किस असमता का हल सभी वास्तविक संख्याएं हैं?
Which inequality has all real numbers as its solution?
Explanation opens after your attempt
B. \(5x-4\leq 5x+2\)
Concept
From \(5x-4\leq 5x+2\), we get \(-4\leq 2\), which is always true. If a true constant statement remains, all real numbers are solutions.
Why this answer is correct
The correct answer is B. \(5x-4\leq 5x+2\). From \(5x-4\leq 5x+2\), we get \(-4\leq 2\), which is always true. If a true constant statement remains, all real numbers are solutions.
Exam Tip
\(5x-4\leq 5x+2\) से \(-4\leq 2\) मिलता है जो हमेशा सत्य है। सत्य स्थिर कथन आने पर सभी वास्तविक संख्याएं हल होती हैं।
