किस वास्तविक (x) के लिए \(\frac{x-2}{3}+\frac{2x+1}{4}<\frac{5x-7}{6}\) है?
For which real (x) is \(\frac{x-2}{3}+\frac{2x+1}{4}<\frac{5x-7}{6}\)?
Explanation opens after your attempt
B. \(x>\frac{1}{2}\)
Concept
Multiplying by positive (12) gives (4x-8+6x+3<10x-14). This reduces to (-5<-14), which is false, so there is no solution.
Why this answer is correct
The correct answer is B. \(x>\frac{1}{2}\). Multiplying by positive (12) gives (4x-8+6x+3<10x-14). This reduces to (-5<-14), which is false, so there is no solution.
Exam Tip
धनात्मक (12) से गुणा करने पर (4x-8+6x+3<10x-14) मिलता है। इससे (-5<-14) असत्य है, इसलिए कोई हल नहीं।
