Arithmetical Reasoning for Tier-I Exam Preparation

Understanding Arithmetical reasoning is key to cracking the SSC CGL exam. This 3000-word guide covers what it is, tips to prepare, and FAQs.


The Staff Selection Commission Combined Graduate Level (SSC CGL) exam tests candidates on four sections in Tier-I, with arithmetical reasoning being a crucial one that is often overlooked. Going beyond basic math, it evaluates one's ability to analyze numeric patterns, apply arithmetic operations, solve numerical word problems, and reason number relationships.

With practice and a grasp of fundamentals, even those less comfortable with math can master this section. This 3000-word guide will elaborate on what arithmetical reasoning entails in SSC CGL Tier-I, preparation tips, and address frequently asked questions.

Scope of Arithmetical Reasoning in SSC CGL Tier-I

Arithmetical reasoning aims to test the following abilities:

  • Identifying patterns and sequences in number arrangements
  • Applying basic math operations like addition, subtraction etc. in real-life cases
  • Solving word problems containing numerical information
  • Analyzing number relationships to draw logical conclusions

The concepts involved are based mainly on fundamentals covered till Class 10. However, merely memorizing formulas won't suffice. One needs conceptual clarity and sound problem-solving approaches.

Preparation Tips and Strategies

Here are some key tips to master this section:

  1. Revise math basics thoroughly - fractions, decimals, ratios etc.
  2. Practice extensively with previous years' papers to identify patterns
  3. Develop quick mental math ability for time-bound environment
  4. Focus on speed and accuracy through regular timed drills
  5. Invest in quality prep resources like books, online tests etc.

Consistency is vital. Understand your weak areas and keep polishing through practice.

Important Areas to Focus On

Some key topics to master include:

Number Series Fractions & Decimals Percentages
Ratios & Averages Interest & Time Profit & Loss, Discount
Algebra, Geometry Data Interpretation Mensuration

Excel in these through regular practice to gain an edge in the exam.

Develop Effective Problem Solving

Approaching word problems methodically is key, including steps like:

  • Understanding all given details
  • Identifying what needs to be found
  • Relating given data to get equation
  • Solving concisely step-wise
  • Cross-checking final answer

Learn these strategies and practice implementing them through mock tests.

SSC CGL Exam Level of Difficulty

The exam difficulty level varies from basic concepts to complex analytical questions:

  • Easy - Basic calculations tested
  • Moderate - Applications of arithmetic concepts
  • Difficult - Advanced problems on permutations, combinations, number series.

Time management becomes critical for candidates to maximize easy-moderate questions and tackle as many difficult ones before time runs out.


Through regular practice and a clear grasp of underlying concepts, mastering arithmetical reasoning for SSC CGL is achievable for any candidate. Focus on fundamentals, problem-solving strategies and timed drills to gain an edge. Approach this with diligence and use quality prep materials to cement your understanding.

Q1: How does arithmetical reasoning differ from regular quantitative aptitude?

A1: It focuses more on arithmetic application and number analysis than complex formulas. Questions test fundamental concepts in unique contexts.

Q2: Does it require higher level math?

A2: No, elementary math up to 10th grade forms the bulk of this section. But clear conceptual understanding and logical reasoning are tested.

Q3: What patterns are seen in previous year papers?

A3: Number series, simplification/calculation, percentage based questions, profit-loss, time-work have been recurrent.

Q4: How should one select study materials?

A4: Focus on SSC CGL exam-oriented resources with past papers, mock tests and questions aligned to actual pattern.

Q5: What role does speed play?

A5: Very crucial, as attempting maximum questions accurately in limited time impacts scores. Hence regular timed practice is a must.

Q6: What mistakes should one avoid?

A6: Careless errors in calculations, lack of time management, not revising concepts from basics and taking up difficult questions first.
