Question

When I glanced at my car milometer it showed 18981, a palindromic number (a number which reads the same backwards). Two days later, I noticed that it showed the next palindromic number.

How many miles did my car travel in those two days?

1. 100


2. 110


3. 200


4. 220


5. 1010

Answer 1

110 miles

Explanation:

See the attached worksheet. A spreadsheet was used to add each of the mileage options to the start of 18981 and observe which one was a palindrome. 110 miles added to 18981 is 19091, a palindrome.
