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
A. (-3p>-3q)
Concept
Multiplying by a negative number reverses the inequality sign. Hence (<) changes to (>).
Why this answer is correct
The correct answer is A. (-3p>-3q). Multiplying by a negative number reverses the inequality sign. Hence (<) changes to (>).
Exam Tip
ऋणात्मक संख्या से गुणा करने पर असमानता का चिन्ह उलट जाता है। इसलिए (<) बदलकर (>) होगा।
