\(10-\sqrt{6}\) किस प्रकार की संख्या है?

What type of number is \(10-\sqrt{6}\)?

Explanation opens after your attempt
Correct Answer

A. अपरिमेय संख्याIrrational number

Step 1

Concept

Subtracting an irrational number from a rational number gives an irrational result. \(\sqrt{6}\) is irrational because (6) is not a perfect square.

Step 2

Why this answer is correct

The correct answer is A. अपरिमेय संख्या / Irrational number. Subtracting an irrational number from a rational number gives an irrational result. \(\sqrt{6}\) is irrational because (6) is not a perfect square.

Step 3

Exam Tip

In subtraction, check the final form as divisor times quotient plus remainder. चरण 1: (m=31q+6) लिखें। चरण 2: (m-68=31q-62=31(q-2)), इसलिए शेषफल 0 है। चरण 3: घटाव में अंतिम रूप को \(भाजक\timesभागफल+शेषफल\) की तरह जांचें।

यदि (a=37q+29), तो (a-48) को 37 से भाग देने पर शेषफल क्या होगा?

If (a=37q+29), what is the remainder when (a-48) is divided by 37?

Explanation opens after your attempt
Correct Answer

C. 18

Step 1

Concept

(a-48=37q+29-48=37q-19).

Step 2

Why this answer is correct

This can be written as (37(q-1)+18), so the remainder is 18.

Step 3

Exam Tip

Add the divisor once to make a negative remainder valid. चरण 1: (a-48=37q+29-48=37q-19)। चरण 2: इसे (37(q-1)+18) लिखा जा सकता है, इसलिए शेषफल 18 है। चरण 3: ऋणात्मक शेषफल को वैध बनाने के लिए एक बार भाजक जोड़ें।

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।

यदि (m) को 17 से भाग देने पर शेषफल 4 है, तो (m-23) को 17 से भाग देने पर शेषफल क्या होगा?

If (m) leaves remainder 4 when divided by 17, what is the remainder when (m-23) is divided by 17?

Explanation opens after your attempt
Correct Answer

A. 15

Step 1

Concept

Write (m=17q+4).

Step 2

Why this answer is correct

(m-23=17q-19=17(q-2)+15), so the remainder is 15.

Step 3

Exam Tip

If subtraction gives a negative remainder, add the divisor as needed. चरण 1: (m=17q+4) लिखें। चरण 2: (m-23=17q-19=17(q-2)+15), इसलिए शेषफल 15 है। चरण 3: घटाव में ऋणात्मक शेषफल आए तो भाजक को जरूरत के अनुसार जोड़ें।

यदि (a=29q+20), तो (a-35) को 29 से भाग देने पर शेषफल क्या होगा?

If (a=29q+20), what is the remainder when (a-35) is divided by 29?

Explanation opens after your attempt
Correct Answer

A. 14

Step 1

Concept

(a-35=29q+20-35=29q-15).

Step 2

Why this answer is correct

This can be written as (29(q-1)+14), so the remainder is 14.

Step 3

Exam Tip

Add the divisor to a negative remainder to make it valid. चरण 1: (a-35=29q+20-35=29q-15)। चरण 2: इसे (29(q-1)+14) लिखा जा सकता है, इसलिए शेषफल 14 है। चरण 3: ऋणात्मक शेषफल को वैध बनाने के लिए भाजक जोड़ें।

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।

यदि (m) को 12 से भाग देने पर शेषफल 5 है, तो (m-19) को 12 से भाग देने पर शेषफल क्या होगा?

If (m) leaves remainder 5 when divided by 12, what is the remainder when (m-19) is divided by 12?

Explanation opens after your attempt
Correct Answer

A. 10

Step 1

Concept

Write (m=12q+5).

Step 2

Why this answer is correct

(m-19=12q-14=12(q-2)+10), so the remainder is 10.

Step 3

Exam Tip

If subtraction gives a negative remainder, add the divisor enough times to make it valid. चरण 1: (m=12q+5) लिखें। चरण 2: (m-19=12q-14=12(q-2)+10), इसलिए शेषफल 10 है। चरण 3: घटाव में ऋणात्मक शेषफल आए तो भाजक को उचित बार जोड़कर वैध शेषफल बनाएं।
