यदि \(A=\{1,2,3,4\}\) पर \(R=\{(a,b):a+b\leq5\}\), तो कौन सा ordered pair (R) में है?

If \(R=\{(a,b):a+b\leq5\}\) on \(A=\{1,2,3,4\}\), which ordered pair belongs to (R)?

Correct Answer

C. ( (2,3) )

Step 1

Concept

Since \(2+3=5\leq5\), \((2,3)\in R\). In exams, include equality in an inequality with \( \leq \).

Step 2

Why this answer is correct

The correct answer is C. ( (2,3) ). Since \(2+3=5\leq5\), \((2,3)\in R\). In exams, include equality in an inequality with \( \leq \).

Step 3

Exam Tip

क्योंकि \(2+3=5\leq5\), इसलिए \((2,3)\in R\)। परीक्षा में inequality में बराबरी को भी शामिल करें।
