यदि \(U={1,2,\ldots,24}\), (A'={1,5,7,11,13,17,19,23}), तो (A) में कितने अवयव हैं?

If \(U={1,2,\ldots,24}\), (A'={1,5,7,11,13,17,19,23}), how many elements are in (A)?

Explanation opens after your attempt
Correct Answer

C. (16)

Step 1

Concept

(|U|=24) and (|A'|=8), so (|A|=24-8=16). The count of a set is found by subtracting its complement from the total.

Step 2

Why this answer is correct

The correct answer is C. (16). (|U|=24) and (|A'|=8), so (|A|=24-8=16). The count of a set is found by subtracting its complement from the total.

Step 3

Exam Tip

(|U|=24) और (|A'|=8), इसलिए (|A|=24-8=16)। पूरक की संख्या कुल में से घटाकर मिलती है।
