यदि \(R=\{(1,1),(1,2),(2,2)\}\) है, तो transitive check में ( (1,2) ) और ( (2,2) ) से कौन-सा pair चाहिए?

If \(R=\{(1,1),(1,2),(2,2)\}\), which pair is needed from ( (1,2) ) and ( (2,2) ) in transitive check?

Explanation opens after your attempt
Correct Answer

A. ( (1,2) )

Step 1

Concept

From ( (a,b)=(1,2) ) and ( (b,c)=(2,2) ), we need ( (a,c)=(1,2) ). This pair is already present.

Step 2

Why this answer is correct

The correct answer is A. ( (1,2) ). From ( (a,b)=(1,2) ) and ( (b,c)=(2,2) ), we need ( (a,c)=(1,2) ). This pair is already present.

Step 3

Exam Tip

( (a,b)=(1,2) ) और ( (b,c)=(2,2) ) से ( (a,c)=(1,2) ) चाहिए। यह pair पहले से मौजूद है।
