यदि \( kx-3\leq 9 \) का हल \(x\leq 4\) है और (k>0), तो (k) क्या है?
If the solution of \( kx-3\leq 9 \) is \(x\leq 4\) and (k>0), what is (k)?
Explanation opens after your attempt
Correct Answer
B. (3)
Concept
The solution is \(x\leq \frac{12}{k}\). Matching it with \(x\leq 4\) gives (k=3).
Why this answer is correct
The correct answer is B. (3). The solution is \(x\leq \frac{12}{k}\). Matching it with \(x\leq 4\) gives (k=3).
Exam Tip
हल \(x\leq \frac{12}{k}\) होगा। इसे \(x\leq 4\) से मिलाने पर (k=3) मिलता है।
