MCQ Class 11 Mathematics Sets with Answers - Set - 5

Question 1: 

Let R= {(x, y) : x, y belong to N, 2x + y = 41}. The range is of the relation R is
(a) {(2n – 1) : n belongs to N, 1 ≤ n ≤ 20}
(b) {(2n + 2) : n belongs to N, 1 < n < 20}
(c) {2n : n belongs to N, 1< n< 20}
(d) {(2n + 1) : n belongs to N , 1 ≤ n ≤ 20}

Correct Answer – (A)
{(2n – 1) : n belongs to N, 1 ≤ n ≤ 20}
Given,
2x + y = 41
⇒ y = 41 – 2x
x : 1 2 3 ………………20
y : 39 37 35 ……………..1
So, range is
{(2n – 1) : n belongs to N, 1 ≤ n ≤ 20}

Question 2 : 

Two finite sets have m and n elements. The total number of subsets of the first set is 56 more than the total number of subsets of the second set. The values of m and n are     
(a) m = 7, n = 6
(b) m = 6, n = 3
(c) m = 5, n = 1
(d) m = 8, n = 7

Correct Answer – (B)

Question 3 : 

Let f be a function on R or R given by f (x) = x2 and let     
E = {x ε R:-1 ≤ x ≤ 0} and
F = {x ε R:0 ≤ x ≤ 1}
then which of the following is false
(a) f (E) = f (F)
(b) E ∩ F Ì f (E) ∩ f(F)
(c) E ∪ F Ì f (E) ∪ f(F)
(d) f (E ∩ F) = {0}

Correct Answer – (C)

Question 4 : 

If X = {8n – 7n -1: nÎN} and Y = {49 (n -1):nÎN} then:     
(a) X ⊆ Y
(b) Y ⊂ X
(c) X = Y
(d) X ∪ Y = N

Correct Answer – (A)

Question 5 :

Question 6 : 

The smallest set a such that A ∪ {1, 2} = {1, 2, 3, 5, 9} is
(a) {3, 5, 9}
(b) {2, 3, 5}
(c) {1, 2, 5, 9}
(d) None of these

Correct Answer – (A)
Given, a set A such that A ∪ {1, 2} = {1, 2, 3, 5, 9}
Now, smallest set A = {3, 5, 9}
So, A ∪ {1, 2} = {1, 2, 3, 5, 9}

Question 7 : 

A = {x : x ¹ x} represents   
(a) {x}
(b) {1}
(c) { }
(d) {0}

Correct Answer – (C)

Question 8 : 

Let F1 be the set of parallelograms, F2 the set of rectangles, F3 the set of rhombuses, F4 the set of squares and F5 the set of trapeziums in a plane.   
Then F1 may be equal to
(a) F2 ∩ F3
(b) F3 ∩ F4
(c) F2 ∪ F5
(d) F2 ∪ F3 ∪ F4 ∪ F1

Correct Answer – (C)
