate and doubles the number of periods - is a source of frequent errors in banking exams. Aspirants revising for RBI Grade B will find the side-by-side comparison of SI and CI formulas particularly useful during final revision.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Overview of Time & Work
Time & Work problems test a candidate's ability to calculate combined work rates, including scenarios involving alternating workers or partially completed tasks. The LCM method - where total work is set as the LCM of individual completion times - is the fastest approach and is thoroughly explained in these notes. A tricky variant often seen in banking exams involves one worker leaving before the job is finished, and this is addressed with multiple solved examples.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Boats and Streams
Boats and Streams is a specialized application of Speed, Distance, and Time where the medium (water current) either aids or opposes motion. The fundamental relationship - upstream speed = boat speed - current speed, and downstream speed = boat speed + current speed - forms the basis for all problem types in this topic. These notes include solved examples covering round-trip problems and cases where the stream speed is unknown, both of which appear regularly in RBI Grade B Phase 1 papers.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Introduction to Number Series

These notes walk through each problem type systematically, including three-person age problems and ratio-based conditions, with fully worked solutions.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Practice Questions on Alligation & Mixture
Alligation is a technique for finding the ratio in which two ingredients at different prices (or concentrations) must be mixed to produce a mixture at a given price (or concentration). It is far faster than the algebraic method for such problems. These practice questions cover price-based mixtures, replacement problems (where part of a mixture is removed and replaced with a pure component), and income-based alligation - all variants that appear in RBI Grade B Phase 1.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Venn Diagrams
Venn Diagrams provide a visual tool for solving set theory problems involving unions, intersections, and complements of sets. In banking exams, Venn Diagram questions typically involve three overlapping sets and require calculating the number of elements in specific regions - problems where sign errors in the inclusion-exclusion formula are the most common source of mistakes. These notes and question sets together cover the full range of formats in which Venn Diagram problems appear in RBI Grade B Phase 1.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Geometric Progression
A Geometric Progression (GP) is a sequence where each term is obtained by multiplying the previous term by a fixed ratio called the common ratio. GP concepts tested in RBI Grade B Phase 1 include finding the nth term, sum of n terms, and sum of an infinite GP when the common ratio is between -1 and 1. These notes include introduction, key formulas, and solved examples that demonstrate how GP problems are framed in banking exam contexts.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Arithmetic Progression
An Arithmetic Progression (AP) is a sequence where consecutive terms differ by a constant value called the common difference. RBI Grade B questions on AP often involve finding the sum of the first n terms or identifying a specific term given indirect conditions. These notes introduce the standard AP formulas alongside solved examples that show how to extract the first term and common difference from word problems - a skill that separates average scorers from toppers in this section.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Introduction to Indices and Surds
Indices and Surds cover the laws of exponents and operations on irrational numbers expressed as roots. A frequent exam question involves rationalizing the denominator of an expression containing surds - a technique that requires multiplying numerator and denominator by the conjugate. These notes explain all laws of indices (including negative and fractional exponents) and surd rationalization methods, with solved examples that reflect the difficulty level of actual RBI Grade B Phase 1 questions.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Relative Speed
Relative Speed is the concept used when two objects are in motion simultaneously, either towards each other or in the same direction. When moving towards each other, relative speed is the sum of their individual speeds; when moving in the same direction, it is the difference. This concept underpins problems on trains crossing each other, meeting points on circular tracks, and catch-up scenarios - all of which appear regularly in RBI Grade B Phase 1 Quantitative Aptitude.
Notes for RBI Grade B Phase 1 Quantitative Aptitude: Time, Speed and Distance - Problems on Trains
Train problems are a specialized and consistently examined sub-type of Time, Speed, and Distance in banking exams. Key scenarios include a train crossing a stationary object (pole or person), a train crossing a platform, and two trains crossing each other. The most common error is forgetting to add the length of both trains when they cross each other. These notes cover all standard train problem formats with formula derivations and fully solved examples tailored to the RBI Grade B exam pattern.
