**Joy of Mathematics Class 6 Solutions Chapter 1 Sets**

Welcome to NCTB Solution. Here with this post we are going to help 6th class students for the Solutions of Joy of Mathematics Class 6 Book, Chapter 1 Sets. Here students can easily find step by step solutions of all the problems for Sets. Exercise wise proper solutions for every problems. All the problem are solved with easily understandable methods so that all the students can understand easily. Here students will find solutions for Exercise 1.1 and 1.2

**Sets Exercise 1.1 Solution**

**Question no – (1)**

**Solution :**

**(a)** It is a set because all the collections of numbers are well defined and distinct

**(b)** It is a set because collection all the numbers between 10 to 20 are well defined 8 distinct

**(c)** No, it is not set because a problem may be defined for one and easy for the other

**(d)** If is not a set because its not well defined

**(e)** It is not a set because its not well defined

**(f)** It is not a set because its not well defined

**Question no – (2) **

**Solution :**

**(a)** 10 **∉** A

**(b)** 11 **∈** A

**(c)** a **∉** A

**(d)** {3) **∉** A

**Question no – (3) **

**Solution :**

**(a)** Given statement is – **False**

**(b)** Given statement is – **True**

**(c)** Given statement is – **True**

**(d)** Given statement is – **False**

**(e)** Given statement is – **True**

**(f) **Given statement is – **True**

**Question no – (4) **

**Solution :**

**(a)** S = (1, 3, 5}

**(b)** S = {2, 4, 6, 8}

**(c)** B = {5, 10, 15, 20, 25, 30, 35, 40, 45}

**(c)** B = {5, 10, 15, 20, 25, 30, 35, 40, 45}

**(d)** A = {1, 2, 3, 4, 6, 8, 12, 16, 24, 48}

**Question no – (5) **

**Solution :**

**(a)** S = {x : x is a natural number, x < 10}

**(b)** S = {x : x is a prime number, x < 100}

**(c)** B = {x : x is a vowel in the word OLYMPIAD

**(d)** S = {x : x is a constant in the word WNITED STATES}

**Question no – (6) **

**Solution :**

**(a)** X = {2, 3, 5, 7, 11, 13, 17, 19}

**(b)** A {21, 22, 23, 24,}

**(c)** A = {0, 1, 2, 3, 4} whole no loss than 5

**(d)** B = {(1, 5, 7, 35} ; { factors of 35}

**(e)** S = {11 22, 33, 44, 55, 66, 77, 88}

**Sets Exercise 1.2 Solution : **

**Question no – (1) **

**Solution :**

**(a)** This sets are **Finite**

**(b)** This sets are **Finite**

**(c)** This sets are **Infinite**

**(d)** This sets are **Finite**

**(e)** This sets are **Finite**

**(f)** This sets are **Finite**

**Question no – (2) **

**Solution :**

**(a)** It is not.

**(b)** It is not.

**(c)** It is empty set.

**(d)** It is not.

**(e)** It is not.

**Question no – (3)**

**Solution :**

**(a)** This is not

**(b)** This pairs sets are equivalent but not equal.

**(c)** This pair of seats are equivalent but not equal

**(d)** This is not.

**(e)** This pair of sets are equivalent but not equal.

**Question no – (4)**

**Solution :**

**(a)** Infinite Set.

**(b)** Finite set.

**(c)** Infinite set

**(d)** Finite set

**(e)** Infinite set

**(f)** Infinite set

**Question no – (5)**

**Solution :**

**(a)** Cardinal number is 4.

**(b)** Cardinal number is 4.

**(c)** Cardinal number is 10.

**(d)** Cardinal number is 9.

**(e)** Cardinal number is 0.

**(f)** Cardinal number is 1.

**Question no – (6) **

**Solution :**

**(a)** Given statement is – **False**

**(b)** Given statement is – **False**

**(c)** Given statement is – **False**

**(d)** Given statement is – **False**

**(e)** Given statement is – **False**

**(f)** Given statement is – **True**

**(g)** Given statement is – **True**

**Question no – (7) **

**Solution :**

Given A = {5, 7, 9, 2, 3} B = {3, 5, x, 2, 7} If A = B Conjuring = x = 9

**Question no – (8) **

**Solution :**

**(a)** A = {x | x ∈ w, x < 15 and, B = x = x is a Factor From this, This is overlapping set

**(b)** A = {x | x is a constant in the words ‘MATHS’ and, B = {x | x is a vowel in the word {PHYSICS} From this, the given sets A and B are disjoint set.

**(c)** Here, A and B are overlapping set.
