समीकरणों (11x+qy=44) और (22x+18y=88) के अनंत हल होने के लिए (q) का मान क्या है?

What is the value of (q) for the equations (11x+qy=44) and (22x+18y=88) to have infinitely many solutions?

Explanation opens after your attempt
Correct Answer

C. (9)

Step 1

Concept

The second equation is (2) times the first so (q/18=1/2) must hold. Hence, (q=9).

Step 2

Why this answer is correct

The correct answer is C. (9). The second equation is (2) times the first so (q/18=1/2) must hold. Hence, (q=9).

Step 3

Exam Tip

दूसरा समीकरण पहले का (2) गुना है इसलिए (q/18=1/2) होना चाहिए। अतः (q=9)।
