समीकरणों (kx+12y=36) और (15x+20y=60) के अनंत हल होने के लिए (k) क्या होगा?
What will (k) be for the equations (kx+12y=36) and (15x+20y=60) to have infinitely many solutions?
Explanation opens after your attempt
C. (9)
Concept
For infinitely many solutions, (k/15=12/20=36/60) must hold. Therefore, (k=9) is correct.
Why this answer is correct
The correct answer is C. (9). For infinitely many solutions, (k/15=12/20=36/60) must hold. Therefore, (k=9) is correct.
Exam Tip
अनंत हल के लिए (k/15=12/20=36/60) होना चाहिए। इसलिए (k=9) सही है।
