A palindrome is a number that reads the same forward and backward, such as 242. How many even nine-digit numbers are palindromes?	Pick:
A) 40
B) 40000
C) 500
D) 5,000
E) 100,000
if the palindrome must be even, it must begin and end in 2,4 6 and 8 ( 4 ways) e.g 222212222,444414444.   The middle number in the nine-digit could be 0-9 ( 10 ways), e.g 22522, 22822   The 2nd and fourth numbers   , the 3rd and 5th and 4th and 6th could must also be same i.e 0-9( 10 ways) e.g 242343242, 648565846   we thus have, 4 *10*10*10*10=40000 40000
