• A is a list of any five prime numbers
• B is a list of first five prime numbers
• C is a list of intelligent people in India
a) B b) C c) A d) None of these

View Answer

Solution: B is the correct answer because the first five prime numbers are well-defined, so it forms a set.

2. Which of the following is not a set builder form of A = {2,4,6,8,10}?
a) A = {x : x is an even number}
b) A = {x : x = 2n, n ≤ 5, n ∈ ℕ}
c) A = {x : x ∈ group of first five even numbers}
d) A = {x : x is an even number, x < 12}

View Answer

Solution: a) is not correct because it represents all even numbers, not only {2,4,6,8,10}.

3. Which of the following is a roster form of B = {x : x = 2n, x < 10, n ∈ W}?
a) B = {2,4,6,8}
b) B = {2,4,8,16,32}
c) B = {1,2,4,8}
d) B = {2,4,8}

View Answer

Solution: c) B = {1,2,4,8} since 20=1, 21=2, 22=4, 23=8.

4. If R = {2,3,5,7}, then which of the following is not true?
a) 6 ∉ R
b) 7 ∈ R
c) 2 ∉ R
d) 3 ∈ R

View Answer

Solution: c) 2 ∉ R is not true because 2 ∈ R.

5. Statement-A: 11 ∈ P and Statement-B: P = {x : x is a prime number}, then which of the following is true?
a) Statement A is always true
b) Statement A is always false
c) Statement A is true, if Statement B is true
d) Statement A is false, even if Statement B is true

View Answer

Solution: c) Since 11 is a prime number, Statement A is true if Statement B is true.

6. Match the following:

List-1
A. P = {1,3,5,7}
B. Q = {2}
C. R = ∅
D. S = {2,3,5,7}

List-2

3. Set of first four odd numbers
4. Set of even prime numbers

a) A-2, B-1, C-4, D-3
b) A-3, B-1, C-2, D-3
c) A-2, B-4, C-1, D-3
d) A-3, B-4, C-1, D-2

View Answer

Solution: c) A-2, B-4, C-1, D-3.

7. If μ is universal set and ∅ is null set, then which of the following is true?
a) ∅ ∈ μ
b) ∅ ⊂ μ
c) μ ⊂ ∅
d) ∅ ⊄ μ

View Answer

Solution: b) ∅ ⊂ μ is always true.

8. If ∅ is a null set, then which of the following is true?
a) ∅ = {0}
b) ∅ = {∅}
c) ∅ = { }
d) ∅ = {{ }}

View Answer

Solution: c) ∅ = { } represents the empty set.

9. Which of the following are not infinite sets?
A = {x : x ∈ ℕ}
B = {x : x is a multiple of 5}
C = {x : x is a factor of 15}

a) Only A
b) Only B
c) Only C
d) Only B and C

View Answer

Solution: c) Only C, because factors of 15 are finite.

10. If A = {x : x is a multiple of 2}, then which of the following is not a subset of A?
a) {x : x is a multiple of 4, x < 40}
b) {x : x is a multiple of 6, x < 60}
c) {x : x is a multiple of 8, x < 80}
d) {x : x is a multiple of 9, x < 90}

View Answer

Solution: d) Multiples of 9 are not necessarily multiples of 2.

11. Which of the following are not equal sets?
a) {x : x is a letter from the word MADAM} and {x : x is a letter from the word DAM}
b) {x : x is even number} and {x : x is a number divisible by 2}
c) {x : x is a square number, x < 16} and {x : x is a square number, x < 15}
d) {x : x is a prime number, x < 8} and {x : x is an odd number, x < 8}

View Answer

Solution: d) because prime numbers less than 8 are {2,3,5,7} while odd numbers less than 8 are {1,3,5,7}.

12. What does the shaded region represent in the Venn diagram?
