5. किसी टैक्सी ड्राइवर ने अपनी गाड़ी की पेट्रोल की टंकी मे सोमवार को\[40\]  लीटर तेल भरवाया । अगले दिन उसने टंकी मे \[50\] लीटर पेट्रोल भरताया । यदि पेट्रोल का मूल्य ₹\[44\] प्रति लीटर था, तो उसने पेट्रोल पर कुल कितना व्यय किया?

उत्तर:  सोमवार को पेट्रोल भरवाया\[=40\] लीटर
अगले दिन, टंकी में पेट्रोल भरवाया \[=50\] लीटर
कुल पेट्रोल भरवाया \[=40\text{ }+\text{ }50\text{ }=\text{ }90\] लीटर
चूँकि, \[1\] लीटर पेट्रोल की कीमत \[=44\]रूपये
इसलिए,\[90\] लीटर पेट्रोल की कीमत\[=90\text{ }\times \text{ }44\] रूपये
\[=\text{ }\left( 100-10 \right)\text{ }\times \text{ }44\]रूपये
\[=\text{ }\left( 100\text{ }\times \text{ }44 \right)\text{ }-\text{ }\left( 10\text{ }\times \text{ }44 \right)\]रूपये
\[=\text{ }4400-440\]रूपये
\[=\text{ }3960\]रूपये
इस तरह, ड्राइवर ने पेट्रोल पर \[\text{ }3960\] रूपये ख़र्च किया।

6. कोई दूध ताला एक होटल को सुबह \[32\] लीटर दूध देता है और शाम को \[68\] लीटर दूध देता है। यदि दूध का मूल्य \[45\]रूपये प्रति लीटर है, तो दूध ताले को प्रति दिन कितनी धनराशि प्राप्त होगी?

उत्तर:  दूध वाला एक होटल को सुबह में दूध देता है \[=32\] लीटर
शाम को दूध देता है\[=68\] लीटर
पूरे एक दिन में कुल दूध देता है \[=32\text{ }+\text{ }68\text{ }=\text{ }100\] लीटर
चूँकि,\[1\] लीटर दूध की कीमत  \[45\]रूपये
इसलिए, \[100\] लीटर दूध की कीमत \[45\text{ }\times \text{ }100\]रूपये\[=4500\] रूपये
इसतरह, दूधवाले को प्रतिदिन\[4500\]  रूपये प्राप्त होते हैं।

7. निम्न को सुमेलित कीजिए:

(i)\[425\times136=425\times(6+30+100)\]

(a) गुणन की क्रमविनिमेयता

(ii)\[2\times 49\times 50= 2\times 50\times 49\]  

(b) योग की क्रमविनिमेयता 

(iii)\[80+2005+20 = 80+20+2005\]

(c) योग पर गुणन का वितरण


उत्तर:  \[\left( i \right)\text{ }c,\text{ }\left( ii \right)\text{ }a,\text{ }\left( iii \right)\text{ }b\]

FAQs on NCERT Solutions for Class 6 Maths In Hindi Chapter 2 Whole Numbers

1. What are the key topics covered in the NCERT Solutions for Class 6 Maths Chapter 2, Whole Numbers?

The solutions cover all topics as per the CBSE 2025-26 syllabus, focusing on: the definition of whole numbers, representation on the number line, and properties like closure, commutativity, and associativity. Special emphasis is given to the distributive property of multiplication over addition and subtraction, which is key for simplifying calculations.

2. How do I find the correct step-by-step solution for a specific question in Exercise 2.1 or 2.2?

Our NCERT Solutions are organized by exercise. You can easily navigate to the specific exercise (e.g., Exercise 2.1, 2.2, or 2.3) from Chapter 2. Each question is solved in a step-by-step format, exactly as required by the CBSE pattern, making it easy to follow the correct method and logic for every problem.

3. What is the difference between natural numbers and whole numbers as explained in Chapter 2?

The primary difference is the inclusion of zero. Natural numbers are the counting numbers (1, 2, 3, ...), while whole numbers include all natural numbers plus zero (0, 1, 2, 3, ...). Therefore, every natural number is a whole number, but not every whole number (specifically 0) is a natural number.

4. Why is the distributive property of multiplication over addition important for solving problems in this chapter?

The distributive property (a × (b + c) = a × b + a × c) is crucial because it helps simplify complex multiplications. Instead of multiplying large numbers directly, you can break them down into simpler parts. For example, to solve 738 × 103, you can use the property to calculate (738 × 100) + (738 × 3), which is much easier. Our solutions demonstrate this problem-solving technique to make calculations faster and less error-prone.

5. How do the NCERT solutions demonstrate the use of a number line for whole number operations?

The solutions provide clear, visual explanations for performing operations on a number line.

  • For addition, they show how to move to the right from a number.
  • For subtraction, they show how to move to the left.
  • For multiplication, they demonstrate making repeated jumps of equal size.
This helps in understanding the concepts visually, not just memorising rules.

6. Can a whole number have a predecessor that is not a whole number?

Yes. The whole number 0 is a special case. Its predecessor (the number just before it) is -1. Since -1 is an integer and not a whole number, this shows that while most whole numbers have a whole number as their predecessor, the smallest whole number, 0, does not.

7. How do these NCERT Solutions for the 2025-26 session help in building a strong foundation in Maths?

These solutions focus on explaining the 'why' behind each step, not just the final answer. By following the detailed methodology for concepts like properties of whole numbers and number line operations, you build a logical understanding. This strong foundation is essential for mastering more complex topics like integers and algebra in higher classes.

8. What is a common mistake students make when finding the number of whole numbers between two given numbers, and how do the solutions address it?

A common mistake is to simply subtract the smaller number from the larger one. For instance, to find the whole numbers between 32 and 53, many students calculate 53 - 32 = 21. The correct method, shown in our solutions, is (Larger Number - Smaller Number) - 1, which is (53 - 32) - 1 = 20. The solutions explain this formula to ensure you get the exact count by excluding the endpoints.
