Square Roots for Competitive Exams

The square root of a number 'x' is another number 'y' that when multiplied by itself gives 'x'. For example, 3 is the square root of 9 because 3 × 3 = 9. Grasping this basic concept builds the foundation to excel in the square roots portion of the SSC CGL Tier-I Quantitative Aptitude exam.

Important Details - Square Root Concept

Term Definition
Square Root A number that when multiplied by itself gives the original number
Example The square root of 9 is 3, as 3 × 3 = 9

SSC CGL Tier-I Square Roots Syllabus

The SSC CGL Tier-I square roots syllabus focuses on:

Calculation Methods Finding square roots using division, factorization, tables, approximations and calculators
Applications Applying square roots to calculate distances, areas, volumes, equations etc.
Properties Identifying perfect squares and their special properties

The syllabus requires a combination of conceptual clarity, mastery of different calculation techniques and the ability to apply square roots to solve diverse quantitative problems.

Tips to Master Square Roots

Some useful tips to master square roots for the SSC CGL Tier-I exam include:

Tips Details
Practice Extensively Solve previous year questions, mock tests across various difficulty levels
Focus on Speed & Accuracy Learn quick approximation methods to save time
Use Calculators Strategically Balance traditional manual methods with calculators for efficiency
Develop Number Sense Build intuition for number properties and relationships

Along with extensive practice, developing strategic approaches tailored to the exam pattern is key for success.

Importance in Relation to Quantitative Aptitude Syllabus

While square roots form an integral part of the syllabus, equal importance must be given to other topics like:

Other Important Topics Details
Arithmetic Operations Addition, subtraction, multiplication, division of numbers
Percentages Calculating percentages, conversions, interest, profit/loss etc.
Averages Mean, median, mode calculation
Ratio and Proportion Identifying and solving problems using direct/inverse proportion

By dedicating time across all syllabus areas, strong fundamentals can be built to tackle the exam confidently.


Demystifying the square roots portion is pivotal for SSC CGL Tier-I success. One must grasp the basic concepts, master diverse calculation methods, apply square roots to solve problems, understand special properties and practice extensively. When combined with proficiency across all quantitative topics, you will be able to maximize scores in this critical exam section.


Q1: What is the key thing to understand about square roots?

A1: The key concept is that the square root of a number 'x' is another number 'y' which when multiplied by itself gives 'x'. Grasping this builds foundations to learn calculation methods, applications etc.

Q2: How to master the approximate/quick techniques for finding square roots?

A2: Regular practice by solving previous year questions and mock tests is key. Start with simple approximations and then gradually build up speed and accuracy on difficult problems. Develop familiarity with squares and square roots tables.

Q3: Should calculators be used strategically for square roots in the exam?

A3: Yes, balance manual traditional methods and calculators. Use approximation techniques to get a quick estimate first. Then input the number in calculator to get accurate result. This balances speed and precision.

Q4: How much time should one allocate for square roots preparation?

A4: Allocate 15-20% of your quantitative aptitude preparation time for square roots. Solve previous year questions, appear for regular mock tests. Analyze your weak areas and improve speed and accuracy.

Q5: Is it necessary to remember the table of squares and square roots?

A5: Not mandatory but highly recommended. Memorizing the common squares and roots will help in faster calculation, identification of perfect squares and more accurate approximation. It reduces reliance on calculators.

Q6: What other quantitative topics need focus apart from square roots?

A6: Other important topics are - arithmetic operations, percentages, averages, ratio and proportion, mensuration, data interpretation etc. Build strong conceptual fundamentals across all topics through extensive practice.
