यदि \(A=\{2,3,4,5\}\) पर \(R=\{(a,b):a-b=1\}\), तो (R) का प्रांत क्या है?
If \(R=\{(a,b):a-b=1\}\) on \(A=\{2,3,4,5\}\), what is the domain of (R)?
Explanation opens after your attempt
B. ( {3,4,5} )
Concept
The condition gives pairs ( (3,2),(4,3),(5,4) ), so the domain is ( {3,4,5} ). In exams, take first components for domain.
Why this answer is correct

Exam Tip
शर्त से युग्म ( (3,2),(4,3),(5,4) ) बनते हैं, इसलिए प्रांत ( {3,4,5} ) है। परीक्षा में domain के लिए पहले घटक लें।
