यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\) और \(A=\{1,4,9\}\) है, तो (A') में कितने तत्व होंगे?

If \(U=\{1,2,3,4,5,6,7,8,9,10\}\) and \(A=\{1,4,9\}\), how many elements will (A') have?

Explanation opens after your attempt
Correct Answer

C. (7)

Step 1

Concept

(U) has (10) elements and (A) has (3) elements. Hence (n(A')=10-3=7).

Step 2

Why this answer is correct

The correct answer is C. (7). (U) has (10) elements and (A) has (3) elements. Hence (n(A')=10-3=7).

Step 3

Exam Tip

(U) में (10) और (A) में (3) तत्व हैं। अतः (n(A')=10-3=7)।
