Question 1/7 Expert Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 3

यदि (p=23q+19), तो (7p-18) को 23 से भाग देने पर शेषफल क्या होगा?

If (p=23q+19), what is the remainder when (7p-18) is divided by 23?

Explanation opens after your attempt
Correct Answer

A. 0

Step 1

Concept

The remainder of (p) is 19.

Step 2

Why this answer is correct

The remainder of (7p-18) comes from \(7\times19-18=115\).

Step 3

Exam Tip

Since \(115=23\times5\), the final remainder is 0. चरण 1: (p) का शेषफल 19 है। चरण 2: (7p-18) का शेषफल \(7\times19-18=115\) से मिलेगा। चरण 3: \(115=23\times5\), इसलिए अंतिम शेषफल 0 है।

Question 2/7 Expert Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 2

यदि (p=19q+16), तो (6p-20) को 19 से भाग देने पर शेषफल क्या होगा?

If (p=19q+16), what is the remainder when (6p-20) is divided by 19?

Explanation opens after your attempt
Correct Answer

A. 0

Step 1

Concept

The remainder of (p) is 16.

Step 2

Why this answer is correct

The remainder of (6p-20) comes from \(6\times16-20=76\).

Step 3

Exam Tip

Since \(76=19\times4\), the final remainder is 0. चरण 1: (p) का शेषफल 16 है। चरण 2: (6p-20) का शेषफल \(6\times16-20=76\) से मिलेगा। चरण 3: \(76=19\times4\), इसलिए अंतिम शेषफल 0 है।

Question 3/7 Expert Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 1

यदि (p=17q+14), तो (5p-19) को 17 से भाग देने पर शेषफल क्या होगा?

If (p=17q+14), what is the remainder when (5p-19) is divided by 17?

Explanation opens after your attempt
Correct Answer

A. 0

Step 1

Concept

The remainder of (p) is 14.

Step 2

Why this answer is correct

The remainder of (5p-19) comes from \(5\times14-19=51\).

Step 3

Exam Tip

Since \(51=17\times3\), the final remainder is 0. चरण 1: (p) का शेषफल 14 है। चरण 2: (5p-19) का शेषफल \(5\times14-19=51\) से मिलेगा। चरण 3: \(51=17\times3\), इसलिए अंतिम शेषफल 0 है।

Question 4/7 Hard Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 3

यदि (p=13q+11), तो (4p-9) को 13 से भाग देने पर शेषफल क्या होगा?

If (p=13q+11), what is the remainder when (4p-9) is divided by 13?

Explanation opens after your attempt
Correct Answer

A. 9

Step 1

Concept

The remainder of (p) is 11.

Step 2

Why this answer is correct

The remainder of (4p-9) comes from \(4\times11-9=35\), and \(35=13\times2+9\).

Step 3

Exam Tip

Always reduce the final remainder below the divisor. चरण 1: (p) का शेषफल 11 है। चरण 2: (4p-9) का शेषफल \(4\times11-9=35\) से मिलेगा, और \(35=13\times2+9\)। चरण 3: अंतिम शेषफल को हमेशा भाजक से कम करें।

Question 5/7 Hard Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 2

यदि (p=11q+8), तो (3p-7) को 11 से भाग देने पर शेषफल क्या होगा?

If (p=11q+8), what is the remainder when (3p-7) is divided by 11?

Explanation opens after your attempt
Correct Answer

B. 6

Step 1

Concept

The remainder of (p) is 8.

Step 2

Why this answer is correct

For (3p-7), the remainder part is \(3\times8-7=17\), and (17=11+6).

Step 3

Exam Tip

In a linear expression, always reduce the final remainder below the divisor. चरण 1: (p) का शेषफल 8 है। चरण 2: (3p-7) में शेषफल \(3\times8-7=17\) होगा, और (17=11+6)। चरण 3: रैखिक व्यंजक में अंतिम शेषफल हमेशा भाजक से छोटा करें।

Question 6/7 Medium Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 4

यदि (a=13q+1), तो (a-3) को (13) से भाग देने पर शेषफल क्या होगा?

If (a=13q+1), what is the remainder when (a-3) is divided by (13)?

Explanation opens after your attempt
Correct Answer

A. (11)

Step 1

Concept

(a-3=13q-2), but the remainder should not be negative.

Step 2

Why this answer is correct

(13q-2=13(q-1)+11), so the remainder is (11).

Step 3

Exam Tip

When a negative remainder appears, add the divisor to make the correct remainder. चरण 1: (a-3=13q-2) मिलता है, पर शेषफल ऋणात्मक नहीं होना चाहिए। चरण 2: (13q-2=13(q-1)+11), इसलिए शेषफल (11) है। चरण 3: ऋणात्मक शेषफल मिलने पर भाजक जोड़कर सही शेषफल बनाएं।

Question 7/7 Medium Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 4

यदि (a=20q+17), तो (a-5) को (20) से भाग देने पर शेषफल क्या होगा?

If (a=20q+17), what is the remainder when (a-5) is divided by (20)?

Explanation opens after your attempt
Correct Answer

B. (12)

Step 1

Concept

In (a=20q+17), the remainder is (17).

Step 2

Why this answer is correct

(a-5=20q+12), so the remainder is (12).

Step 3

Exam Tip

In subtraction-based questions, subtract the given number from the old remainder. चरण 1: (a=20q+17) में शेषफल (17) है। चरण 2: (a-5=20q+12), इसलिए शेषफल (12) होगा। चरण 3: घटाव वाले प्रश्न में पुराने शेषफल से घटाई गई संख्या घटाएं।
