यदि \(A=\{1,2,3,4\}\) और \(R=\{(a,b):a+b\leq5\}\), तो ( (4,2) ) के बारे में क्या सही है?

If \(A=\{1,2,3,4\}\) and \(R=\{(a,b):a+b\leq5\}\), what is true about ( (4,2) )?

Explanation opens after your attempt
Correct Answer

B. \((4,2)\notin R\)

Step 1

Concept

Because (4+2=6), which is greater than (5), \((4,2)\notin R\). In exams, apply the condition directly to the ordered pair.

Step 2

Why this answer is correct

The correct answer is B. \((4,2)\notin R\). Because (4+2=6), which is greater than (5), \((4,2)\notin R\). In exams, apply the condition directly to the ordered pair.

Step 3

Exam Tip

क्योंकि (4+2=6), जो (5) से बड़ा है, इसलिए \((4,2)\notin R\)। परीक्षा में ordered pair पर शर्त सीधे लगाएं।
