किस मान पर ((2m-5)x+10) का शून्यक (4) होगा?
For which value will the zero of ((2m-5)x+10) be (4)?
Explanation opens after your attempt
B. \(m=\frac{5}{4}\)
Concept
If the zero is (4), then (4(2m-5)+10=0). This gives \(m=\frac{5}{4}\).
Why this answer is correct
The correct answer is B. \(m=\frac{5}{4}\). If the zero is (4), then (4(2m-5)+10=0). This gives \(m=\frac{5}{4}\).
Exam Tip
शून्यक (4) होने पर (4(2m-5)+10=0) होगा। इससे \(m=\frac{5}{4}\) मिलता है।
