यदि \(A=\{1,2,3,4,5\}\) पर \(R={(a,b):a\) is multiple of (b}), तो कौन सा ordered pair (R) में है?

If \(R={(a,b):a\) is multiple of (b}) on \(A=\{1,2,3,4,5\}\), which ordered pair belongs to (R)?

Explanation opens after your attempt
Correct Answer

B. ( (4,2) )

Step 1

Concept

(4) is a multiple of (2), so \((4,2)\in R\). In exams, understand the direction of multiple of and divides separately.

Step 2

Why this answer is correct

The correct answer is B. ( (4,2) ). (4) is a multiple of (2), so \((4,2)\in R\). In exams, understand the direction of multiple of and divides separately.

Step 3

Exam Tip

(4), (2) का multiple है, इसलिए \((4,2)\in R\)। परीक्षा में multiple of और divides की दिशा अलग समझें।
