Question

Q17. Find the difference between the greatest and the least number that can be written using the digits
2,5,8,7,3 each only once​

Answer 1

Answer:

63954

Step-by-step explanation:

Greatest number using these digits = 87532

Least number which can be written with these numbers = 23578

Difference = 87532-23578 = 63954

Answer 2

Answer:

Step 1

To find the greatest number

The easy way to find the greatest number using the given digits where each digit occurring only once is to arrange the digits in descending order and the number obtained will be the greatest number formed by the given digits.

The greatest number formed using the digits 6, 2, 7, 4, 3 and each digit occurring only once = 76,432

Step 2

To find the smallest number

The easy way to find the smallest number using the given digits where each digit occurring only once is to arrange the digits in ascending order and the number obtained will be the smallest number formed by the given digits.

The smallest number formed using the digits 6, 2, 7, 4, 3 and each digit occurring only once = 23,467

Step 3

Now  to find the difference between the above two numbers we get,

Difference between the greatest and smallest number=76,432 – 23,467

=52,965

Answer:

Hence, the difference between the greatest number and smallest number formed using the digits 6, 2, 7, 4, 3 each digit occurring only once= 52,965
