समीकरण (px+2y=6) और (9x+6y=18) के अनंत हल होने के लिए (p) का मान क्या है?
What is the value of (p) for (px+2y=6) and (9x+6y=18) to have infinitely many solutions?
Explanation opens after your attempt
C. (3)
Concept
For infinitely many solutions, (p/9=2/6=6/18), so (p=3). All three ratios must be equal.
Why this answer is correct
The correct answer is C. (3). For infinitely many solutions, (p/9=2/6=6/18), so (p=3). All three ratios must be equal.
Exam Tip
अनंत हल के लिए (p/9=2/6=6/18), इसलिए (p=3)। तीनों अनुपात बराबर होने चाहिए।
