\(यदि (U={x:x\in\mathbb{N},1\le x\le 50}) और (A={x:x\) 5 से विभाज्य है\(}) है, तो (n(A^c)) कितना होगा\)?

\(If (U={x:x\in\mathbb{N},1\le x\le 50}) and (A={x:x\) is divisible by \(5}), what is (n(A^c))\)?

Explanation opens after your attempt
Correct Answer

A. (40)

Step 1

Concept

There are (10) multiples of (5) from (1) to (50). Therefore (n\(A^c\)=50-10=40).

Step 2

Why this answer is correct

The correct answer is A. (40). There are (10) multiples of (5) from (1) to (50). Therefore (n\(A^c\)=50-10=40).

Step 3

Exam Tip

(1) से (50) तक (5) के (10) गुणज हैं। इसलिए (n\(A^c\)=50-10=40) होगा।
