# Write all possible 3- digit numbers (without repeating the digits) , by using the digits.(i)6,7,5 (ii) 9,0,2

Solution:

(i)  Possible three digit number using the digits 6 , 7 , 5

Take 5 as first number,

567 , 576

Take 6 as first number,

657 , 675

Take 7 as first number,

756 , 765

So,   567 , 576 , 657 , 675 , 756 , 765  are the Possible three digit number using the

digits 6 , 7 , 5

ii)Possible three digit number using the digits 9 , 0 , 2

Take 2 as first number,
