समीकरण (5x+ky=25) और (x+3y=5) के अनंत हल होने के लिए (k) क्या होगा?

What will (k) be for (5x+ky=25) and (x+3y=5) to have infinitely many solutions?

Explanation opens after your attempt
Correct Answer

B. (15)

Step 1

Concept

The first equation must be (5) times the second. Therefore, (k=15).

Step 2

Why this answer is correct

The correct answer is B. (15). The first equation must be (5) times the second. Therefore, (k=15).

Step 3

Exam Tip

पहला समीकरण दूसरे का (5) गुना होना चाहिए। इसलिए (k=15)।
