यदि (8x+5y=43) और (24x+15y=n) के अनंत हल हैं, तो (n) कितना होगा?
If (8x+5y=43) and (24x+15y=n) have infinitely many solutions, what is (n)?
Explanation opens after your attempt
C. (129)
Concept
The second equation must be (3) times the first. Therefore, (n=129).
Why this answer is correct
The correct answer is C. (129). The second equation must be (3) times the first. Therefore, (n=129).
Exam Tip
दूसरा समीकरण पहले का (3) गुना होना चाहिए। इसलिए (n=129) होगा।
