Question 1/16 Expert Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 3

यदि (t=46q+37), तो (6t+17) को 46 से भाग देने पर शेषफल क्या होगा?

If (t=46q+37), what is the remainder when (6t+17) is divided by 46?

Explanation opens after your attempt
Correct Answer

B. 9

Step 1

Concept

The remainder of (t) is 37.

Step 2

Why this answer is correct

The remainder part of (6t+17) is \(6\times37+17=239\).

Step 3

Exam Tip

\(239=46\times5+9\), so the final remainder is 9. चरण 1: (t) का शेषफल 37 है। चरण 2: (6t+17) का शेषफल \(6\times37+17=239\) से मिलेगा। चरण 3: \(239=46\times5+9\), इसलिए अंतिम शेषफल 9 है।

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।

Step 2

Why this answer is correct

(4n+5=68q+24+5=68q+29=17(4q+1)+12).

Step 3

Exam Tip

In a linear expression, first multiply the remainder and then reduce by the divisor. चरण 1: (n=17q+6) मानें। चरण 2: (4n+5=68q+24+5=68q+29=17(4q+1)+12)। चरण 3: रैखिक रूप में पहले शेषफल को गुणा करें और फिर भाजक से घटाएं।
