\(यदि (U={1,2,3,4,5,6,7,8,9,10,11,12}) और (A={x:x\in U,x\) divides 12}) है, तो (A') क्या है?

\(If (U={1,2,3,4,5,6,7,8,9,10,11,12}) and (A={x:x\in U,x\) divides 12}), what is (A')?

Explanation opens after your attempt
Correct Answer

A. (A'={5,7,8,9,10,11})

Step 1

Concept

(A) contains the divisors (1,2,3,4,6,12) of (12), so the remaining elements are in (A'). First form (A) from the condition.

Step 2

Why this answer is correct

The correct answer is A. (A'={5,7,8,9,10,11}). (A) contains the divisors (1,2,3,4,6,12) of (12), so the remaining elements are in (A'). First form (A) from the condition.

Step 3

Exam Tip

(A) में (12) के भाजक (1,2,3,4,6,12) हैं, इसलिए बाकी अवयव (A') में आते हैं। पहले शर्त से (A) बनाएं।
