How many even four digit numbers without repetition can be made up of the six numbers 0, 1, 2, 3, 4 and 5

When the last digit is 0, there are 5 * 4 * 3 = 120 kinds
When the last digit is 2 or 4, the first digit can't be 0, so there are four choices for the first digit. A total of 2 * 4 * 4 * 3 = 96
So the final answer is 120 + 96 = 216
