FAQs on NCERT Solutions for Class 6 Maths Chapter 3 Number Play Exercise 3.6
1. What is Kaprekar's Magic Number mentioned in Chapter 3: Number Play?
Kaprekar's Magic Number is 6174, which is reached by subtracting a number from its reverse repeatedly until the result is 6174.
2. How do you find the Magic Number of Kaprekar as explained in Exercise 3.6?
To find the magic number, rearrange the digits of a four-digit number in descending and ascending order, subtract the smaller from the larger, and repeat the process until you reach 6174.
3. What makes the number 6174 special in mathematics?
The number 6174 is special because, after a few iterations of subtracting the digits in a certain way, all four-digit numbers (excluding a few exceptions) will eventually reach 6174.
4. Why is Kaprekar's constant referred to as a 'magic number'?
It is called a magic number because, no matter what four-digit number (with at least two different digits) you start with, you will always reach 6174 after a few steps.
5. How many steps does it take to reach 6174 from any four-digit number?
It usually takes between 1 to 7 steps to reach 6174 from any four-digit number that follows the Kaprekar process.
6. Is 6174 the only magic number in mathematics?
No, there are other interesting numbers in mathematics with unique properties, but 6174 is particularly famous due to its simple yet fascinating iterative process.
7. What happens if all the digits of the number are the same, like 1111?
If all digits of a number are the same, Kaprekar's process results in zero, which is not applicable for reaching 6174.
8. What is the significance of digit manipulation in Kaprekar's process?
Digit manipulation helps explore patterns and properties of numbers, teaching students about mathematical operations and reasoning.
9. How does this exercise 3.6 help in improving problem-solving skills?
This exercise encourages students to think logically, perform iterative calculations, and recognize number patterns, all of which are essential for improving problem-solving skills.
10. Why is it important to learn about the Magic Number of Kaprekar in Class 6?
Learning about the magic number introduces students to mathematical patterns, logical reasoning, and unique properties of numbers, making maths more interesting and engaging.
