समीकरणों (5x+9y=64) और (15x+27y=t) के असंगत होने के लिए (t) के लिए सही शर्त क्या है?

What is the correct condition on (t) for the equations (5x+9y=64) and (15x+27y=t) to be inconsistent?

Explanation opens after your attempt
Correct Answer

B. \(t\ne192\)

Step 1

Concept

The first two ratios are equal. For inconsistency, the constant ratio must be different so \(t\ne192\).

Step 2

Why this answer is correct

The correct answer is B. \(t\ne192\). The first two ratios are equal. For inconsistency, the constant ratio must be different so \(t\ne192\).

Step 3

Exam Tip

पहले दो अनुपात बराबर हैं। असंगत होने के लिए स्थिर पद का अनुपात अलग होना चाहिए इसलिए \(t\ne192\)।

नीचे में से कौन-सा युग्म असंगत है?

Which of the following pairs is inconsistent?

Explanation opens after your attempt
Correct Answer

A. (x+4y=6) और (2x+8y=13)(x+4y=6) and (2x+8y=13)

Step 1

Concept

In the first option (1/2=4/8) but (6/13) is different. Therefore the lines are distinct parallel.

Step 2

Why this answer is correct

The correct answer is A. (x+4y=6) और (2x+8y=13) / (x+4y=6) and (2x+8y=13). In the first option (1/2=4/8) but (6/13) is different. Therefore the lines are distinct parallel.

फ्रांसीसी क्रांति में राष्ट्रवादी उपायों में असंगत विकल्प कौन सा है?

Which option is inconsistent among the nationalist measures of the French Revolution?

Explanation opens after your attempt
Correct Answer

C. राजा के जन्मजात विशेषाधिकार मजबूत करनाStrengthening the king's birth-based privileges

Step 1

Concept

Revolutionary measures were linked with equality and the civic nation.

Step 2

Why this answer is correct

Common language, uniform laws and centralised administration were nation-building measures.

Step 3

Exam Tip

Strengthening birth-based privilege is opposite to the Revolution. चरण 1: क्रांतिकारी उपाय समानता और नागरिक राष्ट्र से जुड़े थे। चरण 2: साझा भाषा, समान कानून और केंद्रीकृत प्रशासन राष्ट्र निर्माण के उपाय थे। चरण 3: जन्मजात विशेषाधिकार मजबूत करना क्रांति के विपरीत है।

Step 1

Concept

Revolutionary measures aimed to weaken the king-centred order.

Why this answer is correct

The tricolour, uniform laws and common language were nationalist measures.

Step 3

Exam Tip

Strengthening hereditary privileges is opposite to revolutionary ideas. चरण 1: क्रांतिकारी उपायों का लक्ष्य राजा-केंद्रित व्यवस्था को कमजोर करना था। चरण 2: तिरंगा, समान कानून और साझा भाषा राष्ट्रवादी उपाय थे। चरण 3: वंशानुगत विशेषाधिकार बढ़ाना क्रांतिकारी विचार के विपरीत है।

If (4,x,2x+1,25) are consecutive terms of an arithmetic progression, what is the correct conclusion about (x)?

Explanation opens after your attempt
Correct Answer

D. कोई मान संभव नहींNo value is possible

Step 1

Concept

(25-4=21) is split into three equal gaps, so the second term should be (11) and the third (18). This makes (x=11) and (2x+1=18) impossible together.

Step 2

Why this answer is correct

The correct answer is D. कोई मान संभव नहीं / No value is possible. (25-4=21) is split into three equal gaps, so the second term should be (11) and the third (18). This makes (x=11) and (2x+1=18) impossible together.

Step 3

Exam Tip

(25-4=21) तीन बराबर अंतरालों में बंटेगा इसलिए दूसरा पद (11) और तीसरा (18) होना चाहिए। इससे (x=11) और (2x+1=18) साथ-साथ सत्य नहीं होते।

If (2,x+3,3x+1,20) are consecutive terms of an arithmetic progression, what will (x) be?

Explanation opens after your attempt
Correct Answer

D. कोई मान नहींNo value

Step 1

Concept

(20-2=18) is split into three gaps, so the second term should be (8) and the third (14). This gives (x=5) and \(x=\frac{13}{3}\), so no single value is possible.

Step 2

Why this answer is correct

The correct answer is D. कोई मान नहीं / No value. (20-2=18) is split into three gaps, so the second term should be (8) and the third (14). This gives (x=5) and \(x=\frac{13}{3}\), so no single value is possible.

Step 3

Exam Tip

(20-2=18) तीन अंतरालों में बंटता है, इसलिए दूसरा पद (8) और तीसरा (14) होना चाहिए। इससे (x=5) और \(x=\frac{13}{3}\) मिलते हैं, इसलिए कोई एक मान संभव नहीं है।

If (4, x+2, 2x+1, 19) are in an arithmetic progression, what should be the value of (x)?

Explanation opens after your attempt
Correct Answer

D. कोई मान नहींNo value

Step 1

Concept

The total difference from (4) to (19) is (15), so (d=5), the second term should be (9) and the third (14); this gives (x=7) and \(x=\frac{13}{2}\). Therefore no single (x) is possible.

Step 2

Why this answer is correct

The correct answer is D. कोई मान नहीं / No value. The total difference from (4) to (19) is (15), so (d=5), the second term should be (9) and the third (14); this gives (x=7) and \(x=\frac{13}{2}\). Therefore no single (x) is possible.

Step 3

Exam Tip

(4) से (19) तक कुल अंतर (15) है, इसलिए (d=5), दूसरा पद (9) और तीसरा (14) होना चाहिए; इससे (x=7) और \(x=\frac{13}{2}\) दोनों मिलते हैं। इसलिए कोई एक (x) संभव नहीं है।

C. (n=5)

Step 1

Concept

Equating coefficient ratios, \(\frac{2}{6}=\frac{n}{15}\) gives (n=5). The constant ratio is different, so the pair is inconsistent.

The correct answer is C. असंगत / Inconsistent. Here (26/2=39/3) but (117/10) is different. Therefore, this is an inconsistent pair.

Step 3

Exam Tip

यहां (26/2=39/3) लेकिन (117/10) अलग है। इसलिए यह असंगत युग्म है।

What type of pair is formed by the equations (30x+45y=210) and (2x+3y=14)?

Explanation opens after your attempt
Correct Answer

A. संगत और आश्रितConsistent and dependent

Step 1

Concept

The first equation is (15) times the second. Therefore, both are the same line and the pair is dependent.

Step 2

Why this answer is correct

The correct answer is A. संगत और आश्रित / Consistent and dependent. The first equation is (15) times the second. Therefore, both are the same line and the pair is dependent.

Step 3

Exam Tip

पहला समीकरण दूसरे का (15) गुना है। इसलिए दोनों एक ही रेखा हैं और युग्म आश्रित है।

दो वस्तुओं की कीमतों के लिए (9x+4y=360) और (27x+12y=1090) समीकरण बने। यह प्रणाली कैसी है?

For prices of two items, the equations (9x+4y=360) and (27x+12y=1090) are formed. What type of system is this?

Explanation opens after your attempt
Correct Answer

C. असंगतInconsistent

Step 1

Concept

The first two ratios are equal but (360/1090) is different. Therefore, the system is inconsistent.

Step 2

Why this answer is correct

The correct answer is C. असंगत / Inconsistent. The first two ratios are equal but (360/1090) is different. Therefore, the system is inconsistent.

Step 3
