यदि दोनों पक्षों को (-3) से गुणा किया जाए, तो असमानता (p<q) क्या बनेगी?

If both sides are multiplied by (-3), what will the inequality (p<q) become?

Explanation opens after your attempt
Correct Answer

A. (-3p>-3q)

Step 1

Concept

Multiplying by a negative number reverses the inequality sign. Hence (<) changes to (>).

Step 2

Why this answer is correct

The correct answer is A. (-3p>-3q). Multiplying by a negative number reverses the inequality sign. Hence (<) changes to (>).

Step 3

Exam Tip

ऋणात्मक संख्या से गुणा करने पर असमानता का चिन्ह उलट जाता है। इसलिए (<) बदलकर (>) होगा।
