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।

B. (2)

Step 1

Concept

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

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

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

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.

Step 3

Exam Tip

कुल अंतर (26-2=24) तीन समान भागों में बंटता है, इसलिए (d=8) और दूसरा पद (10) होना चाहिए; अतः (x=10), पर तीसरा (3x=30) होगा, इसलिए कोई समाधान नहीं।

The total difference (29-5=24) is split into three equal gaps, so (d=8), (x=13), and (y=21). For two missing terms, divide the total difference into equal gaps.

Step 2

Why this answer is correct

The correct answer is D. (34). The total difference (29-5=24) is split into three equal gaps, so (d=8), (x=13), and (y=21). For two missing terms, divide the total difference into equal gaps.

Step 3

Exam Tip

कुल अंतर (29-5=24) तीन बराबर भागों में बंटता है, इसलिए (d=8), (x=13), (y=21)। दो खाली पदों में कुल अंतर को बराबर अंतरालों में बांटें।

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

The total difference (14-2=12) is split into three equal gaps, so (d=4), and the second term should be (6), hence (x=5). Splitting the total difference into equal parts is useful.

Step 2

Why this answer is correct

The correct answer is B. (4). The total difference (14-2=12) is split into three equal gaps, so (d=4), and the second term should be (6), hence (x=5). Splitting the total difference into equal parts is useful.

Step 3

Exam Tip

कुल अंतर (14-2=12) तीन बराबर भागों में बंटेगा, इसलिए (d=4) और (x+1=6) नहीं बल्कि दूसरा पद (6) होना चाहिए, अतः (x=5)। कुल अंतर को समान भागों में बांटना उपयोगी है।

Explanation opens after your attempt
Correct Answer

C. (27)

Step 1

Concept

There are three equal gaps, so \(d=\frac{24-3}{3}=7\), hence (x=10) and (y=17). For two missing terms, split the total difference into equal gaps.

Step 2

Why this answer is correct

The correct answer is C. (27). There are three equal gaps, so \(d=\frac{24-3}{3}=7\), hence (x=10) and (y=17). For two missing terms, split the total difference into equal gaps.

Step 3

यदि (5,x,y,20) अंकगणितीय श्रेणी के क्रमागत पद हैं तो (x) और (y) के मान क्या होंगे?

If (5,x,y,20) are consecutive terms of an arithmetic progression, what will be the values of (x) and (y)?

Explanation opens after your attempt
Correct Answer

B. (x=10,y=15)

Step 1

Concept

There are three equal gaps from (5) to (20), so \(d=\frac{20-5}{3}=5\), hence (x=10) and (y=15). Find missing terms by splitting the total difference into equal gaps.

Step 2

Why this answer is correct

The HCF of two numbers is \(2^2\times 3^2\) and their LCM is \(2^5\times 3^2\times 5\times 7\). If one number is \(2^5\times 3^2\times 5\), what is the other number?

Write \(1260=126 \times 10\).

Step 2

Why this answer is correct

\(126=2 \times 3^2 \times 7\) and \(10=2 \times 5\), so \(1260=2^2 \times 3^2 \times 5 \times 7\). It does not include (11).

Step 3

Exam Tip

Match the options with the prime factorisation. चरण 1: \(1260=126 \times 10\) लिखें। चरण 2: \(126=2 \times 3^2 \times 7\) और \(10=2 \times 5\), इसलिए \(1260=2^2 \times 3^2 \times 5 \times 7\)। इसमें (11) नहीं है। चरण 3: विकल्पों को अभाज्य गुणनखंडन से मिलाएं।
