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
Correct Answer

D. (32)

Step 1

Concept

The second equation must be (2) times the first. Therefore, (n=32).

Step 2

Why this answer is correct

The correct answer is D. (32). The second equation must be (2) times the first. Therefore, (n=32).

Step 3

Exam Tip

दूसरा समीकरण पहले का (2) गुना होना चाहिए। इसलिए (n=32) होगा।
