Question 374811
The given digits are 1,2,3,4,5
For the number to be divisible by 4 we should have the last two digits to be a multiple of 4
That is we should have the last two digits to be 2 and 4
so let us write the last two digits of as 2 4

now we are left with 11 places
these places are to be filled with any of the digits 1,2,3,4,5
so each place can be filled in 5 ways since repetition is allowed
so we have  5 * 5* 5* .... 11 times
so the total number = 5^11=48828125
similarly the last two digits may be 12  and 44
so with 12 and 44 also we get 5^11 = 48828125 
so total = 3* 48828125=146484375
This is the final answer
