यदि \(A=\{1,2,3\}\) और \(R=\{(a,b):a+b<3\}\) है, तो (R) क्या होगा?
If \(A=\{1,2,3\}\) and \(R=\{(a,b):a+b<3\}\), what is (R)?
Explanation opens after your attempt
A. \(R=\{(1,1)\}\)
Concept
Only (1+1=2) is less than (3). Hence only ( (1,1) ) will be in (R).
Why this answer is correct
The correct answer is A. \(R=\{(1,1)\}\). Only (1+1=2) is less than (3). Hence only ( (1,1) ) will be in (R).
Exam Tip
केवल (1+1=2) है जो (3) से छोटा है। इसलिए (R) में सिर्फ ( (1,1) ) आएगा।
