समीकरणों (3x+ky=12) और (9x+15y=36) के अनंत हल होने के लिए (k) का मान क्या होगा?
What is the value of (k) for the equations (3x+ky=12) and (9x+15y=36) to have infinitely many solutions?
Explanation opens after your attempt
C. (5)
Concept
For infinitely many solutions, (3/9=k/15=12/36) must hold. Therefore, (k=5) is correct.
Why this answer is correct
The correct answer is C. (5). For infinitely many solutions, (3/9=k/15=12/36) must hold. Therefore, (k=5) is correct.
Exam Tip
अनंत हल के लिए (3/9=k/15=12/36) होना चाहिए। इसलिए (k=5) सही है।
