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.)

Disclaimer: I already know these guesses are uninteresting, didn't require much thought, and are probably not the intended solution.  But technically they fit the bill, so I wanted to throw them out there.

Denise: (111) 111-1111,  Elise: (111) 111-1111

Denise: (000) 000-0001,  Elise: (100) 000-0000

Denise: (000) 001-1111,  Elise: (111) 110-0000

Anything like these (10 of the same digit in a row, or 5-9 zeros followed by 1-5 of a repeated digit) would fit the bill (since the phone number doesn't have to have a real exchange).

Later!
