9 The set of even prime numbers is (2,4,6,8,10} {2,4,6,8,10,12} {1,3,5,7,9} {2}
10 If A⊆ B, and B is a finite set, then n (a) &lt; n(B) n(B)&lt;(A) n(A)≤ n (B) n(A)≥ n(B)
11 If A = {2m/m3= 8 , m€ Z} then A =

 {1,8,27} {4} (2,4,6} {2,16,54}
12 If 0 = {1,3,5.......}, then n (0) = Infinite Even numbers odd integers 99
13 If B ={x/x€ Z ^ - 3 < x < 6}, then n (B) = 5 {-3,-2,-1,0,1,2,3,4,5,6} 8 9
14 If a = {2m/2m < 9 ,m€ p} , the (n A) = {2,3,4,5,6,7,8} {2,4,6,8............16} { 4, 6} {2,3,5,7}
15 If C={p/p < 18, p is a prime number}, then C = {2,3,4,.........17} {2,4,6,8................16} {1,3,5,7,9,11,13,15,17} {3,6,9,12,15}
16 If A = {x/x is a positive integer and 4≤x<23}, then A= {1,2,3,4,5,6,7} {4,5,6...........22} {1,2,3,.........23} {1,2,3,4,5}
17 Z is a Infinite set Finite set Singleton set Set of all integers
18 {0} is a Empty set Singleton set Zero set Null Set
19 Every set is an improper subset of Empty set Equivalent set Itself Singleton set
20 Empty set is Not subset of every set Finite set Infinite set Not the member of real numbers
21 if A = (x/x€ Q˄ 0 < x < 1}, the A is Infinite set Finite set Set of rational numbers Set of real numbers
22 If there is one-one correspondence between A and B, then we write. A = B A⊆ B A⊇ B A ∼ B
23 P∉ A means <i>P</i>is subset of A <i>P</i>is an element of A <i>P does not belongs to A</i> A does not element of <i>P</i>
24 The set of months in a year beginning with S. {September, October, November} Singleton set Null set Empty set
25 A = B iff All elements of A also the elements of B A and B should be singleton A and B have the same number of elements If both have the same element
26 If P = {x/x = p/q where p,q∈ Z and q≠ 0}, then P is the set of Irrational numbers Even numbers Rational numbers Whole numbers
27 If S = {3,6,9,12.......}, then S = Four multiples of 3 S = Set of even numbers S = Set of prime numbers S = All multiples of 3
28 Which of the following is the definition of singleton The objects in a set A set having no element A set having no subset None of these
29 If T = {2,4,6,8,10,12}, then T = (First six natural numbers) T = (First six odd numbers) T = (First six real numbers) T = ( First six even numbers)
30 Which of the following statement is true? A set is a collection of non-empty object A set is a collection of only numbers a set is any collection of things a set is well-defined collection of objects
