समीकरणों (bx+12y=48) और (10x+30y=101) का कोई हल न होने के लिए (b) का मान क्या होगा?
What is the value of (b) for the equations (bx+12y=48) and (10x+30y=101) to have no solution?
Explanation opens after your attempt
B. (4)
Concept
For no solution, (b/10=12/30) and (48/101) must be different. Hence, (b=4).
Why this answer is correct
The correct answer is B. (4). For no solution, (b/10=12/30) and (48/101) must be different. Hence, (b=4).
Exam Tip
कोई हल नहीं के लिए (b/10=12/30) और (48/101) अलग होना चाहिए। इसलिए (b=4)।
