Which relation is correct for (8x+12y=40) and (2x+3y=12)?
C. (82=12 / 3 \ne 40 / 12)
पहले दो अनुपात बराबर हैं लेकिन स्थिर पद का अनुपात अलग है। इसलिए कोई हल नहीं है। / The first two ratios are equal but the constant ratio is different. Therefore, there is no solution.

Which statement is correct for (6x+7y=23) and (12x+13y=45)?
B. (612 \ne 7 / 13), इसलिए एक अद्वितीय हल / 13), so one unique solution
यहां \(6/12 \ne 7/13\), इसलिए रेखाएं कटती हैं। इस कारण एक अद्वितीय हल है। / Here \(6/12 \ne 7/13\), so the lines intersect. Therefore, there is one unique solution.

What should (s) be for (2x+5y=17) and (4x+10y=s) to be consistent and dependent?
C. (34)
संगत और आश्रित होने के लिए दूसरा समीकरण पहले का (2) गुना होना चाहिए। अतः (s=34)। / To be consistent and dependent, the second equation must be (2) times the first. Hence, (s=34).

Which condition is correct for (5x+6y=29) and (10x+12y=r) to be inconsistent?
B. \(r \ne 58\)
पहले दो अनुपात बराबर हैं, इसलिए असंगत होने के लिए स्थिर पद का अनुपात अलग होना चाहिए। अतः \(r \ne 58\)। / The first two ratios are equal, so for inconsistency the constant ratio must be different. Hence, \(r \ne 58\).

What will (a) be for (3x+4y=10) and (6x+ay=25) to have no solution?
C. (8)
कोई हल नहीं के लिए (3/6=4/a) और (10/25) अलग होना चाहिए। इससे (a=8) मिलता है। / For no solution, (3/6=4/a) and (10/25) must be different. This gives (a=8).

What will (k) be for (6x+ky=42) and (2x+5y=14) to have infinitely many solutions?
B. (15)
पहला समीकरण दूसरे का (3) गुना होना चाहिए। इसलिए (k=15) है। / The first equation must be (3) times the second. Therefore, (k=15).

If (lx+9y=27) and (8x+18y=55) have no solution, what will be the value of (l)?
C. (4)
कोई हल नहीं के लिए (l/8=9/18) और (27/55) अलग होना चाहिए। इसलिए (l=4)। / For no solution, (l/8=9/18) and (27/55) must be different. Hence, (l=4).

Which statement is correct by observing (9x+2y=31) and (18x+4y=62)?
B. रेखाएं एक ही हैंLines are the same
दूसरा समीकरण पहले का (2) गुना है। इसलिए दोनों रेखाएं एक ही हैं। / The second equation is (2) times the first. Therefore, both lines are the same.

What is the correct conclusion by observing (12x-8y=20) and (3x-2y=6)?
A. कोई हल नहींNo solution
यहां (12/3=(-8)/(-2)) लेकिन (20/6) अलग है। इसलिए रेखाएं समानांतर और अलग हैं। / Here (12/3=(-8)/(-2)) but (20/6) is different. Therefore, the lines are parallel and distinct.

What is the correct solution status for (15x+4y=37) and (7x+2y=18)?
C. एक अद्वितीय हलOne unique solution
यहां \(15/7 \ne 4/2\), इसलिए रेखाएं कटेंगी। अतः एक अद्वितीय हल है। / Here \(15/7 \ne 4/2\), so the lines will intersect. Hence, there is one unique solution.
