Question 31/600 Easy Mathematics Sets Operations on Sets (Union, Intersection, Difference) Class 11 Level 16

यदि \(A=\{2,3,4,5\}\) और \(B=\{1,3,5,7\}\) हैं, तो (n\(A\cap B\)) क्या है?

If \(A=\{2,3,4,5\}\) and \(B=\{1,3,5,7\}\), what is (n\(A\cap B\))?

Explanation opens after your attempt
Correct Answer

A. (2)

Explanation

Simple Explanation

\(A\cap B={3,5}\) है। इसलिए इसमें (2) अवयव हैं। / \(A\cap B={3,5}\). So it has (2) elements.

Question 32/600 Easy Mathematics Sets Operations on Sets (Union, Intersection, Difference) Class 11 Level 16

कौन-सा गुण \(A\cup B=B\cup A\) को दर्शाता है?

Which property is shown by \(A\cup B=B\cup A\)?

Explanation opens after your attempt
Correct Answer

A. क्रमविनिमेय गुणCommutative property

Explanation

Simple Explanation

\(A\cup B=B\cup A\) में क्रम बदलने पर संघ नहीं बदलता। यह संघ का क्रमविनिमेय गुण है। / In \(A\cup B=B\cup A\), changing the order does not change the union. This is the commutative property of union.

Question 33/600 Easy Mathematics Sets Operations on Sets (Union, Intersection, Difference) Class 11 Level 16

कौन-सा गुण \(A\cap B=B\cap A\) को दर्शाता है?

Which property is shown by \(A\cap B=B\cap A\)?

Explanation opens after your attempt
Correct Answer

A. क्रमविनिमेय गुणCommutative property

Explanation

Simple Explanation

\(A\cap B=B\cap A\) में intersection का क्रम बदलने से परिणाम नहीं बदलता। इसे क्रमविनिमेय गुण कहते हैं। / In \(A\cap B=B\cap A\), changing the order of intersection does not change the result. This is called the commutative property.

Question 34/600 Easy Mathematics Sets Operations on Sets (Union, Intersection, Difference) Class 11 Level 16

कौन-सा विकल्प \(A\cup A\) के बराबर है?

Which option is equal to \(A\cup A\)?

Explanation opens after your attempt
Correct Answer

A. (A)

Explanation

Simple Explanation

किसी समुच्चय का अपने साथ संघ वही समुच्चय होता है। इसलिए \(A\cup A=A\) है। / The union of a set with itself is the same set. Hence \(A\cup A=A\).

Which option is equal to \(A\cap A\)?

Explanation opens after your attempt
Correct Answer

A. (A)

Explanation

Simple Explanation

किसी समुच्चय का अपने साथ सर्वनिष्ठ वही समुच्चय होता है। इसलिए \(A\cap A=A\) है। / The intersection of a set with itself is the same set. Hence \(A\cap A=A\).

Question 36/600 Easy Mathematics Sets Operations on Sets (Union, Intersection, Difference) Class 11 Level 16

यदि \(A=\{1,2,3\}\), \(B=\{3,4\}\) और \(C=\{4,5\}\) हैं, तो (\(A\cup B\)\cap C) क्या है?

If \(A=\{1,2,3\}\), \(B=\{3,4\}\), and \(C=\{4,5\}\), what is (\(A\cup B\)\cap C)?

Explanation opens after your attempt
Correct Answer

A. ( {4} )

Explanation

Simple Explanation

पहले \(A\cup B={1,2,3,4}\) निकालें। फिर (C) से सामान्य अवयव (4) है। / First find \(A\cup B={1,2,3,4}\). Then the common element with (C) is (4).

Question 37/600 Easy Mathematics Sets Operations on Sets (Union, Intersection, Difference) Class 11 Level 16

यदि \(A=\{1,2,3,4\}\), \(B=\{2,4,6\}\) और \(C=\{1,2,6\}\) हैं, तो (\(A\cap B\)\cup C) क्या है?

If \(A=\{1,2,3,4\}\), \(B=\{2,4,6\}\), and \(C=\{1,2,6\}\), what is (\(A\cap B\)\cup C)?

Explanation opens after your attempt
Correct Answer

A. ( {1,2,4,6} )

Explanation

Simple Explanation

\(A\cap B={2,4}\) है। इसे (C) से मिलाने पर ({1,2,4,6}) मिलता है। / \(A\cap B={2,4}\). Taking union with (C) gives ({1,2,4,6}).
