समीकरणों (13x+8y=49) और (26x+16y=r) के असंगत होने के लिए कौन-सी शर्त सही है?

Which condition is correct for the equations (13x+8y=49) and (26x+16y=r) to be inconsistent?

Explanation opens after your attempt
Correct Answer

B. \(r\ne98\)

Step 1

Concept

The first two ratios are equal. For inconsistency, the constant ratio must be different so \(r\ne98\).

Step 2

Why this answer is correct

The correct answer is B. \(r\ne98\). The first two ratios are equal. For inconsistency, the constant ratio must be different so \(r\ne98\).

Step 3

Exam Tip

पहले दो अनुपात बराबर हैं। असंगत होने के लिए स्थिर पद का अनुपात अलग होना चाहिए इसलिए \(r\ne98\)।

Explanation opens after your attempt
Correct Answer

A. (5x+2y=9) और (10x+4y=25)(5x+2y=9) and (10x+4y=25)

Step 1

Multiplying the first equation by (2) gives (2x-6y=10), different from the second. Hence the lines are parallel and have no solution.

Step 2

Why this answer is correct

The correct answer is B. समांतर और कोई हल नहीं / Parallel with no solution. Multiplying the first equation by (2) gives (2x-6y=10), different from the second. Hence the lines are parallel and have no solution.

Step 3

Exam Tip

पहले समीकरण को (2) से गुणा करने पर (2x-6y=10), जो दूसरे से अलग है। इसलिए रेखाएँ समांतर हैं और कोई हल नहीं है।

यदि \(a_1=1,\ b_1=2,\ c_1=5\) और \(a_2=2,\ b_2=4,\ c_2=7\), तो सही निष्कर्ष क्या है?

If \(a_1=1,\ b_1=2,\ c_1=5\) and \(a_2=2,\ b_2=4,\ c_2=7\), what is the correct conclusion?

Correct Answer

C. रेखाएँ समांतर हैंLines are parallel

Step 1

Concept

\(\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{1}{2}\), but \(\frac{c_1}{c_2}=\frac{5}{7}\). Hence the lines are parallel and inconsistent.

Step 2

Why this answer is correct

The correct answer is C. रेखाएँ समांतर हैं / Lines are parallel. \(\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{1}{2}\), but \(\frac{c_1}{c_2}=\frac{5}{7}\). Hence the lines are parallel and inconsistent.

Step 3

Exam Tip

\(\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{1}{2}\), लेकिन \(\frac{c_1}{c_2}=\frac{5}{7}\)। इसलिए रेखाएँ समांतर और असंगत हैं।

Correct Answer

C. समांतर होंगीThey will be parallel

Step 1

Concept

This condition represents distinct parallel lines. In exams, write such a pair as inconsistent.

Step 2

Why this answer is correct

The correct answer is C. समांतर होंगी / They will be parallel. This condition represents distinct parallel lines. In exams, write such a pair as inconsistent.

Step 3

Exam Tip

यह स्थिति अलग-अलग समांतर रेखाओं की होती है। परीक्षा में ऐसे युग्म को असंगत लिखें।
