How many 4-digit even numbers can be created?
I know that in unit place we can have 5 cases (0, 2, 4, 6, 8). In the leading position (thousandth place), should zero be allowed? 10 x 10 x 10 x 5 9 x 10 x 10 x 5 (This is what I believe should be the answer) If either of these options are available, then we can choose any one. But what if both of these exists in the exam, then which one is correct?

Can some one please tell me how are we finding solutions, for example when x = 3 how is number of solutions of y + z is 20. Three variables x,y,z have sum of 30. All three of them are non-negative integers. If any two variables don't have same value and exactly one variable has a value less than or equal to three, then find the number of possible solution for variables.
