Answer 2

Answer:

48

Step-by-step explanation:

3 digit number is to be formed using digits 0,1,2,3,5 without repeatition.

1)For 1st place(Hundredth place) we have 4 choices(0 is not possible in hundredth place otherwise number so formed will be two digit number)

2) For 2nd place(Tenth place) 4 choices are there ( beacause one of the digit (1,2,3,5) is used in hundredth place so it cam not be repeated again)

3) and in similar way for remaining place (Unit place) there are 3 choices.

So by principle of Multiplication,

Total no of ways in which 3 digit number can be formed = 4*4*3 =48

So total 48 different Three digit numbers can be formed.
