Question 1/4
Hard Mathematics
Chapter 2: Polynomials Irrational numbers and real numbers Class 10 Level 25
कौन सा विकल्प \(\sqrt{99}\) और \(\sqrt{100}\) के बीच एक परिमेय संख्या है?
Which option is a rational number between \(\sqrt{99}\) and \(\sqrt{100}\)?
Explanation opens after your attempt
Step 1
Concept
\(\sqrt{99}\) is about (9.95) and \(\sqrt{100}=10\). (9.98) is a rational number between them.
Step 2
Why this answer is correct
The correct answer is A. (9.98). \(\sqrt{99}\) is about (9.95) and \(\sqrt{100}=10\). (9.98) is a rational number between them.
Step 3
Exam Tip
\(\sqrt{99}\) लगभग (9.95) है और \(\sqrt{100}=10\) है। (9.98) इनके बीच की परिमेय संख्या है।

Question 2/4
Medium Mathematics
Chapter 2: Polynomials Irrational numbers and real numbers Class 10 Level 27
कौन सा विकल्प \(\sqrt{11}\) के निकटतम दो पूर्णांकों को सही बताता है?
Which option correctly gives the two nearest integers between which \(\sqrt{11}\) lies?
Explanation opens after your attempt
Correct Answer
A. (3) और (4)/(3) and (4)
Step 1
Concept
Since (9<11<16), \(3<\sqrt{11}<4\). Estimate using squares.
Step 2
Why this answer is correct
The correct answer is A. (3) और (4) / (3) and (4). Since (9<11<16), \(3<\sqrt{11}<4\). Estimate using squares.
Step 3
Exam Tip
क्योंकि (9<11<16) इसलिए \(3<\sqrt{11}<4\)। वर्गों की मदद से अनुमान लगाएँ।

Question 3/4
Medium Mathematics
Chapter 2: Polynomials Irrational numbers and real numbers Class 10 Level 26
कौन सा विकल्प \(\sqrt{7}\) के निकटतम दो पूर्णांकों को सही बताता है?
Which option correctly gives the two nearest integers between which \(\sqrt{7}\) lies?
Explanation opens after your attempt
Correct Answer
A. (2) और (3)/(2) and (3)
Step 1
Concept
Since (4<7<9), \(2<\sqrt{7}<3\). Locate roots using squares.
Step 2
Why this answer is correct
The correct answer is A. (2) और (3) / (2) and (3). Since (4<7<9), \(2<\sqrt{7}<3\). Locate roots using squares.
Step 3
Exam Tip
क्योंकि (4<7<9) इसलिए \(2<\sqrt{7}<3\)। जड़ की स्थिति वर्गों से पहचानें।

Question 4/4
Medium Mathematics
Chapter 2: Polynomials Irrational numbers and real numbers Class 10 Level 25
कौन सा विकल्प \(\sqrt{2}\) के निकटतम दो पूर्णांकों को सही बताता है?
Which option correctly gives the two nearest integers between which \(\sqrt{2}\) lies?
Explanation opens after your attempt
Correct Answer
A. (1) और (2)/(1) and (2)
Step 1
Concept
Since (1<2<4), \(1<\sqrt{2}<2\). Use squares to locate roots.
Step 2
Why this answer is correct
The correct answer is A. (1) और (2) / (1) and (2). Since (1<2<4), \(1<\sqrt{2}<2\). Use squares to locate roots.
Step 3
Exam Tip
क्योंकि (1<2<4) इसलिए \(1<\sqrt{2}<2\)। वर्गों से जड़ की स्थिति पहचानें।
