ACE Quant (3rd Edition) by Adda247: A Comprehensive Guide for Banking & Insurance Examinations
The "ACE Quant" (Quantitative Aptitude) 3rd Edition, published by Adda247 Publications, is a highly comprehensive and structured textbook specifically designed to prepare aspirants for the Quantitative Aptitude section of major competitive banking and insurance examinations in India.
This book is widely recognized for its in-depth coverage, extensive practice material, and alignment with the latest examination trends, making it an essential resource for candidates aiming for success in exams like SBI PO/Clerk, IBPS PO/Clerk, RBI Grade B/Assistant, NABARD, LIC, GIC, UIIC, and is also explicitly stated to be useful for the NRA CET (National Recruitment Agency Common Eligibility Test).
Key Features and Pedagogical Structure
The ACE Quant book is built on a robust pedagogical model designed to take a student from basic concepts to advanced problem-solving, which is necessary for both Prelims and Mains exams.
- Exhaustive Question Bank: The book features a massive collection of practice questions, advertised as 2700+ to over 3000+ Multiple Choice Questions (MCQs).
- 100% Detailed Solutions: Every question is accompanied by a detailed solution and explanation, ensuring that the student not only finds the correct answer but also understands the underlying concepts and faster calculation methods.
- Level-Based Progression: The content is strategically divided to match the difficulty levels of the two stages of banking exams (Prelims and Mains). The topics are split into three levels of exercises: Level-1 and Level-2 typically for Prelims, and a separate section for Mains level questions. This systematic approach allows aspirants to build foundational skills before tackling complex, advanced problems.
- Inclusion of Previous Years’ Questions: A significant feature is the inclusion of questions previously asked in various Banking & Insurance Exams, providing students with a realistic gauge of the exam pattern and question types.
- Concepts and Detailed Approach: Each chapter begins with a clear, detailed explanation of concepts, definitions, formulae, and solved examples, allowing for a strong theoretical foundation.
Detailed Content Coverage (Topic-wise Breakdown)
The book systematically covers all topics prescribed in the syllabus for the Quantitative Aptitude section of Bank and Insurance examinations. The overall structure is divided into two primary sections: Speed Maths (foundational concepts) and Arithmetic (advanced word problems), followed by modern topics like Data Interpretation.
Part 1: Foundational and Speed Maths
This section is crucial for improving calculation speed and accuracy, which is essential for the time-bound Prelims exam.
1. Number System, Simplification, and Approximation
This introductory chapter forms the backbone of all mathematical calculations. The detailed coverage includes:
- Classification of Numbers: Explaining types such as Natural, Whole, Integers, Rational, Irrational, Even, Odd, Prime, and Composite Numbers.
- Fundamental Algebraic Formulae: A revision of key identities like (a+b)2, (a-b)2, a2-b2, a3+b3, etc.
- Divisibility Tests: Detailed rules for divisibility by numbers like 2, 3, 4, 5, 6, 8, 9, 11, and 19.
- LCM and HCF: Methods for finding the Least Common Multiple and Highest Common Factor for both integers and fractions.
- Simplification (BODMAS Rule): Application of the BODMAS/PEMDAS rule, detailing the strict order of operations: Bracket, Of, Division, Multiplication, Addition, Subtraction.
- Approximation: Techniques for approximating values in calculations, a common question type in banking exams, including rounding rules (e.g., 3.009 ≈ 3; 4.45 ≈ 4.50).
- Calculation Tricks: The book dedicates space to mental math shortcuts, such as quick multiplication by powers of 5, squaring numbers ending in 5, multiplying numbers near 100, and fast multiplication of multi-digit numbers.
Part 2: Core Arithmetic Topics
The core of the Quantitative Aptitude section, especially for Mains, is covered by these word problem topics:
- Ratio, Proportion and Partnership: Covering basic ratio concepts, comparison of fractions, continued proportion, and the application of ratio in partnership business scenarios.
- Percentage: Explaining the definition, conversion of fractions to percentages, and various formulas for percentage increase/decrease, followed by application in expenditure and population problems.
- Profit and Loss: Detailed study of Cost Price (CP), Selling Price (SP), Marked Price (MP), successive discounts, and dishonest dealer problems.
- Simple Interest and Compound Interest: Covering the formulas and concepts for both SI and CI, including questions on installment payments and the difference between CI and SI for different time periods.
- Average: Focus on calculating simple and weighted averages, average speed, and problems involving replacement of items or people.
- Time and Work: Classic problems involving efficiency, individual and group work, and concepts like wages based on work done.
- Pipe and Cistern: A specialized application of Time and Work, focusing on pipes filling and emptying a tank.
- Speed, Time and Distance: Comprehensive coverage of concepts like relative speed, trains, and solving problems based on various unit conversions.
- Boat and Stream: Dealing with the concept of speed in still water, speed of the current, and calculating upstream and downstream speeds.
- Mixture and Alligation: Explaining the rule of alligation for finding the ratio in which two or more ingredients are mixed, and successive removal/replacement problems.
Part 3: Advanced and Miscellaneous Topics (Implied)
While the full table of contents is not available in the snippets, a complete Quantitative Aptitude book for bank exams would also extensively cover:
- Quadratic Equations and Linear Equations: Comparative analysis of variables based on roots of equations (a staple in Prelims).
- Data Interpretation (DI): Practice on various forms of DI, including Tabular, Bar Graph, Line Graph, Pie Chart, and Caselets (Paragraph-based DI), with a focus on Mains-level complex and integrated DI sets.
- Data Sufficiency (DS): Questions where the student must determine if the given statements are sufficient to answer a question, covering topics from the entire syllabus.
- Permutation & Combination and Probability: Advanced arithmetic topics that are frequently asked in the Mains examination.
- Mensuration: Formulas and problems related to area, perimeter, and volume of 2D and 3D shapes (e.g., circles, spheres, cones, cylinders, cubes).
Utility and Purpose of the Book
The ACE Quant 3rd Edition serves as a complete, single-source preparation material. Its primary utility lies in:
- Structured Learning: Providing structured content with detailed theory and examples, it guides the student through the concepts in a logical and easy-to-understand manner.
- Exam-Specific Focus: The book is meticulously updated as per the latest examination pattern, ensuring that the student is practicing relevant question types and difficulty levels.
- Self-Assessment and Improvement: With thousands of practice questions and detailed solutions, candidates can continuously test their knowledge, identify weak areas, and understand the correct, efficient problem-solving method.
In conclusion, the "ACE Quant" by Adda247 is a highly recommended and robust study aid, acting as a complete preparation kit that combines foundational concept-building with extensive, multi-level practice material crucial for succeeding in the quantitative section of competitive banking and insurance exams.
