A palindrome is a number which reads the same when read forward as it it does when read backward. So, how many 5 digit palindromes are there?
Choose the correct choice from the following answers:
A) 720
B) 800
C) 890
D) 900
E) 950
5 digit palindrome would look like this : abcba.abcba.   Thus, the first digit can be filled in 9 ways(1-9), the second digit can be filled in 10 ways (0-9) and the 3rd digit can again be filled in 10 ways. The last 2 digits would just mirror the already selected digit. Thus, the no of ways : 9*10*10*1*1=
