असमानता \(x-y\geq 0\) को (y) के रूप में लिखने पर कौन सा रूप सही है?
Which form is correct when \(x-y\geq 0\) is written in terms of (y)?
Explanation opens after your attempt
Correct Answer
B. \(y\leq x\)
Concept
From \(x-y\geq 0\), \(-y\geq -x\), so \(y\leq x\). Change the inequality sign when multiplying or dividing by (-1) in exams.
Why this answer is correct
The correct answer is B. \(y\leq x\). From \(x-y\geq 0\), \(-y\geq -x\), so \(y\leq x\). Change the inequality sign when multiplying or dividing by (-1) in exams.
Exam Tip
\(x-y\geq 0\) से \(-y\geq -x\), इसलिए \(y\leq x\) मिलता है। परीक्षा में (-1) से गुणा या भाग करते समय संकेत बदलें।
