Question 1/5 Expert Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 3

यदि (a=18q+11), तो \(a^2+9\) को 18 से भाग देने पर शेषफल क्या होगा?

If (a=18q+11), what is the remainder when \(a^2+9\) is divided by 18?

Correct Answer

A. 2

Step 1

Concept

The remainder of (a) is 11.

Step 2

Why this answer is correct

The remainder of \(a^2+9\) comes from \(11^2+9=130\).

Step 3

Exam Tip

\(130=18\times7+4\), so the final remainder is 4. चरण 1: (a) का शेषफल 11 है। चरण 2: \(a^2+9\) का शेषफल \(11^2+9=130\) से मिलेगा। चरण 3: \(130=18\times7+4\), इसलिए अंतिम शेषफल 4 है।

C. 8

Step 1

Concept

The remainder of (a) is 9.

Step 2

Why this answer is correct

The remainder of \(a^2+7\) comes from \(9^2+7=88\).

Step 3

Exam Tip

\(88=16\times5+8\), so the final remainder is 8. चरण 1: (a) का शेषफल 9 है। चरण 2: \(a^2+7\) का शेषफल \(9^2+7=88\) से मिलेगा। चरण 3: \(88=16\times5+8\), इसलिए अंतिम शेषफल 8 है।

B. 6

Step 1

Concept

The remainder of (a) is 7.

Step 2

Why this answer is correct

The remainder of \(a^2+5\) comes from \(7^2+5=54\).

Step 3

Exam Tip

\(54=12\times4+6\), so the final remainder is 6. चरण 1: (a) का शेषफल 7 है। चरण 2: \(a^2+5\) का शेषफल \(7^2+5=54\) से मिलेगा। चरण 3: \(54=12\times4+6\), इसलिए अंतिम शेषफल 6 है।

Question 4/5 Hard Mathematics Chapter 1: Real Numbers 1: Euclid’s Division Lemma Class 10 Level 3

यदि (a=7q+3), तो \(a^2+2\) को 7 से भाग देने पर शेषफल क्या होगा?

If (a=7q+3), what is the remainder when \(a^2+2\) is divided by 7?

Explanation opens after your attempt
Correct Answer

A. 4

Step 1

Concept

The remainder of (a) is 3.

Step 2

Why this answer is correct

The remainder of \(a^2+2\) comes from \(3^2+2=11\), and (11=7+4).

Step 3

Exam Tip

Substitute the remainder in the expression, then find the final remainder. चरण 1: (a) का शेषफल 3 है। चरण 2: \(a^2+2\) का शेषफल \(3^2+2=11\) से मिलेगा, और (11=7+4)। चरण 3: व्यंजक में शेषफल रखकर फिर अंतिम शेषफल निकालें।

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

यदि (a=5q+2), तो \(a^2+1\) को 5 से भाग देने पर शेषफल क्या होगा?

If (a=5q+2), what is the remainder when \(a^2+1\) is divided by 5?

Explanation opens after your attempt
Correct Answer

A. 0

Step 1

Concept

The remainder of (a) is 2.

Step 2

Why this answer is correct

The remainder of \(a^2+1\) comes from \(2^2+1=5\), which is exactly divisible by 5.

Step 3

Exam Tip

After substituting the remainder in the expression, check it again by the divisor. चरण 1: (a) का शेषफल 2 है। चरण 2: \(a^2+1\) का शेषफल \(2^2+1=5\) से मिलेगा, जो 5 से पूर्णतः विभाजित है। चरण 3: व्यंजक में शेषफल रखने के बाद उत्तर को फिर भाजक से जांचें।
