An employee identification code consists of a vowel followed by a 3-digit number greater than 200. Exactly 2 of the 3 digits in the code should be identical. How many different codes is it possible to form?  Choose the correct answer:
A) 211
B) 216
C) 1075
D) 1080
E) 2160
For the case when the hundreds digit is repeated: XXY or XYX   X can take 8 values (2, 3, 4, 5, 6, 7, 8, 9).   Y can take 9 values (10 digits minus the one we used for X).   To account for XXY or XYX case we are multiplying by 2.   So, for this case we'd have 8*9*2.   For the case when the tens and units digits are repeated: XYY   X can take 8 values (2, 3, 4, 5, 6, 7, 8, 9).   Y can take 9 values (10 digits minus the one we used for X).   Now, 8*9 also give number 200 and we need numbers greater than 200, so for this case we'd have 8*9 - 1.   Last step, since there are 5 vowels, then the final answer would be 5*(8*9*2 + 8*9 - 1) = 1,075.   Answer: 1075.
