यदि ({a,4}={2,b}) और \(a\ne4\), तो सही युग्म कौन सा है?
If ({a,4}={2,b}) and \(a\ne4\), which pair is correct?
Explanation opens after your attempt
Correct Answer
A. (a=2,\ b=4)
Concept
Equal sets must contain both (2) and (4). Since \(a\ne4\), (a=2) and then (b=4).
Why this answer is correct
The correct answer is A. (a=2,\ b=4). Equal sets must contain both (2) and (4). Since \(a\ne4\), (a=2) and then (b=4).
Exam Tip
बराबर समुच्चयों में (2) और (4) दोनों सदस्य होने चाहिए। \(a\ne4\) से (a=2) और फिर (b=4) होगा।
