समीकरण (5x+6y=29) और (10x+12y=r) के असंगत होने के लिए कौन-सी शर्त सही है?
Which condition is correct for (5x+6y=29) and (10x+12y=r) to be inconsistent?
Explanation opens after your attempt
B. \(r \ne 58\)
Concept
The first two ratios are equal, so for inconsistency the constant ratio must be different. Hence, \(r \ne 58\).
Why this answer is correct
The correct answer is B. \(r \ne 58\). The first two ratios are equal, so for inconsistency the constant ratio must be different. Hence, \(r \ne 58\).
Exam Tip
पहले दो अनुपात बराबर हैं, इसलिए असंगत होने के लिए स्थिर पद का अनुपात अलग होना चाहिए। अतः \(r \ne 58\)।
