समीकरणों (3x+ky=12) और (9x+15y=36) के अनंत हल होने के लिए (k) का मान क्या होगा?

What is the value of (k) for the equations (3x+ky=12) and (9x+15y=36) to have infinitely many solutions?

Explanation opens after your attempt
Correct Answer

C. (5)

Step 1

Concept

For infinitely many solutions, (3/9=k/15=12/36) must hold. Therefore, (k=5) is correct.

Step 2

Why this answer is correct

The correct answer is C. (5). For infinitely many solutions, (3/9=k/15=12/36) must hold. Therefore, (k=5) is correct.

Step 3

Exam Tip

अनंत हल के लिए (3/9=k/15=12/36) होना चाहिए। इसलिए (k=5) सही है।
