समीकरणों (3x+by=24) और (12x+20y=96) के अनंत हल होने के लिए (b) का मान क्या है?

What is the value of (b) for the equations (3x+by=24) and (12x+20y=96) to have infinitely many solutions?

Explanation opens after your attempt
Correct Answer

C. (5)

Step 1

Concept

For infinitely many solutions, (3/12=b/20=24/96) must hold. Therefore, (b=5).

Step 2

Why this answer is correct

The correct answer is C. (5). For infinitely many solutions, (3/12=b/20=24/96) must hold. Therefore, (b=5).

Step 3

Exam Tip

अनंत हल के लिए (3/12=b/20=24/96) होना चाहिए। इसलिए (b=5)।
