Basics of Exercise 1.2 Class 11 Maths Solutions

• Equal sets: If there are two sets A and B, both sets are said to be equal sets if there are the same elements in both sets. Equal sets are represented as A=B and unequal sets are represented as A ≠ B
• Null Set: A set that does not have any elements is known as empty set/null set or void set
• Finite & Infinite Set: A set consisting of a definite number of elements is called a finite set and the opposite is known as infinite set

Class 11 Math Chapter 1 Exercise 1.2: Solutions PDF

All the downloadable PDFs for 6 questions from Maths Exercise 1.2 Class 11 are provided for student reference below. It is advisable to take the printouts of the solutions and practice the solutions step-wise to understand the concepts.

Q.1: Whether the given statement is example of the null set or not
Set of odd natural numbers divisible by 2
Ans: The set with zero element is called null set.
We know that no odd number is divisible by 2.
Therefore, it is a null set.

Q.2: Whether the given statement is example of the null set or not
Set of even prime numbers
Ans: The set with zero element is called null set.
2 is an even prime number
Therefore, a set of even prime numbers is not a null set.

Q.3: Whether the given statement is example of the null set or not
{ x:x is a natural number, x<5 and x>7}
Ans: The set with zero element is called null set.
{x:x is a natural number, x<5 and x>7} is a null set because a number cannot be simultaneously less than 5
and greater than 7
