समीकरणों (cx+10y=50) और (9x+15y=80) का कोई हल न होने के लिए (c) का मान क्या होगा?
What is the value of (c) for the equations (cx+10y=50) and (9x+15y=80) to have no solution?
Explanation opens after your attempt
B. (6)
Concept
For no solution, (c/9=10/15) and (50/80) must be different. Therefore, (c=6).
Why this answer is correct
The correct answer is B. (6). For no solution, (c/9=10/15) and (50/80) must be different. Therefore, (c=6).
Exam Tip
कोई हल नहीं के लिए (c/9=10/15) और (50/80) अलग होना चाहिए। इसलिए (c=6) है।
