Question

4 digit numbers to be formed out the fogures 0 1 2 3 4 no of digit is reapeted thhen number of such numbers is

Answer 1

Answer:

greatest number:4310 ; smallest number:1034

Step-by-step explanation:

To form the greatest number, we arrange the digits in descending order

We get,

4 greater than three which is greater than 2 which is greater than one which is greater than 0

therefore the number is 43210

To form the smallest number, we arrange the digits in descending order but we never keep 0 at 1st as we have to form the smallest 4 digit number and keep the next smallest  digit

we get,

3 then 0 which is smaller than 1 which is smaller than 2 which is smaller than 3 which is smaller than 4
