A palindrome is a number that reads the same forward and backward, such as 242. How many even five-digit numbers are palindromes?
Choose the correct choice from the following options
A) 40 B) 400 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 22122,44144.   The middle number in the five-digit could be 0-9 ( 10 ways), e.g 22522, 22822   The 2nd and fourth numbers could must also be same i.e 0-9( 10 ways) e.g 23432, 85658   we thus have, 4 *10*10 = 400.   answer is 400 ( 400)
