यदि \(U={1,2,\ldots,15}\), \(A=\{1,2,3,4,5\}\), \(B=\{4,5,6,7,8\}\) और \(C=\{7,8,9,10\}\), तो (\(A\cup B\cup C\)') क्या है?

If \(U={1,2,\ldots,15}\), \(A=\{1,2,3,4,5\}\), \(B=\{4,5,6,7,8\}\), and \(C=\{7,8,9,10\}\), what is (\(A\cup B\cup C\)')?

Explanation opens after your attempt
Correct Answer

A. ({11,12,13,14,15})

Step 1

Concept

The union of the three sets is \({1,2,\ldots,10}\). Removing it from (U) leaves ({11,12,13,14,15}).

Step 2

Why this answer is correct

The correct answer is A. ({11,12,13,14,15}). The union of the three sets is \({1,2,\ldots,10}\). Removing it from (U) leaves ({11,12,13,14,15}).

Step 3

Exam Tip

तीनों का संघ \({1,2,\ldots,10}\) है। (U) से हटाने पर ({11,12,13,14,15}) बचता है।
