If (m>n) and (r<0), which option is correct?यदि (m>n) और (r<0), तो कौन सा विकल्प सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (mr<nr)(mr<nr)
Multiplying by negative (r) changes (>) into (<). In exams watch for reversal in options containing (r<0).ऋणात्मक (r) से गुणा करने पर (>) चिह्न (<) में बदलता है। परीक्षा में (r<0) वाले विकल्पों में उलटाव देखें।
