Roster form with inequalities

असमानताओं सहित रोस्टर रूप

In this Class 11 Mathematics topic from the Sets chapter, students learn how to represent a set in roster form when its elements are defined by inequalities. They practise interpreting conditions such as x < 5 or 2 ≤ x ≤ 6, identifying the appropriate number system, and listing every element clearly within braces. The topic also strengthens understanding of finite sets, endpoints, and the difference between a rule that defines a set and its explicit roster representation.

Practice questions

What is the roster form of B = {x : x is a natural number and 8 ≤ x ≤ 11}?What is the roster form of I = {x : x is a natural number and 12 < x < 16}?
