What is the value of (b) for the equations (bx+16y=64) and (14x+28y=131) to have no solution?
C. (8)
कोई हल नहीं के लिए (b/14=16/28) और (64/131) अलग होना चाहिए। इसलिए (b=8)। / For no solution, (b/14=16/28) and (64/131) must be different. Hence, (b=8).

Which statement is correct about the graph of the equations (22x+33y=99) and (2x+3y=12)?
C. रेखाएं अलग समानांतर हैंLines are distinct parallel
यहां (22/2=33/3) लेकिन (99/12) अलग है। इसलिए ग्राफ में अलग समानांतर रेखाएं बनेंगी। / Here (22/2=33/3) but (99/12) is different. Therefore, the graph will show distinct parallel lines.

What will be shown in the graph of the equations (30x+18y=126) and (5x+3y=21)?
A. एक ही रेखाSame line
पहला समीकरण दूसरे का (6) गुना है। इसलिए दोनों समीकरण एक ही रेखा दिखाते हैं। / The first equation is (6) times the second. Therefore, both equations show the same line.

What is the correct description of the graph of the equations (5x+17y=69) and (12x+41y=166)?
C. एक बिंदु पर कटती रेखाएंLines intersecting at one point
यहां \(5/12 \ne 17/41\), इसलिए रेखाएं एक बिंदु पर कटेंगी। इससे एक अद्वितीय हल मिलेगा। / Here \(5/12 \ne 17/41\), so the lines will intersect at one point. This gives one unique solution.

Which ratio relation is correct for the equations (10x+13y-71=0) and (30x+39y-213=0)?
C. (1030=13 / 39=(-71) / (-213))
यहां तीनों अनुपात बराबर हैं। इसलिए दोनों रेखाएं संपाती हैं और अनंत हल हैं। / Here all three ratios are equal. Therefore, both lines are coincident and have infinitely many solutions.

What is the correct ratio relation for the equations (16x-9y+55=0) and (32x-18y+113=0)?
A. (1632=(-9) / (-18) \ne 55 / 113)
पहले दो अनुपात बराबर हैं और तीसरा अलग है। इसलिए कोई हल नहीं होगा। / The first two ratios are equal and the third is different. Therefore, there will be no solution.

What is the correct conclusion for the equations (15x+8y-47=0) and (30x+17y-94=0)?
C. एक अद्वितीय हलOne unique solution
यहां \(15/30 \ne 8/17\), इसलिए रेखाएं एक बिंदु पर कटती हैं। ऐसी स्थिति में एक अद्वितीय हल मिलता है। / Here \(15/30 \ne 8/17\), so the lines intersect at one point. In this case, one unique solution is obtained.

If (cx+18y=72) and (24x+48y=145) have no solution, what will (c) be?
C. (9)
कोई हल नहीं के लिए (c/24=18/48) और (72/145) अलग होना चाहिए। इसलिए (c=9)। / For no solution, (c/24=18/48) and (72/145) must be different. Therefore, (c=9).

C. (9)
अनंत हल के लिए (7/28=d/36=63/252) होना चाहिए। इसलिए (d=9)। / For infinitely many solutions, (7/28=d/36=63/252) must hold. Therefore, (d=9).

Which condition is correct for the equations (17x+py=51) and (8x+3y=25) to have a unique solution?
B. (p\ne518)
अद्वितीय हल के लिए \(17/8 \ne p/3\) होना चाहिए। इसलिए \(p\ne51/8\) सही शर्त है। / For a unique solution, \(17/8 \ne p/3\) must hold. Therefore, \(p\ne51/8\) is the correct condition.
