यदि (k>0) और \(a\leq b\) है तो कौन सा निष्कर्ष सही है?

If (k>0) and \(a\leq b\), which conclusion is correct?

Explanation opens after your attempt
Correct Answer

B. \(ka\leq kb\)

Step 1

Concept

Multiplying by positive (k) keeps the direction of the inequality unchanged. Therefore \(ka\leq kb\) is correct.

Step 2

Why this answer is correct

The correct answer is B. \(ka\leq kb\). Multiplying by positive (k) keeps the direction of the inequality unchanged. Therefore \(ka\leq kb\) is correct.

Step 3

Exam Tip

धनात्मक (k) से गुणा करने पर असमता की दिशा वही रहती है। इसलिए \(ka\leq kb\) सही है।
