समीकरण (4x+ky=16) और (x+3y=4) के अनंत हल होने के लिए (k) क्या होगा?
What will (k) be for (4x+ky=16) and (x+3y=4) to have infinitely many solutions?
Explanation opens after your attempt
C. (12)
Concept
The first equation must be (4) times the second, so (k=12). A common multiplier makes the lines coincident.
Why this answer is correct
The correct answer is C. (12). The first equation must be (4) times the second, so (k=12). A common multiplier makes the lines coincident.
Exam Tip
पहला समीकरण दूसरे का (4) गुना होना चाहिए, इसलिए (k=12)। समान गुणक से रेखाएं संपाती बनती हैं।
