यदि \(\sqrt{3}\) को परिमेय मानकर प्रमाण में विरोधाभास नहीं मिल रहा, तो कौन-सी शर्त शायद छूट गई है?

If no contradiction appears while proving \(\sqrt{3}\) irrational by assuming it rational, which condition is probably missing?

Explanation opens after your attempt
Correct Answer

A. भिन्न को सरलतम रूप में लेनाTaking the fraction in lowest form

Step 1

Concept

The contradiction works only when numerator and denominator are first assumed coprime.

Step 2

Why this answer is correct

If lowest form is missing, a common factor will not be decisive.

Step 3

Exam Tip

So write the fraction in lowest form at the start. चरण 1: विरोधाभास तभी बनेगा जब अंश और हर पहले से सहअभाज्य माने गए हों। चरण 2: सरलतम रूप छूटने पर साझा गुणनखंड मिलना निर्णायक नहीं रहेगा। चरण 3: इसलिए आरंभ में ही सरलतम भिन्न लिखें।

यदि \(\sqrt{2}\) का प्रमाण लिखते समय छात्र \(q\neq0\) नहीं लिखता, तो क्या कमी रह जाती है?

If a student does not write \(q\neq0\) while proving \(\sqrt{2}\) irrational, what is missing?

Explanation opens after your attempt
Correct Answer

A. परिमेय संख्या के रूप की आवश्यक शर्त अधूरी रह जाती हैThe necessary condition of the rational form is incomplete

Step 1

Concept

\(\frac{p}{q}\) is valid only when \(q\neq0\).

Step 2

Why this answer is correct

This condition is necessary when writing the rational form.

Step 3

Exam Tip

Small conditions make the proof complete. चरण 1: \(\frac{p}{q}\) तभी मान्य है जब \(q\neq0\) हो। चरण 2: परिमेय रूप लिखते समय यह शर्त जरूरी है। चरण 3: छोटी शर्तें भी प्रमाण को पूर्ण बनाती हैं।

Explanation opens after your attempt
Correct Answer

A. वह संस्थाओं उपाधियों चुनावों शिक्षा न्याय और कर के प्रश्नों को छोड़ देगाThe student would miss issues of institutions titles elections education justice and tax

Step 1

Concept

Boycott of foreign cloth was one part of the movement.

Step 2

Why this answer is correct

यदि (-6,s,10,18) अंकगणितीय श्रेणी के क्रमागत पद हैं तो (s) क्या होगा?

If (-6,s,10,18) are consecutive terms of an arithmetic progression, what will (s) be?

Explanation opens after your attempt
Correct Answer

B. (2)

Step 1

Concept

(18-10=8), so (s=10-8=2). While moving backward, subtract the same (d).

Step 2

Why this answer is correct

The correct answer is B. (2). (18-10=8), so (s=10-8=2). While moving backward, subtract the same (d).

Step 3

Exam Tip

(18-10=8), इसलिए (s=10-8=2)। पीछे की ओर चलते समय वही (d) घटाएं।

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 (2,x,y,20) are consecutive terms of an arithmetic progression, what is (x+y)?

Explanation opens after your attempt
Correct Answer

C. (22)

Step 1

Concept

The total difference (20-2=18) is split into three equal gaps, so (d=6). Hence (x=8), (y=14), and (x+y=22).

Step 2

Why this answer is correct

The correct answer is C. (22). The total difference (20-2=18) is split into three equal gaps, so (d=6). Hence (x=8), (y=14), and (x+y=22).

Step 3

Exam Tip

कुल अंतर (20-2=18) तीन बराबर भागों में बंटेगा, इसलिए (d=6)। अतः (x=8), (y=14) और (x+y=22)।

Explanation opens after your attempt
Correct Answer

C. (13)

Step 1

Concept

(25-19=6), so (u=19-6=13). While finding a missing term, apply the same difference backward too.

Step 2

Why this answer is correct

The correct answer is C. (13). (25-19=6), so (u=19-6=13). While finding a missing term, apply the same difference backward too.

Step 3

Exam Tip

(25-19=6), इसलिए (u=19-6=13)। खाली पद निकालते समय समान अंतर को पीछे की ओर भी लगाएं।

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

Explanation opens after your attempt
Correct Answer

C. (10)

Step 1

Concept

(25-4=21) is split into three equal gaps, so (d=7), and (x+1=11) gives (x=10). In four consecutive terms, finding (d) from first and last terms is fast.

Step 2

Why this answer is correct

The correct answer is C. (10). (25-4=21) is split into three equal gaps, so (d=7), and (x+1=11) gives (x=10). In four consecutive terms, finding (d) from first and last terms is fast.

Step 3

Exam Tip

(25-4=21) तीन समान अंतरालों में बंटता है, इसलिए (d=7) और (x+1=11) से (x=10)। चार क्रमागत पदों में पहले और अंतिम पद से (d) निकालना तेज होता है।

Explanation opens after your attempt
Correct Answer

A. (6)

Step 1

Concept

The total difference (26-2=24) splits into three equal gaps, so (d=8) and the second term should be (10); hence (x=10), but the third (3x=30), so there is no solution.

Step 2

Why this answer is correct

The correct answer is A. (6). The total difference (26-2=24) splits into three equal gaps, so (d=8) and the second term should be (10); hence (x=10), but the third (3x=30), so there is no solution.
