\(यदि (U={1,2,3,4,5,6,7,8,9,10}) और (A={x:x\in U\) और \(x^2-5x+6=0}) है, तो (A^c) क्या होगा\)?
\(If (U={1,2,3,4,5,6,7,8,9,10}) and (A={x:x\in U\) and \(x^2-5x+6=0}), what is (A^c)\)?
Explanation opens after your attempt
A. ({1,4,5,6,7,8,9,10})
Concept
From \(x^2-5x+6=0\), (x=2,3). Removing (2) and (3) from (U) gives the complement.
Why this answer is correct
The correct answer is A. ({1,4,5,6,7,8,9,10}). From \(x^2-5x+6=0\), (x=2,3). Removing (2) and (3) from (U) gives the complement.
Exam Tip
\(x^2-5x+6=0\) से (x=2,3) मिलते हैं। (U) से (2) और (3) हटाने पर पूरक मिलता है।
