समीकरणों (11x+py=33) और (4x+2y=15) का अद्वितीय हल होने के लिए कौन-सी शर्त सही है?
Which condition is correct for the equations (11x+py=33) and (4x+2y=15) to have a unique solution?
Explanation opens after your attempt
B. (p \ne 112)
Concept
For a unique solution, \(11/4 \ne p/2\) must hold. Therefore, \(p \ne 11/2\) is the correct condition.
Why this answer is correct
The correct answer is B. \(p \ne 11 / 2\). For a unique solution, \(11/4 \ne p/2\) must hold. Therefore, \(p \ne 11/2\) is the correct condition.
Exam Tip
अद्वितीय हल के लिए \(11/4 \ne p/2\) होना चाहिए। इसलिए \(p \ne 11/2\) सही शर्त है।
