C. (7)
अनंत हल के लिए (4/12=a/21=32/96) होना चाहिए। इसलिए (a=7) सही है। / For infinitely many solutions, (4/12=a/21=32/96) must hold. Therefore, (a=7) is correct.

What is the value of (p) for the equations (px+9y=45) and (20x+30y=103) to have no solution?
B. (6)
कोई हल नहीं के लिए (p/20=9/30) और (45/103) अलग होना चाहिए। इससे (p=6) मिलता है। / For no solution, (p/20=9/30) and (45/103) must be different. This gives (p=6).

If (5x+8y=37) and (15x+24y=m) form an inconsistent pair, what is the correct condition for (m)?
B. \(m\ne111\)
पहले दो अनुपात बराबर हैं। असंगत होने के लिए स्थिर पद का अनुपात अलग होना चाहिए। / The first two ratios are equal. For inconsistency, the constant ratio must be different.

Which conclusion is correct for the equations (7x-4y=29) and (21x-12y=87)?
C. अनंत हलInfinitely many solutions
दूसरा समीकरण पहले का (3) गुना है। इसलिए दोनों रेखाएं संपाती हैं और अनंत हल हैं। / The second equation is (3) times the first. Therefore, both lines are coincident and have infinitely many solutions.

How many solutions will the equations (9x+5y=41) and (18x+10y=85) have?
C. कोई हल नहींNo solution
यहां (9/18=5/10) लेकिन (41/85) अलग है। इसलिए रेखाएं समानांतर और अलग हैं। / Here (9/18=5/10) but (41/85) is different. Therefore, the lines are parallel and distinct.

What is the correct solution status for the equations (11x+14y=53) and (17x+22y=83)?
B. एक अद्वितीय हलOne unique solution
यहां \(11/17 \ne 14/22\), इसलिए रेखाएं एक बिंदु पर कटती हैं। पहले दो अनुपात अलग हों तो एक अद्वितीय हल मिलता है। / Here \(11/17 \ne 14/22\), so the lines intersect at one point. If the first two ratios are different, one unique solution is obtained.

What will (k) be for the equations (kx+14y=42) and (18x+21y=63) to have infinitely many solutions?
C. (12)
अनंत हल के लिए (k/18=14/21=42/63) होना चाहिए। इसलिए (k=12) सही है। / For infinitely many solutions, (k/18=14/21=42/63) must hold. Therefore, (k=12) is correct.

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

Which condition is correct for the equations (12x+py=60) and (3x+5y=16) to have a unique solution?
B. \(p\ne20\)
अद्वितीय हल के लिए \(12/3 \ne p/5\) होना चाहिए। इसलिए \(p\ne20\) सही शर्त है। / For a unique solution, \(12/3 \ne p/5\) must hold. Therefore, \(p\ne20\) is the correct condition.

What will (a) be for the equations (8x+ay=72) and (24x+30y=216) to have infinitely many solutions?
C. (10)
अनंत हल के लिए (8/24=a/30=72/216) होना चाहिए। इससे (a=10) मिलता है। / For infinitely many solutions, (8/24=a/30=72/216) must hold. This gives (a=10).
