समीकरण (4x+my=20) और (2x+5y=10) के अनंत हल होने के लिए (m) का मान क्या है?
What is the value of (m) for (4x+my=20) and (2x+5y=10) to have infinitely many solutions?
Explanation opens after your attempt
C. (10)
Concept
The first equation must be (2) times the second so (m=10). A common multiplier makes both lines coincident.
Why this answer is correct
The correct answer is C. (10). The first equation must be (2) times the second so (m=10). A common multiplier makes both lines coincident.
Exam Tip
पहला समीकरण दूसरे का (2) गुना होना चाहिए इसलिए (m=10)। समान गुणक से दोनों रेखाएं संपाती हो जाती हैं।
