यदि (5x+2y=16) और (10x+4y=n) के अनंत हल हैं, तो (n) कितना होगा?
If (5x+2y=16) and (10x+4y=n) have infinitely many solutions, what is (n)?
Explanation opens after your attempt
D. (32)
Concept
The second equation must be (2) times the first. Therefore, (n=32).
Why this answer is correct
The correct answer is D. (32). The second equation must be (2) times the first. Therefore, (n=32).
Exam Tip
दूसरा समीकरण पहले का (2) गुना होना चाहिए। इसलिए (n=32) होगा।
