NCERT Class 11 History Chapter 4 PDF (Hindi): तीन वर्ग

Chapter 4 of Class 11 History (Hindi Medium), तीन वर्ग, takes us to medieval Europe, where society was divided into three main social groups known as the “Three Orders.” These orders included the clergy (religious leaders), the nobility (land-owning warriors), and the peasants (common people who worked on farms). This chapter explains how these groups lived, worked, and contributed to medieval life. It helps us understand that European society during that period was not only controlled by kings but also by priests, knights, and ordinary farmers who formed the backbone of the economy.

The medieval European system may look different from modern times, yet it teaches us how power, religion, and labour together controlled everyday life. Many students assume history is only about wars and rulers, but this chapter highlights the importance of farmers who grew food, knights who protected lands, and priests who influenced people’s beliefs. This structure defined what people could wear, eat, learn, and even who they could marry. Understanding the Three Orders helps students connect social structure with economics, politics, and religion, giving a clear picture of how people lived before the modern world emerged.

About Chapter 4: Medieval Three Orders (तीन वर्ग)

Medieval European society was organised into three major categories known as Three Orders:

CategoryRole in SocietyExample
Clergy (धार्मिक वर्ग)Provided religious guidance and educationPriests, Bishops
Nobles (युद्ध वर्ग/श्रेष्ठ वर्ग)Protected society and controlled landKnights, Lords
Peasants (कृषि व सामान्य वर्ग)Worked on farms and produced foodFarmers, Labourers

1. Clergy: The Religious Class

  • Controlled churches and monasteries
  • Influenced education, rituals, and social life
  • Collected taxes in the form of tithes
  • Guided kings and nobles on religious matters
  • Enjoyed high respect and authority

2. Nobility: The Warrior Class

  • Owned land and collected taxes from peasants
  • Provided military support to the king
  • Trained as knights with weapons and horseback skills
  • Followed the “Code of Chivalry” (rules of honour and duty)

3. Peasants: The Working Class

  • Worked on large estates called manors
  • Paid rent or taxes to nobles
  • Produced food, raised animals, and made goods
  • Had limited freedom and rights
  • Some peasants were serfs who were bound to the land

Medieval Manor System

The manor was like a small village controlled by a noble. It included:

  • Fields and farms
  • A church and houses
  • Workshops and mills
  • Living quarters for peasants

This system worked as a local economic and social unit.

Change in Social Structure

Over time, trade grew and towns developed. A new group emerged: merchants and artisans, reducing the power of nobles. The rise of cities eventually weakened the medieval structure, leading to modern changes like business, wages, and urban life.

CBSE Class 11 Relations and Functions Question Worksheet: Complete Concept Breakdown and Practice Guide

CBSE Class 11 Relations and Functions Question Worksheet: Complete Concept Breakdown and Practice Guide

This mathematics worksheet on Relations and Functions, prepared for Class 11 CBSE students, is mainly aimed at strengthening fundamentals for school exams and future competitive preparation. It contains 75 multiple-choice questions, covering relations, functions, domain and range, inverse relations, and properties such as reflexive, symmetric, and transitive relations. The questions are framed directly from NCERT-based concepts and focus on logical reasoning rather than lengthy calculations. Overall, the worksheet reflects the type of concept-driven questions students regularly face in board examinations.

I am writing about this worksheet because Relations and Functions is often the chapter where students feel confident initially but end up losing marks due to small conceptual errors. Confusion between relations and functions, incorrect domain restrictions, or misunderstanding range values are very common. A well-structured worksheet like this helps students translate NCERT theory into exam-ready understanding. By carefully analysing the questions, one can clearly see which concepts are tested repeatedly and how simple definitions are converted into scoring MCQs Relations and Functions.

Structure of the Relations and Functions Worksheet

The worksheet consists of 75 MCQs, with each question carrying one mark. The questions are arranged in a way that starts with basic ideas and gradually moves towards more applied concepts. While many questions appear direct, the options are closely framed, which tests clarity of thought and careful reading rather than guesswork.

The overall difficulty level ranges from easy to moderate, making the worksheet suitable for both first-time practice and revision before exams.

Relations and Their Properties

Several questions in the worksheet focus on relations and their mathematical properties. Students are tested on identifying whether a relation is:

  • Reflexive
  • Symmetric
  • Transitive
  • An equivalence relation

Some questions use practical and geometric contexts, such as relations defined on sets of numbers, straight lines, or triangles. These questions check whether students truly understand the meaning of each property instead of memorising definitions Relations and Functions WS 1.

Cartesian Products and Set-Based Relations

The worksheet includes multiple questions based on Cartesian products of sets. Students are asked to:

  • Identify valid ordered pairs
  • Determine domains and ranges of relations
  • Count the number of possible relations between two finite sets

These questions reinforce the idea that a relation is always a subset of a Cartesian product, which is a core concept in this chapter.

Functions and Their Classification

A major portion of the worksheet is dedicated to functions. Questions test whether a given relation qualifies as a function and whether it is:

  • One-one
  • Onto
  • Both one-one and onto
  • Neither one-one nor onto

There are also questions on counting the total number of functions between two finite sets, a topic that frequently appears in CBSE examinations.

Domain and Range-Based Questions

Domain and range form one of the most heavily tested areas in this worksheet. Questions involve functions containing:

  • Square roots
  • Logarithmic expressions
  • Rational functions
  • Modulus functions
  • Trigonometric and inverse trigonometric functions

Students must correctly apply restrictions such as non-negative values under square roots, positive arguments for logarithms, and valid input ranges for inverse trigonometric functions. These questions clearly highlight common error areas faced by students in exams.

Modulus and Greatest Integer Functions

Several questions are based on modulus and greatest integer functions. These problems require interval-wise thinking and careful evaluation of expressions. Instead of direct substitution, students must analyse how the function behaves over different ranges, which helps in developing logical reasoning skills.

Composite and Inverse Functions

The worksheet also includes questions on composite functions and inverse relations. These questions test whether students can apply function rules correctly rather than just recall formulas. Such problems are important because they form the base for advanced topics in calculus studied later.

Trigonometric and Logarithmic Applications

Some MCQs combine trigonometric expressions with logarithmic functions. These questions are slightly tricky and demand step-by-step reasoning. They test conceptual clarity and attention to detail, making them useful not just for board exams but also for future competitive preparation.

What Students Can Learn from This Worksheet

From analysing this worksheet, a few important points become clear:

  • NCERT definitions and examples are the foundation of most questions
  • Domain and range mistakes are a major scoring risk
  • Properties of relations must be clearly understood, not memorised
  • Options are closely framed, so careless reading leads to errors
  • Regular practice improves both speed and confidence

Overall, this Relations and Functions worksheet is a strong practice resource for Class 11 students. It closely reflects CBSE exam expectations and helps students build a solid conceptual base that will be essential for higher-level mathematics in Class 12.
