समीकरणों (px+6y=18) और (10x+15y=45) के अनंत हल होने के लिए (p) क्या होगा?
What will (p) be for the equations (px+6y=18) and (10x+15y=45) to have infinitely many solutions?
Explanation opens after your attempt
B. (3)
Concept
For infinitely many solutions, (p/10=6/15=18/45) must hold. Since the common ratio is (2/5), (p=4) would be required.
Why this answer is correct
The correct answer is B. (3). For infinitely many solutions, (p/10=6/15=18/45) must hold. Since the common ratio is (2/5), (p=4) would be required.
Exam Tip
अनंत हल के लिए (p/10=6/15=18/45) होना चाहिए। इसलिए (p=4) नहीं, (p=4) नहीं बल्कि (p=4) अनुपात बिगाड़ता है और सही (p=4) नहीं है।
