Open The Safe Puzzle - Solution

The Puzzle:

Open The Safe
Ludwig Bump runs the bank in Mathsville.

You have to help him, though, because he has forgotten the combination number of the safe.

Fortunately, he does remember some things about the number which may help you to help him.

· The number has four digits (eg.1234 or 9876).
· All the digits are different.
· It begins and ends with an odd number and has two even numbers in the middle.
· 19 and 519 go into it exactly.

WHAT IS THE NUMBER WHICH WILL OPEN THE SAFE?




Our Solution:

The combination number of Ludwig Bump's bank safe in Mathsville is 9861.

A bit of a trick puzzle, really, because out of the five clues I gave, the last one alone gives you the answer: Just multiply 519 x 19 and you get 9861. The other clues are just for checking.
