\(यदि (U={1,2,3,\ldots,12}) और (A={x:x\in U\) और \(x^2-7x+12=0}) है, तो (A^c) क्या होगा\)?
\(If (U={1,2,3,\ldots,12}) and (A={x:x\in U\) and \(x^2-7x+12=0}), what is (A^c)\)?
Explanation opens after your attempt
A. ({1,2,5,6,7,8,9,10,11,12})
Concept
From \(x^2-7x+12=0\), (x=3,4). Removing (3) and (4) from (U) gives \(A^c\).
Why this answer is correct
The correct answer is A. ({1,2,5,6,7,8,9,10,11,12}). From \(x^2-7x+12=0\), (x=3,4). Removing (3) and (4) from (U) gives \(A^c\).
Exam Tip
\(x^2-7x+12=0\) से (x=3,4) मिलते हैं। (U) से (3) और (4) हटाने पर \(A^c\) मिलता है।
