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,
209 , 290
Take 9 as first number,
902 , 920
We cant take 0 as first number, because 092 , 029 are two digit number.
So, 209 , 290 , 902 , 920 are the Possible three digit number using the digits 9 , 0 , 2
