एक पुस्तकालय की पहली शेल्फ में (32) पुस्तकें हैं और हर अगली शेल्फ में (4) पुस्तकें अधिक हैं। (25)वीं शेल्फ में कितनी पुस्तकें होंगी?

A library has (32) books on the first shelf and each next shelf has (4) more books. How many books will be on the (25)th shelf?

Explanation opens after your attempt
Correct Answer

B. (128)

Step 1

Concept

\(a_{25}=32+24\times4=128\). Up to the (25)th shelf the difference is added (24) times.

Step 2

Why this answer is correct

The correct answer is B. (128). \(a_{25}=32+24\times4=128\). Up to the (25)th shelf the difference is added (24) times.

Step 3

Exam Tip

\(a_{25}=32+24\times4=128\)। (25)वीं शेल्फ तक अंतर (24) बार जुड़ता है।

Question Expert Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 53

एक पुस्तकालय में दो प्रकार की पुस्तकों की कुल संख्या (58) है और पहले प्रकार की संख्या दूसरे से (12) अधिक है। ग्राफीय समाधान क्या होगा?

A library has (58) books of two types, and the first type is (12) more than the second. What will be the graphical solution?

Explanation opens after your attempt
Correct Answer

A. ((35,23))

Step 1

Concept

The equations are (x+y=58) and (x-y=12), giving (x=35), (y=23). In word problems, first define the variables clearly.

Step 2

Why this answer is correct

The correct answer is A. ((35,23)). The equations are (x+y=58) and (x-y=12), giving (x=35), (y=23). In word problems, first define the variables clearly.

Step 3

Exam Tip

समीकरण (x+y=58) और (x-y=12) हैं, जिनसे (x=35), (y=23)। शब्द-प्रश्न में पहले चर स्पष्ट तय करें।

Question Hard Mathematics Real Numbers HCF and LCM using prime factorisation Class 10 Level 13

एक पुस्तकालय में (168) गणित की पुस्तकें और (252) विज्ञान की पुस्तकें हैं। इन्हें अधिकतम समान डिब्बों में रखना है ताकि हर डिब्बे में दोनों प्रकार की पुस्तकों की संख्या समान रहे। अधिकतम कितने डिब्बे बनेंगे?

A library has (168) mathematics books and (252) science books. They are to be kept in the maximum number of identical boxes so that each box has the same number of both types of books. How many boxes can be made?

Explanation opens after your attempt
Correct Answer

C. (84)

Step 1

Concept

The maximum number of identical boxes is found using HCF.

Step 2

Why this answer is correct

\(168=2^3\times3\times7\) and \(252=2^2\times3^2\times7\), so HCF \(=2^2\times3\times7=84\).

Step 3

Exam Tip

For maximum equal distribution, use HCF. चरण 1: अधिकतम समान डिब्बों की संख्या महत्तम समापवर्तक से मिलती है। चरण 2: \(168=2^3\times3\times7\) और \(252=2^2\times3^2\times7\), इसलिए महत्तम समापवर्तक \(2^2\times3\times7=84\) है। चरण 3: अधिकतम समान बाँटने में महत्तम समापवर्तक उपयोग करें।

Question Easy Mathematics Real Numbers HCF and LCM using prime factorisation Class 10 Level 12

एक पुस्तकालय में (48) विज्ञान की पुस्तकें और (72) गणित की पुस्तकें हैं। उन्हें समान ढेरों में अधिकतम कितने ढेरों में रखा जा सकता है?

A library has (48) science books and (72) mathematics books. In how many maximum equal piles can they be arranged?

Explanation opens after your attempt
Correct Answer

C. (24)

Step 1

Concept

For the maximum number of equal piles, find the HCF of (48) and (72).

Step 2

Why this answer is correct

\(48=2^4\times3\) and \(72=2^3\times3^2\), so HCF \(=2^3\times3=24\).

Step 3

Exam Tip

Maximum equal piles are found using HCF. चरण 1: समान ढेरों की अधिकतम संख्या के लिए (48) और (72) का महत्तम समापवर्तक चाहिए। चरण 2: \(48=2^4\times3\) और \(72=2^3\times3^2\), इसलिए महत्तम समापवर्तक \(2^3\times3=24\)। चरण 3: अधिकतम समान ढेर हमेशा महत्तम समापवर्तक से मिलते हैं।
