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
C. (9)
Concept
The second equation is (2) times the first so (q/18=1/2) must hold. Hence, (q=9).
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).
Exam Tip
दूसरा समीकरण पहले का (2) गुना है इसलिए (q/18=1/2) होना चाहिए। अतः (q=9)।
