How many 4 digit number can be formed by 0,1,2,3,4,5 divisible by 4 with repetition
My Approach:
Last two digits can be 00,04,12,20,24,32,40,44,52 that is 9 possibilities for last two digits.
For the hundredth place digit all 6 possibilities exist.For the thousand place we have 5 options (1,2,3,4,5 ).
Hence the solution is 5*6*9=270
Is my solution correct? Please correct me if I am wrong.
