यदि (12x-6y=42) और (2x-y=t) असंगत हैं, तो (t) के लिए सही शर्त क्या है?
If (12x-6y=42) and (2x-y=t) are inconsistent, what is the correct condition for (t)?
Explanation opens after your attempt
B. \(t \ne 7\)
Concept
The first two ratios are equal, so (42/t) must be different for inconsistency. Hence, \(t \ne 7\).
Why this answer is correct
The correct answer is B. \(t \ne 7\). The first two ratios are equal, so (42/t) must be different for inconsistency. Hence, \(t \ne 7\).
Exam Tip
पहले दो अनुपात बराबर हैं, इसलिए असंगत होने के लिए (42/t) अलग होना चाहिए। अतः \(t \ne 7\)।
