समीकरणों (10x+3y=44) और (20x+ay=88) के अनंत हल होने के लिए (a) का मान क्या होगा?
What is the value of (a) for the equations (10x+3y=44) and (20x+ay=88) to have infinitely many solutions?
Explanation opens after your attempt
D. (6)
Concept
For infinitely many solutions, (10/20=3/a=44/88) must hold. Therefore, (a=6) is correct.
Why this answer is correct
The correct answer is D. (6). For infinitely many solutions, (10/20=3/a=44/88) must hold. Therefore, (a=6) is correct.
Exam Tip
अनंत हल के लिए (10/20=3/a=44/88) होना चाहिए। इसलिए (a=6) सही है।
