If (11x+7y=59) and (33x+21y=n) have infinitely many solutions, what is (n)?
C. (177)
दूसरा समीकरण पहले का (3) गुना होना चाहिए। इसलिए (n=177) होगा। / The second equation must be (3) times the first. Therefore, (n=177).

If (16x-8y=64) and (2x-y=t) are inconsistent, what is the correct condition for (t)?
B. \(t\ne8\)
पहले दो अनुपात बराबर हैं। असंगत होने के लिए (64/t) अलग होना चाहिए इसलिए \(t\ne8\)। / The first two ratios are equal. For inconsistency, (64/t) must be different so \(t\ne8\).

What is the most suitable conclusion by observing the equations (8x+15y=73) and (24x+45y=219)?
C. अनंत हल हैंThere are infinitely many solutions
दूसरा समीकरण पहले का (3) गुना है। इसलिए दोनों रेखाएं संपाती हैं। / The second equation is (3) times the first. Therefore, both lines are coincident.

Which conclusion is correct by observing the equations (24x+32y=96) and (3x+4y=13)?
B. पहले दो अनुपात बराबर हैं लेकिन स्थिर पद का अनुपात अलग हैFirst two ratios are equal but the constant ratio is different
यहां (24/3=32/4) लेकिन (96/13) अलग है। इसलिए कोई हल नहीं होगा। / Here (24/3=32/4) but (96/13) is different. Therefore, there will be no solution.

What is found by comparing the ratios of (a) and (b) in the equations (19x+12y=71) and (9x+6y=35)?
C. (199 \ne 12 / 6), इसलिए एक अद्वितीय हल / 6), so one unique solution
यहां पहले दो अनुपात अलग हैं। इसलिए रेखाएं एक बिंदु पर कटती हैं और एक हल देती हैं। / Here the first two ratios are different. Therefore, the lines intersect at one point and give one solution.

What type of pair is formed by the equations (30x+45y=210) and (2x+3y=14)?
A. संगत और आश्रितConsistent and dependent
पहला समीकरण दूसरे का (15) गुना है। इसलिए दोनों एक ही रेखा हैं और युग्म आश्रित है। / The first equation is (15) times the second. Therefore, both are the same line and the pair is dependent.

What type of pair is formed by the equations (26x+39y=117) and (2x+3y=10)?
C. असंगतInconsistent
यहां (26/2=39/3) लेकिन (117/10) अलग है। इसलिए यह असंगत युग्म है। / Here (26/2=39/3) but (117/10) is different. Therefore, this is an inconsistent pair.

What type of pair is formed by the equations (18x+7y=61) and (9x+4y=32)?
C. संगत और स्वतंत्रConsistent and independent
यहां \(18/9 \ne 7/4\), इसलिए रेखाएं कटती हैं। अतः युग्म संगत और स्वतंत्र है। / Here \(18/9 \ne 7/4\), so the lines intersect. Hence, the pair is consistent and independent.

C. अनंत हलInfinitely many solutions
दूसरा समीकरण पहले का (3) गुना है। इसलिए दोनों शर्तें एक ही जानकारी देती हैं और अनंत हल होते हैं। / The second equation is (3) times the first. Therefore, both conditions give the same information and have infinitely many solutions.
