Answer 1

Their can be many answers to this question.
Tens digit can only be 1,2,3 as the thousands digit is 3 times tens.
Therefore thousand digit can only be 3,6or9.
Hundreds digit is even so it can be 2,4,6 or 8
Unit digit is an odd number less than 5 which means 1 or 3 .
As I said there are many possibilities.
