Question 350843

3 digit numbers number means we have to put 0-9 digit at 3 places....ABC

at the position of A (first place)  we can put any digit 1-9 not 0, otherwise it will not a 3 digit number, so by 9 ways

at the position of B (second place) we can put 0-9  i.e by 10 ways...

at the position of C (third place)  we can put 0,2,4,6 or 8  i.e by 5 ways...

so, total no. of digit = 9*10*5 = 450 


Total no. of  three digit even numbers =450
