समीकरणों (mx+5y=15) और (18x+15y=45) के अनंत हल होने के लिए (m) का मान क्या होगा?
What will be the value of (m) for the equations (mx+5y=15) and (18x+15y=45) to have infinitely many solutions?
Explanation opens after your attempt
C. (6)
Concept
For infinitely many solutions, (m/18=5/15=15/45) must hold. Therefore, (m=6) is correct.
Why this answer is correct
The correct answer is C. (6). For infinitely many solutions, (m/18=5/15=15/45) must hold. Therefore, (m=6) is correct.
Exam Tip
अनंत हल के लिए (m/18=5/15=15/45) होना चाहिए। इसलिए (m=6) सही है।
