\(यदि (U={x:x \in \mathbb{Z},0 \le x \le 10}) और (A={x:x \in U\) तथा \(x^2-5x+6=0}), तो (A') कौन सा है\)?

\(If (U={x:x \in \mathbb{Z},0 \le x \le 10}) and (A={x:x \in U\) and \(x^2-5x+6=0}), which is (A')\)?

Explanation opens after your attempt
Correct Answer

A. ({0,1,4,5,6,7,8,9,10})

Step 1

Concept

The equation gives (x=2) and (x=3). Removing them from (U) gives the complement.

Step 2

Why this answer is correct

The correct answer is A. ({0,1,4,5,6,7,8,9,10}). The equation gives (x=2) and (x=3). Removing them from (U) gives the complement.

Step 3

Exam Tip

समीकरण से (x=2) और (x=3) मिलते हैं। इन्हें (U) से हटाने पर पूरक मिलता है।
