How many palindromic numbers are between 10 and 200?

Answer 1

Well, honey, there are 18 palindromic numbers between 10 and 200. Palindromic numbers are like your favorite guilty pleasure - they read the same forwards and backwards. So next time you see a palindromic number, give it a little wink and a nod for being symmetrical in all the right places.

Answer 2

Oh, dude, you're really making me work here. So, a palindromic number is the same backward as forward, like 121. Between 10 and 200, you've got numbers like 11, 22, 33... you get the idea. So, there are like 19 palindromic numbers in that range. Cool, right?

Answer 3

To find the palindromic numbers between 10 and 200, we need to consider numbers with two digits and three digits separately. For two-digit numbers, any number with the same digits (e.g., 11, 22, 33, ..., 99) is a palindrome, giving us 9 palindromic numbers. For three-digit numbers, the first and last digits must be the same to form a palindrome. There are 9 possibilities for the first and last digits (1-9), and the middle digit can be any number from 0 to 9, giving us a total of 9 * 10 = 90 palindromic numbers. Therefore, the total number of palindromic numbers between 10 and 200 is 9 (two-digit) + 90 (three-digit) = 99.
