Lou Zerr is trying to pick up a woman at a bar. The woman, Denise, is reluctant to give out her number, but she gives Lou a clue.
"My sister, Elise and I have the same digits in our phone numbers, just in reverse order. Elise's number is also evenly divisible by mine."
What is Denise's phone number?
(Note: this IS NOT a real exchange, as far as I know. Assume the phone number has 10 digits: 7 digit number + 3 digit area code.)
(In reply to re(3): Another non-trivial solution
So in the context of the question does 'evenly divisible' mean that it divides with no remainder (as Penny says) or that it divides with no remainder AND an even answer?
